The Posix implementation of guest-set-time invokes hwclock to
set/retrieve the time to/from the hardware clock. If hwclock
is not available, the user is currently informed that "hwclock
failed to set hardware clock to system time", which is quite
misleading. This may happen e.g. on s390x, which has a different
timekeeping concept anyway.
Let's check for the availability of the hwclock command and
return QERR_UNSUPPORTED for guest-set-time if it is not available.

Network interface name is fetched as an encoded WCHAR array, (wide
character), then it is decoded using the guest's CP_ACP Windows code
page, which is the default code page as configure in the guest's
Windows, then it is returned as a byte array, (char array).
As stated in the BZ#1733165, when renaming a network interface to a
Chinese name and invoking this command, the returned name field has
the (\ufffd) value for each Chinese character the name had, this
value is an indication that the code page does not have the decoding
information for the given character.
This bug is a result of using the CP_ACP code page for decoding which
is an interchangeable code page, instead CP_UTF8 code page should be
used for decoding the network interface's name.

Commit 7be41675f7 set -std=gnu99 for C code via QEMU_CFLAGS. Currently
we generate a "custom" QEMU_CXXFLAGS for VSS DLL C++ build by
filtering out some options from QEMU_CFLAGS and adding some others.
Since we don't filter out -std=gnu99 currently this breaks builds when
VSS support is enabled.
We could keep the existing approach, filter out -std=gnu99 from
QEMU_CFLAGS, and add -std=gnu++98, like configure currently does for
QEMU_CXXFLAGS, but as it turns out our resulting QEMU_CXXFLAGS would
be exactly what configure already generates, just with these filtered
out:
-fstack-protector-all -fstack-protector-strong
and these added:
-Wno-unknown-pragmas -Wno-delete-non-virtual-dtor

Commit 3ebee3b191 defined assert() as g_assert(), but when we build
the VSS DLL component of QGA (to handle fsfreeze) we do not include
glib, which results in breakage when building with VSS support enabled.
Fix this by including glib (along with the -lintl and -lws2_32
dependencies it brings).
Since the VSS DLL is built statically, this introduces an additional
dependency on static glib and supporting libs for the mingw environment
(possibly why we didn't include glib originally), but VSS support
already has very specific prerequisites so it shouldn't affect too many
build environments.
Since the VSS DLL code does use qemu/osdep.h, this should also help
avoid future breakages and possibly allow for some clean ups in current
VSS code.

Since Windows Server 2016, Microsoft stopped upgrading the major and minor
versions of their new Windows Server product, so, the current functionality
of checking major and minor version numbers to determine the Windows Server
version wont work as expected.
The implemented solution here is to use the build number in addition to the
major and minor version numbers of the product to determine the Windows
Server product version.
The final build number of Windows Server 2016 is 14939, and
the final build number of Windows Server 2019 is 17764, so any Windows
Server product that has the major version of 10 and minor version of 0
with a build number lower or equal to 14939 will resemble 2016 and if the
build number is lower or equal to 17763 will resemble 2019.

It's nicer from a management perspective that the agent can survive
hotplug/unplug of the channel device, or be started prior to the
installation of the channel device's driver without and still be able
to resume normal function afterward. On linux there are alternatives
like systemd to support this, but on w32 --retry-path is the only
option so it makes sense to set it by default when installed as a
w32 service.

This adds an option to instruct the agent to periodically attempt
re-opening the communication channel after a channel error has
occurred. The main use-case for this is providing an OS-independent
way of allowing the agent to survive situations like hotplug/unplug of
the communication channel, or initial guest set up where the agent may
be installed/started prior to the installation of the channel device's
driver.
There are nicer ways of implementing this functionality via things
like systemd services, but this option is useful for platforms like
*BSD/w32.
Currently a channel error will result in the GSource for that channel
being removed from the GMainLoop, but the main loop continuing to run.
That behavior results in a dead loop when --retry-path isn't set, and
prevents us from knowing when to attempt re-opening the channel when
it is set, so we also force the loop to exit as part of this patch.

The callback to consume JSON values takes QObject *json, Error *err.
If both are null, the callback is supposed to make up an error by
itself. This sucks.
qjson.c's consume_json() neglects to do so, which makes
qobject_from_json() null instead of failing. I consider that a bug.
The culprit is json_message_process_token(): it passes two null
pointers when it runs into a lexical error or a limit violation. Fix
it to pass a proper Error object then. Update the callbacks:
* monitor.c's handle_qmp_command(): the code to make up an error is
now dead, drop it.
* qga/main.c's process_event(): lumps the "both null" case together
with the "not a JSON object" case. The former is now gone. The
error message "Invalid JSON syntax" is misleading for the latter.
Improve it to "Input must be a JSON object".
* qobject/qjson.c's consume_json(): no update; check-qjson
demonstrates qobject_from_json() now sets an error on lexical
errors, but still doesn't on some other errors.
* tests/libqtest.c's qmp_response(): the Error object is now reliable,

The classical way to structure parser and lexer is to have the client
call the parser to get an abstract syntax tree, the parser call the
lexer to get the next token, and the lexer call some function to get
input characters.
Another way to structure them would be to have the client feed
characters to the lexer, the lexer feed tokens to the parser, and the
parser feed abstract syntax trees to some callback provided by the
client. This way is more easily integrated into an event loop that
dispatches input characters as they arrive.
Our JSON parser is kind of between the two. The lexer feeds tokens to
a "streamer" instead of a real parser. The streamer accumulates
tokens until it got the sequence of tokens that comprise a single JSON
value (it counts curly braces and square brackets to decide). It
feeds those token sequences to a callback provided by the client. The
callback passes each token sequence to the parser, and gets back an
abstract syntax tree.
I figure it was done that way to make a straightforward recursive
descent parser possible. "Get next token" becomes "pop the first
token off the token sequence". Drawback: we need to store a complete
token sequence. Each token eats 13 + input characters + malloc
overhead bytes.
Observations:
1. This is not the only way to use recursive descent. If we replaced
"get next token" by a coroutine yield, we could do without a
streamer.
2. The lexer reports errors by passing a JSON_ERROR token to the
streamer. This communicates the offending input characters and
their location, but no more.
3. The streamer reports errors by passing a null token sequence to the
callback. The (already poor) lexical error information is thrown
away.
4. Having the callback receive a token sequence duplicates the code to
convert token sequence to abstract syntax tree in every callback.
5. Known bug: the streamer silently drops incomplete token sequences.
This commit rectifies 4. by lifting the call of the parser from the
callbacks into the streamer. Later commits will address 3. and 5.
The lifting removes a bug from qjson.c's parse_json(): it passed a
pointer to a non-null Error * in certain cases, as demonstrated by
check-qjson.c.
json_parser_parse() is now unused. It's a stupid wrapper around
json_parser_parse_err(). Drop it, and rename json_parser_parse_err()
to json_parser_parse().

Commit cf869d5317 "qmp: support out-of-band (oob) execution"
accidentally made qemu-ga accept and ignore "control". Fix that.
Out-of-band execution in a monitor that doesn't support it now fails
with
{"error": {"class": "GenericError", "desc": "QMP input member 'control' is unexpected"}}
instead of
{"error": {"class": "GenericError", "desc": "Please enable out-of-band first for the session during capabilities negotiation"}}
The old description is suboptimal when out-of-band cannot not be
enabled, or the command doesn't support out-of-band execution.
The new description is a bit unspecific, but it'll do.

bios_support_mode verifies if the guest has support for a certain
suspend mode but it doesn't inform back which suspend tool
provides it. The caller, guest_suspend, executes all suspend
strategies in order again.
After adding systemd suspend support, bios_support_mode now will
verify for support for systemd, then pmutils, then Linux sys state
file. In a worst case scenario where both systemd and pmutils isn't
supported but Linux sys state is:
- bios_supports_mode will check for systemd, then pmutils, then
Linux sys state. It will tell guest_suspend that there is support,
but it will not tell who provides it;
- guest_suspend will try to execute (and fail) systemd suspend,
then pmutils suspend, to only then use the Linux sys suspend.
The time spent executing systemd and pmutils suspend was wasted
and could be avoided, but only bios_support_mode knew it but
didn't inform it back.
A quicker approach is to nuke bios_supports_mode and control
whether we found support at all with a bool flag inside
guest_suspend. guest_suspend will search for suspend support
and execute it as soon as possible. If the a given suspend
mechanism fails, continue to the next. If no suspend
support is found, the "not supported" message is still being
sent back to the user.

pmutils isn't being supported by newer OSes like Fedora 27
or Mint. This means that the only suspend option QGA offers
for these guests are writing directly into the Linux sys state
file. This also means that QGA also loses the ability to do
hybrid suspend in those guests - this suspend mode is only
available when using pmutils.
Newer guests can use systemd facilities to do all the suspend
types QGA supports. The mapping in comparison with pmutils is:
- pm-hibernate -> systemctl hibernate
- pm-suspend -> systemctl suspend
- pm-suspend-hybrid -> systemctl hybrid-sleep
To discover whether systemd supports these functions, we inspect
the status of the services that implements them.
With this patch, we can offer hybrid suspend again for newer
guests that do not have pmutils support anymore.

This is a cleanup of the resulting code after detaching
pmutils and Linux sys state file logic:
- remove the SUSPEND_MODE_* macros and use an enumeration
instead. At the same time, drop the switch statements
at the start of each function and use the enumeration
index to get the right binary/argument;
- create a new function called run_process_child(). This
function uses g_spawn_sync() to execute a shell command,
returning the exit code. This is a common operation in the
pmutils functions and will be used in the systemd implementation
as well, so this function will avoid code repetition.
There are more places inside commands-posix.c where this new
run_process_child function can also be used, but one step
at a time.

In bios_supports_mode there is a verification to assert if
the chosen suspend mode is supported by the pmutils tools and,
if not, we see if the Linux sys state files supports it.
This verification is done in the same function, one after
the other, and it works for now. But, when adding a new
suspend mechanism that will not necessarily follow the same
return 0 or 1 logic of pmutils, this code will be hard
to deal with.
This patch decouple the two existing logics into their own
functions, pmutils_supports_mode and linux_sys_state_supports_mode,
which in turn are used inside bios_support_mode. The existing
logic is kept but now it's easier to extend it.

Iterate over the PCI bridges to lookup the PCI device associated with

This allows to lookup the driver under the following syspath:
/sys/devices/pci0000:00/0000:00:02.2/0000:03:00.0/virtio2/block/vda/vda3
It also works with an "old-style" Q35 libvirt hierarchy: root complex
-> DMI-PCI bridge -> PCI-PCI bridge -> virtio controller, ex:
/sys/devices/pci0000:00/0000:00:03.0/0000:01:01.0/0000:02:01.0/virtio1/block/vda/vda3
The setup can be reproduced with the following qemu command line
(Thanks Marcel for help):
qemu-system-x86_64 -M q35 \
-device i82801b11-bridge,id=dmi2pci_bridge,bus=pcie.0
-device pci-bridge,id=pci_bridge,bus=dmi2pci_bridge,addr=0x1,chassis_nr=1
-device virtio-blk-pci,scsi=off,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1,bus=pci_bridge,addr=0x1
For consistency with other syspath-related debug messages, replace a
\"%s\" in the message with '%s'.

Per supported platforms doc[1], the various min glib on relevant distros is:
RHEL-7: 2.50.3
Debian (Stretch): 2.50.3
Debian (Jessie): 2.42.1
OpenBSD (Ports): 2.54.3
FreeBSD (Ports): 2.50.3
OpenSUSE Leap 15: 2.54.3
SLE12-SP2: 2.48.2
Ubuntu (Xenial): 2.48.0
macOS (Homebrew): 2.56.0
This suggests that a minimum glib of 2.42 is a reasonable target.
The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only
has glib 2.40.0, and this is needed for testing during merge. Thus an
exception is made to the documented platform support policy to allow for
all three current LTS releases to be supported.
Docker jobs that not longer satisfy this new min version are removed.

The replacement is mechanical, except I broke a long line, and added a

Since commit 67a1de0d19 there is no space anymore between the
version number and the parentheses when running configure with
--with-pkgversion=foo :
$ qemu-system-s390x --version
QEMU emulator version 2.11.50(foo)
But the space is included when building without that option
when building from a git checkout:
$ qemu-system-s390x --version
QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty)
The same confusion exists with the "query-version" QMP command.
Let's fix this by introducing a proper QEMU_FULL_VERSION definition
that includes the space and parentheses, while the QEMU_PKGVERSION
should just cleanly contain the package version string itself.
Note that this also changes the behavior of the "query-version" QMP
command (the space and parentheses are not included there anymore),
but that's supposed to be OK since the strings there are not meant
to be parsed by other tools.

Add test for guest-get-osinfo command.
Qemu-ga was modified to accept QGA_OS_RELEASE environment variable. If
the variable is defined it is interpreted as path to the os-release file
and it is parsed instead of the default paths.

Commit 161a56a906 added command guest-get-users and requires the
utmpx.h (defined by POSIX) to work. It is however not always available
(e.g. on OpenBSD) therefor a check for its existence is necessary.

glib depends on libpcre which was not shipped with the MSI, thus
starting of the qemu-ga.exe failed with the respective error message.
Tell WIXL to ship this library with the MSI to avoid this problem.

Replace hardcoded user and group names ("Administrators", "SYSTEM") with the ones acquired from system. Windows uses localized strings for these names and it may cause the installation to fail.
Windows has Well-known SIDs for "Administrators" group and "SYSTEM" user so they were used to identify required users and groups.
