0e90127d9b qga: conditionalize schema for commands unsupported on Windows
Rather than creating stubs for every command that just return
QERR_UNSUPPORTED, use 'if' conditions in the QAPI schema to
fully exclude generation of the commands on Windows.

The command will be rejected at QMP dispatch time instead,
avoiding reimplementing rejection by blocking the stub commands.
This changes the error message for affected commands from

    {"class": "CommandNotFound", "desc": "Command FOO has been disabled"}

to

    {"class": "CommandNotFound", "desc": "The command FOO has not been found"}

This also fixes an accidental inconsistency where some commands
(guest-get-diskstats & guest-get-cpustats) are implemented as
stubs, yet not added to the blockedrpc list. Those change their
error message from

    {"class": "GenericError, "desc": "this feature or command is not currently supported"}

to

    {"class": "CommandNotFound", "desc": "The command FOO has not been found"}

The final additional benefit is that the QGA protocol reference
now documents what conditions enable use of the command.

cec07c79a4 qga: Shorten several error messages
Some, but not all error messages are of the form

    Guest agent command failed, error was '<actual error message>'

For instance, command guest-exec can fail with an error message like

    Guest agent command failed, error was 'Failed to execute child process “/bin/invalid-cmd42” (No such file or directory)'

Shorten this to just just the actual error message.  The guest-exec
example becomes

    Failed to execute child process “/bin/invalid-cmd42” (No such file or directory)

ecfc9890c4 qga-win32: Improve guest-set-user-password, guest-file-open errors
When guest-set-user-password's argument @password can't be converted
from UTF-8 to UTF-16, we report something like

    Guest agent command failed, error was 'Invalid sequence in conversion input'

Improve this to

    can't convert 'password' to UTF-16: Invalid sequence in conversion input

Likewise for argument @username, and guest-file-open argument @path,
even though I'm not sure you can actually get invalid input past the
QMP core there.

50761a5a9a qga: guest-get-fsinfo: add optional 'total-bytes-privileged' field
Since the commit 25b5ff1a86 ("qga: add mountpoint usage info to
GuestFilesystemInfo") we have 2 values reported in guest-get-fsinfo:
used = (f_blocks - f_bfree), total = (f_blocks - f_bfree + f_bavail) as
returned by statvfs(3).  While on Windows guests that's all we can get
with GetDiskFreeSpaceExA(), on POSIX guests we might also be interested in
total file system size, as it's visible for root user.  Let's add an
optional field 'total-bytes-privileged' to GuestFilesystemInfo struct,
which'd only be reported on POSIX and represent f_blocks value as returned
by statvfs(3).

While here, also tweak the docs to reflect better where those values
come from.

734e7b73df qga/commands-win32: Do not set matrix_lookup_t/win_10_0_t arrays size
ga_get_win_name() iterates over all elements in the arrays by
checking the 'version' field is non-NULL. Since the arrays are
guarded by a NULL terminating element, we don't need to specify
their size:

  static char *ga_get_win_name(...)
  {
      ...
      const ga_matrix_lookup_t *table = WIN_VERSION_MATRIX[tbl_idx];
      const ga_win_10_0_t *win_10_0_table = ...
      ...
      while (table->version != NULL) {
                    ^^^^^^^^^^^^^^^
              while (win_10_0_table->version != NULL) {
                                     ^^^^^^^^^^^^^^^

This will simplify maintenance when adding new entries to these
arrays.

Split WIN_VERSION_MATRIX into WIN_CLIENT_VERSION_MATRIX and
WIN_SERVER_VERSION_MATRIX because  multidimensional array must
have bounds for all dimensions except the first.

91eab32a3f qapi qga: Elide redundant has_FOO in generated C
The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with.  Recent commit "qapi: Start to

them step by step.  This is the step for qga/qapi-schema.json.

Said commit explains the transformation in more detail.  The invariant
violations mentioned there do not occur here.

g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

Windows 10 and 11 have the same major and minor versions.
So, the only way to determine the correct version is to

After this commit, the guest agent will return the proper
"version" and "version-id" for Windows 11. The "pretty-name"
is read from the registry and will be incorrect until the
MS updates the registry. We only can create some workaround
and replace 10 to 11.

Windows Server 2016, 2019, 2022 are based on Windows 10 and
have the same major and minor versions. So, the only way to
detect the proper version is to use the build number.

Before this commit, the guest agent use the last build number
for each OS, but it causes problems when new OS releases.
There are few preview versions before release, and we
can't update this list.

After this commit, the guest agent will use the first build
number. For each new preview version or release version,
Microsoft increases the build number, so we can add the number
of the first preview build and this will work until the new
OS release.

54aa3de72e qapi: Use QAPI_LIST_PREPEND() where possible
Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND().  But places where we must keep the list in order
by appending remain open-coded until later patches.

Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
 new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

This new command should allow listing information about disks of the VM

management applications for mapping virtualized devices or pass-through
devices to device names in the guest OS.

0083124b3a qga: Flatten simple union GuestDeviceId
Simple unions are simpler than flat unions in the schema, but more
complicated in C and on the QMP wire: there's extra indirection in C
and extra nesting on the wire, both pointless.  They should be avoided
in new code.

GuestDeviceId was recently added for guest-get-devices.  Convert it to
a flat union.

939caddc2c qga-win: Fix guest-get-devices error API violations
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

qmp_guest_get_devices() is wrong that way: it calls error_setg() in a
loop.

If no iteration fails, the function returns a value and sets no error.
Okay.

If exactly one iteration fails, the function returns a value and sets
an error.  Wrong.

If multiple iterations fail, the function trips error_setv()'s
assertion.

Fix it to return immediately on error.

Perhaps the failure to convert the driver version to UTF-8 should not
be an error.  We could simply not report the botched version string
instead.

Drop a superfluous continue while there.
