Currently, when the preallocating guest memory process fails, a not

IDs have long spread beyond QemuOpts: not everything with an ID
necessarily goes through QemuOpts. Commit 9aebf3b is about such a
case: block layer names are meant to be well-formed IDs, but some of
them don't go through QemuOpts, and thus weren't checked. The commit
fixed that the straightforward way: rename the internal QemuOpts
helper id_wellformed() to qemu_opts_id_wellformed() and give it
external linkage.
Instead of using it directly in block.c, the commit adds wrapper
bdrv_is_valid_name(), probably to hide the connection to QemuOpts.
Go one logical step further: emancipate IDs from QemuOpts. Rename the
function back to id_wellformed(), and put it in another file. While
there, clean up its value to bool. Peel off the bdrv_is_valid_name()
wrapper.
[Replaced stray return 0 with return false to match bool returns used
elsewhere in id_wellformed().

The device_name of a BlockDriverState is currently checked because it is
always used as a QemuOpts ID and qemu_opts_create() checks whether such
IDs are wellformed.
node-name is supposed to share the same namespace, but it isn't checked
currently. This patch adds explicit checks both for device_name and
node-name so that the same rules will still apply even if QemuOpts won't
be used any more at some point.
qemu-img used to use names with spaces in them, which isn't allowed any
more. Replace them with underscores.

Currently you can specify whether you want a UDP chardev backend
to be IPv4 or IPv6 using the ipv4 or ipv6 options if you use the
QemuOpts parsing code in inet_dgram_opts(). However the QMP struct
parsing code in socket_dgram() doesn't provide this flexibility
(which in turn prevents us from converting the UDP backend handling
to the new style QAPI framework).
Use the existing inet_addr_to_opts() function to convert the
remote->inet address to option strings; this handles ipv4 and
ipv6 flags as well as host and port. (It will also convert any
'to' specification, which is harmless as it is ignored in this
context.)

The current implementation depends on a configure-time generated list of
block modules. When any of them is absent, module_load() emits a warning.
This is suboptimal because extracting code to modules was mainly done to
allow separate packaging of modules with intrusive dependencies. Absence
of optional packages then leads to absence of modules and an error
message, which users may recognize as new and report as error.

The problem is apparently in the qemu_opts_append(). Well, if it
gets called twice or more. On the first call, when @dst is NULL
some initialization is done during which @dst->head list gets
initialized. The list is initialized in a way, so that the list
tail points at the list head. However, the next time
qemu_opts_append() is called for new options to be added,
g_realloc() may move @dst to a new address making the old list tail
point at an invalid address. If that's the case, we must update the
list pointers.

This patch adds the table implementation of the Advanced Encryption Standard (AES)
InvMixColumns transformation.
The patch is intentionally asymmetrical -- the MixColumns table is not added because

Now only qemu_opts_append uses 'allocated' to indicate free memory.
For this function only, we can also let result list's (const char *)
members point to input list's members, only if the input list has
longer lifetime than result list. In current code, that is true.
So, we can remove the 'allocated' member from QemuOptsList definition
to keep code clean.

Add qemu_opt_get_del, qemu_opt_get_bool_del, qemu_opt_get_number_del and
qemu_opt_get_size_del to replace the same handling of QEMUOptionParameter
(get and delete).
Several drivers are coded to parse a known subset of options, then
remove them from the list before handing all remaining options to a
second driver for further option processing. get_*_del makes it easier
to retrieve a known option (or its default) and remove it from the list
all in one action.
Share common helper function:
For qemu_opt_get_bool/size/number, they and their get_*_del counterpart
could share most of the code except whether or not deleting the opt from
option list, so generate common helper functions.
For qemu_opt_get and qemu_opt_get_del, keep code duplication, since
1. qemu_opt_get_del returns malloc'd memory while qemu_opt_get returns
in-place memory
2. qemu_opt_get_del returns (char *), qemu_opt_get returns (const char *),
and could not change to (char *), since in one case, it will return
desc->def_value_str, which is (const char *).

qemu_opt_del() already assumes that all QemuOpt instances contain

opts_start_struct() was doing its own thing and using static storage

Block I/O throttling uses timers and currently always adds them to the
main loop. Throttling will break if bdrv_set_aio_context() is used to
move a BlockDriverState to a different AioContext.
This patch adds throttle_detach/attach_aio_context() interfaces so the
throttling timers and uses them to move timers to the new AioContext.
Note that bdrv_set_aio_context() already drains all requests so we're
sure no throttled requests are pending.
The test cases need to be updated since the throttle_init() interface
has changed.

g_poll has a problem on Windows when using
timeouts < 10ms, in glib/gpoll.c:
/* If not, and we have a significant timeout, poll again with
* timeout then. Note that this will return indication for only
* one event, or only for messages. We ignore timeouts less than
* ten milliseconds as they are mostly pointless on Windows, the
* MsgWaitForMultipleObjectsEx() call will timeout right away
* anyway.
*/
if (retval == 0 && (timeout == INFINITE || timeout >= 10))
retval = poll_rest (poll_msgs, handles, nhandles, fds, nfds, timeout);
so whenever g_poll is called with timeout < 10ms it does
a quick poll instead of wait, this causes significant performance
degradation of QEMU, thus we should use WaitForMultipleObjectsEx
directly

Using error_is_set(ERRP) to find out whether to bail out due to
previous error is either wrong, fragile, or unnecessarily opaque.
It's wrong when ERRP may be null, because errors go undetected when it
is. It's fragile when proving ERRP non-null involves a non-local
argument. Else, it's unnecessarily opaque (see commit 84d18f0).
The error_is_set(state->errp) in qemu_opts_from_qdict_1() is merely
fragile, because the callers never pass state argument with null
state->errp.
Make the code more robust and more obviously correct: test
*state->errp directly.

glib versions prior to 2.31.0 require an explicit g_thread_init() call
to enable multi-threading.
Failure to initialize threading causes glib to take single-threaded code
paths without synchronization. For example, the g_slice allocator will
crash due to race conditions.
Fix this for all QEMU tool programs (qemu-nbd, qemu-io, qemu-img) by
moving the g_thread_init() call from vl.c:main() into a new
osdep.c:thread_init() constructor function.
thread_init() has __attribute__((constructor)) and is automatically
invoked by the runtime during startup.
We can now drop the "simple" trace backend's g_thread_init() call since
thread_init() already called it.
Note that we must keep coroutine-gthread.c's g_thread_init() call which
is located in a constructor function. There is no guarantee for
constructor function ordering so thread_init() may only be called later.

QemuMutex does not guarantee fairness and cannot be acquired
recursively:
Fairness means each locker gets a turn and the scheduler cannot cause
starvation.
Recursive locking is useful for composition, it allows a sequence of
locking operations to be invoked atomically by acquiring the lock around
them.
This patch adds RFifoLock, a recursive lock that guarantees FIFO order.
Its first user is added in the next patch.
RFifoLock has one additional feature: it can be initialized with an
optional contention callback. The callback is invoked whenever a thread
must wait for the lock. For example, it can be used to poke the current
owner so that they release the lock soon.

This patch adds the Divide Doubleword Extended instructions.
The implementation builds on the unsigned helper provided in
the previous patch.

This patch adds the Divide Doubleword Extended Unsigned
instructions. This instruction requires dividing a 128-bit
value by a 64 bit value. Since 128 bit integer division is
not supported in TCG, a helper is used. An architecture
independent 128-bit division routine is added to host-utils.

gmodule-2.0's pkg-config files include -Wl,--export-dynamic, which breaks
static builds. It is a glib bug, but we need to support --static builds for
the linux-user targets, and in the end all that is needed to fix this is:
* outlaw --enable-modules --static, which makes little sense anyway
* only include gmodule-2.0's cflags and ldflags if --enable-modules is
specified on the command line.
