coroutine-win32.c: Add noinline attribute to work around gcc bug
A gcc codegen bug in x86_64-w64-mingw32-gcc (GCC) 4.6.3 means that
non-debug builds of QEMU for Windows tend to assert when using
coroutines. Work around this by marking qemu_coroutine_switch
as noinline.
If we allow gcc to inline qemu_coroutine_switch into
coroutine_trampoline, then it hoists the code to get the
address of the TLS variable "current" out of the while() loop.
This is an invalid transformation because the SwitchToFiber()
call may be called when running thread A but return in thread B,
and so we might be in a different thread context each time
round the loop. This can happen quite often. Typically.
a coroutine is started when a VCPU thread does bdrv_aio_readv:
VCPU thread
main VCPU thread coroutine I/O coroutine
bdrv_aio_readv ----->
start I/O operation
thread_pool_submit_co
<------------ yields
back to emulation
Then I/O finishes and the thread-pool.c event notifier triggers in
the I/O thread. event_notifier_ready calls thread_pool_co_cb, and
the I/O coroutine now restarts *in another thread*:
iothread
main iothread coroutine I/O coroutine (formerly in VCPU thread)
event_notifier_ready
thread_pool_co_cb -----> current = I/O coroutine;
call AIO callback
But on Win32, because of the bug, the "current" being set here the
current coroutine of the VCPU thread, not the iothread.
noinline is a good-enough workaround, and quite unlikely to break in
the future.

and providing the detailed example/ascii art quoted above.)

target-i386: Set migratable=yes by default on "host" CPU mooel
Having only migratable flags reported by default on the "host" CPU model
is safer for the following reasons:
* Existing users may expect "-cpu host" to be migration-safe, if they
take care of always using compatible host CPUs, host kernels, and
QEMU versions.
* Users who don't care aboug migration and want to enable all features
supported by the host kernel can simply change their setup to use
migratable=no.
Without this change, people using "-cpu host" will stop being able to
migrate, because now "invtsc" is getting enabled by default.
We are not setting migratable=yes by default on all X86CPU subclasses,
because users should be able to get non-migratable features enabled if
they ask for them explicitly.
target-i386: Add "migratable" property to "host" CPU model
This flag will allow the user to choose between two modes:
* All flags that can be enabled on the host, even if unmigratable
(migratable=no);
* All flags that can be enabled on the host, are known to QEMU
and migratable (migratable=yes).
The default is still migratable=false, to keep current behavior, but
this will be changed to migratable=true by another patch.
My plan was to support the "migratable" flag on all CPU classes, but
have the default to "false" on all CPU models except "host". However,
DeviceClass has no mechanism to allow a child class to have a different
property default from the parent class yet, so by now only the "host"
CPU model will support the "migratable" flag.

KVM never supported the MONITOR flag so it doesn't make sense to have it

The rationale here is similar to the cases where it makes sense to have
a feature enabled by default on all CPU models when on KVM mode (e.g.
x2apic). In this case we are having a feature disabled by default for
the same reasons.
In this case we don't need machine-type compat code because it is
currently impossible to run a KVM VM with the MONITOR flag set.

monitor: protect event emission
Event emission must be protected by a mutex because of access to
the shared rate-limiting state, and to guard against concurrent
monitor "hot-plug" by means of human-monitor-command.

qemu-char: make writes thread-safe
This will let threads other than the I/O thread raise QMP events.
GIOChannel is thread-safe, and send and receive state is usually
well-separated. The only driver that requires some care is the
pty driver, where some of the state is shared by the read and write
sides. That state is protected with the chr_write_lock too.

qapi event: convert SPICE events
SPICE_INITIALIZED, SPICE_CONNECTED, SPICE_DISCONNECTED and
SPICE_MIGRATE_COMPLETED are converted in one patch, since they
use some common functions. inet_strfamily() is removed since no
callers exist anymore.
Note that there is no existing doc for SPICE_MIGRATE_COMPLETED
in docs/qmp/qmp-events.txt before this patch.

qapi event: convert other BLOCK_JOB events
Since BLOCK_JOB_COMPLETED, BLOCK_JOB_CANCELLED, BLOCK_JOB_READY are
related, convert them in one patch. The block_job_event_* functions
are used to keep encapsulation of BlockJob structure.
