Now that shutdown() is guaranteed to always execute self._load_io_log()
and self._post_shutdown(), their calls in 'except' became redundant and
we can safely replace it by a call to shutdown().

The 'returncode' Popen attribute is not guaranteed to be updated. It
actually depends on a call to either poll(), wait() or communicate().
On the other hand, poll() will: "Check if child process has terminated.
Set and return returncode attribute."
Let's use the poll() to check whether the process is running and to get
the updated process exit code, when the process is finished.

To make sure we will always cleanup, this patch makes the

To launch a VM, we need to create basically two files: the monitor
socket (if it's a UNIX socket) and the qemu log file.
For the qemu log file, we currently just open the path, which will
create the file if it does not exist or overwrite the file if it does
exist.
For the monitor socket, if it already exists, we are currently removing
it, even if it's not created by us.
This patch moves to _pre_launch() the responsibility to create a
temporary directory to host the files so we can remove the whole
directory on _post_shutdown().

Python2 did not validate locale correctness when reading input data, so
would happily read UTF-8 data in non-UTF-8 locales. Python3 is strict so
if you try to read UTF-8 data in the C locale, it will raise an error
for any UTF-8 bytes that aren't representable in 7-bit ascii encoding.
e.g.
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 54: ordinal not in range(128)

More background on this can be seen in

Many distros support a new C.UTF-8 locale that is like the C locale,
but with UTF-8 instead of 7-bit ASCII. That is not entirely portable
though. This patch thus sets the LANG to "C", but overrides LC_CTYPE
to be en_US.UTF-8 locale. This gets us pretty close to C.UTF-8, but
in a way that should be portable to everywhere QEMU builds.
This patch only forces UTF-8 for QAPI scripts, since that is the one
showing the immediate error under Python3 with C locale, but potentially
we ought to force this for all python scripts used in the build process.

The inet_parse() function looks for 'ipv4' and 'ipv6' flags, but only
treats them as bare bool flags. The normal QemuOpts parsing would allow
on/off values to be set too.
This updates inet_parse() so that its handling of the 'ipv4' and 'ipv6'
flags matches that done by QemuOpts.
This impacts the NBD block driver parsing the legacy filename syntax and
the migration code parsing the socket scheme.

The memory-internal.h header claims that it is for "obsolete
exec.c functions" which "will be removed soon". This statement
was added in 2011, six years ago, but the header is still here.
(Admittedly none of the prototypes added in commit 67d95c153b
are still in the header.)
It's convenient to have a place to put prototypes for functions
which are used internally to the various .c files of the memory
system or by the accel/tcg code, which is inevitably fairly
closely coupled. So keep the header but update the comments to
reflect what we're actually using it for.

Completion strings are not persistent accross completions (why would
they?). They are allocated under readline_completion(), which already

The idea is to send a victim request that will possibly block in the
server and to send a flush request to cancel the victim request.
This patch adds two test to verifiy that:
- the server does not reply to a victim request that was actually
cancelled
- the server replies to the flush request after replying to the
victim request if it could not cancel it
9p request cancellation reference:
