366d33158c python: update type hints for mypy 0.930
Mypy 0.930, released Dec 22, changes the way argparse objects are
considered. Crafting a definition that works under Python 3.6 and an
older mypy alongside newer versions simultaneously is ... difficult,
so... eh. Stub it out with an 'Any' definition to get the CI moving
again.

Oh well.

42d73f2894 Python/aqmp: fix type definitions for mypy 0.920
0.920 (Released 2021-12-15) is not entirely happy with the
way that I was defining _FutureT:

qemu/aqmp/protocol.py:601: error: Item "object" of the upper bound
"Optional[Future[Any]]" of type variable "_FutureT" has no attribute
"done"

Update it with something a little mechanically simpler that works better
across a wider array of mypy versions.

f75b20e4f1 python/aqmp: use absolute import statement
pylint's dependency astroid appears to have bugs in 2.9.1 and 2.9.2 (Dec
31 and Jan 3) that appear to erroneously expect the qemu namespace to
have an __init__.py file. astroid 2.9.3 (Jan 9) avoids that problem, but
appears to not understand a relative import within a namespace package.

Update the relative import - it was worth changing anyway, because these
packages will eventually be packaged and distributed separately.

206ce9699f qga-win: Detect Windows 11 by build number
Windows 10 and 11 have the same major and minor versions.
So, the only way to determine the correct version is to
use the build number.

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.

92857cd738 qga-win: Detect OS based on Windows 10 by first build number
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.

Commit a9431a03f7 ("target/m68k: add M68K_FEATURE_UNALIGNED_DATA feature") added
a new feature for processors from the 68020 onwards which do not require data
accesses to be word aligned.

Unfortunately the original commit missed an additional case whereby the SP is
still word aligned when setting up an additional format 1 stack frame so add the
necessary M68K_FEATURE_UNALIGNED_DATA feature guard.

0969e00b39 q800: fix segfault with invalid MacROM
"qemu-system-m68k -M q800 -bios /dev/null" crashes with a segfault
in q800_init().
This happens because the code doesn't check that rom_ptr() returned
a non-NULL pointer .

To avoid NULL pointer, don't allow 0 sized file and use bios_size with
rom_ptr().

df722e33d5 bsd-user: arm (32-bit) support
This series of patches brings in 32-bit arm support for bsd-user.  It implements
 all the bits needed to do image activation, signal handling, stack management
 and threading. This allows us to get to the "Hello World" level. The arm and x86
 code are now the same as in the bsd-user fork. For full context, the fork is at
 https://github.com/qemu-bsd-user/qemu-bsd-user/tree/blitz (though the the recent
 sig{bus,segv} needed updates are incomplete).
 
 v5 changes:
    o Moved to using the CPUArchState typedef and move
      set_sigtramp_args, get_mcontext, set_mcontext, and
      get_ucontext_sigreturn prototypes to
      bsd-user/freebsd/target_os_ucontext.h
    o Fix issues with arm's set_mcontext related to masking
      and remove an unnecessary check.
 
 We're down to only one hunk needing review:
     bsd-user/arm/target_arch_signal.c: arm set_mcontext
 
 Warnings that should be ignored:
    o make checkpatch has a couple of complaints about the comments for the
      signal trampoline, since it's a false positive IMHO.
 WARNING: Block comments use a leading /* on a separate line
