This changes the failure from:

to:

bf5de8c5d6 qmp: 'add_client' actually expects sockets 
Whether it is SPICE, VNC, D-Bus, or the socket chardev, they all
actually expect a socket kind or will fail in different ways at runtime.

Throw an error early if the given 'add_client' fd is not a socket, and
close it to avoid leaks.

This allows to replace the close() call with a more correct & portable
closesocket() version.

(this will allow importing sockets on Windows with a specialized command
in the following patch, while keeping the remaining monitor associated
sockets/add_client code & usage untouched)

abe34282b0 win32: avoid mixing SOCKET and file descriptor space 
Until now, a win32 SOCKET handle is often cast to an int file
descriptor, as this is what other OS use for sockets. When necessary,
QEMU eventually queries whether it's a socket with the help of
fd_is_socket(). However, there is no guarantee of conflict between the
fd and SOCKET space. Such conflict would have surprising consequences,
we shouldn't mix them.

Also, it is often forgotten that SOCKET must be closed with
closesocket(), and not close().

Instead, let's make the win32 socket wrapper functions return and take a
file descriptor, and let util/ wrappers do the fd/SOCKET conversion as
necessary. A bit of adaptation is necessary in io/ as well.

Unfortunately, we can't drop closesocket() usage, despite
_open_osfhandle() documentation claiming transfer of ownership, testing
shows bad behaviour if you forget to call closesocket().

d4f784c51b gitlab-ci.d/buildtest: Rework the target list of build-system-alpine 
The target list of the build-system-alpine job is pretty much a copy
of the build-system-ubuntu job (apart from "aarch64-softmmu" which
has recently been removed from the ubuntu job in commit 6eda5ef5f8,
but aarch64-softmmu is still also tested in the opensuse jobs, so
we don't need to keep it here).

Let's stop wasting our CI minutes with such duplications, and focus
on testing targets instead that do not have such a great test coverage
yet: The "loongarch64-softmmu" target has never been added to our
build tests yet since it has been introduced, and the "mips64-softmmu"
target is so far only tested in jobs that lack the "avocado" testing
stage (only the little endian or 32-bit MIPS variants are tested in
jobs with avocado so far).

While we're at it, also move the avr-softmmu and mipsel-softmmu targets
from the Debian job to the alpine job, since the Debian job (and its
following test jobs) has already a long runtime compared to the others
jobs. With this movement, the runtimes should be more equally distributed
along the parallel running jobs now.

1bfc8dde50 tests/migration: Tweek auto converge limits check 
Thomas found an autoconverge test failure where the

To try and avoid this again:
  a) Reduce the usleep in test_migrate_auto_converge
    so that it should exit quicker when autoconverge kicks in
  b) Make the loop exit immediately rather than have the sleep
     when it does start autoconverge, otherwise the autoconverge
     might succeed during the sleep.
  c) Reduce inc_pct so auto converge happens more slowly
  d) Reduce the max-bandwidth in migrate_ensure_non_converge
    to make the ensure more ensure.

On linux user mode, CPUX86State::gdt::base from Different CPUX86State
Objects have same value, It is incorrect! Every CPUX86State::gdt::base
Must points to independent memory space.

Raise SIGFPE for ieee exceptions.

The other types, such as FSR_FTT_UNIMPFPOP, should not appear,
because we enable normal emulation of missing insns at the
start of sparc_cpu_realizefn().

c47d7c87bf linux-user/sparc: Handle coprocessor disabled trap 
Since qemu does not implement a sparc coprocessor, all such
instructions raise this trap.  Because of that, we never raise
the coprocessor exception trap, which would be vector 0x28.

97ff1478d2 linux-user/sparc: Handle priviledged opcode trap 
For the most part priviledged opcodes are ifdefed out of the
user-only sparc translator, which will then incorrectly produce
illegal opcode traps.  But there are some code paths that
properly raise TT_PRIV_INSN, so we must handle it.
