537c8e5e24 meson: fix cpuset_getaffinity() detection
The cpuset_getaffinity() function is checked in sys/cpuset.h to see if
BSD CPU affinity APIs are available. This check requires including
sys/param.h to work properly, otherwise the test program fails with
unrelated errors like:

/usr/include/sys/cpuset.h:155:1: error: unknown type name
'__BEGIN_DECLS'
__BEGIN_DECLS
^
/usr/include/sys/cpuset.h:156:12: error: unknown type name 'cpusetid_t';
did you mean 'cpuset_t'?
int     cpuset(cpusetid_t *);

and so forth.

c7edcb320b ci: run a mingw64 job on stable Fedora
Both of the current mingw jobs are marked as 'allow_failure' because
they are running against Fedora rawhide which is an unstable distro.

We need at least one mingw job to be gating to more reliably detect
problems.

This introduces dockerfiles for both mingw variants on Fedora 35
and sets the mingw64 build to run on Fedora 34, and mingw32 on
Fedora rawhide.

0ac13b189f virsh: Do not try connecting first time without polkit agent
Trying to connect once without a polkit agent will generate an error on the
server side which seems too rough given it only serves the purpose of the client
(virsh in this case) to figure out that an agent is needed.  Thankfully we can
just try running the agent.  It does not break anything as we are running it
with `--fallback`, which makes sure it does not replace an existing agent in
case there is one already registered.

The second piece of code trying to start the polkit text agent is kept in order
to _really_ try out starting the agent (and error out when failing to do so)
just in case the agent was not available the first time it was ran.  Even though
it should not happen it avoids a very rare race condition and really does not
add much complexity.

c07cf0a686 meson: improve CPU affinity routines check
Recently, FreeBSD has got sched_get/setaffinity(3) implementations and
the sched.h header as well [1]. To make these routines visible,
users have to define _WITH_CPU_SET_T.

This breaks current detection. Specifically, meson sees the
sched_getaffinity() symbol and defines WITH_SCHED_GETAFFINITY. This
define unlocks Linux implementation of virProcessSetAffinity() and other
functions, which fails to build on FreeBSD because cpu_set_t is not
visible as _WITH_CPU_SET_T is not defined.

For now, change detection to the following:

 - Instead of checking sched_getaffinity(), check if 'cpu_set_t' is
   available through sched.h
 - Explicitly check the sched.h header instead of assuming its presence
   if WITH_SCHED_SETSCHEDULER is defined

treated as arguments of machine itself.

The -accel argument was introduced in QEMU commit
v2.9.0-rc0~70^2~19 and since our minimum required version is
newer (2.11.0) we can safely assume its existence and use it
without any capability.

3010a69226 qemu_command: Generate -mem-prealloc in one corner case more
When guest has NUMA nodes and QEMU is new enough to report
default RAM ID then ideally we would use -numa memdev= combined
with memory-backend-* combo becasue -mem-path/-mem-prealloc/-numa
mem are deprecated. Well, there is one problem - the .memdev=
attribute is machine type dependent (just look at arguments of
virQEMUCapsGetMachineNumaMemSupported()) and to ensure backwards
compatibility we prefer -numa mem= over -numa memdev=.

But there was one corner case when -mem-prealloc was requested
but not generated on the cmd line. It all starts with
qemuBuildMemCommandLine() which generates just '-m XXX' and
because it sees defaultRAMid and guest NUMA nodes greater than
zero it does nothing more.

Then, qemuBuildNumaCommandLine() sees that -numa mem= is still
supported for given machine type and nothing else set
@needBackend thus qemuBuildMemPathStr() is called which output
-mem-prealloc only in a few cases assuming it was outputted
earlier.
