* Introduces qemu_fopen, qemu_access wrappers, and modifies qemu_open to
support converting stored UTF-8 paths to UTF-16 to use Unicode
filesystem API on Windows platform.
* Migrates several native open, fopen, and access calls to their
qemu_* counterparts to resolve Unicode path handling issues on
Windows.
When adding RAM_NORESERVE, we forgot to remove the old assertion when
adding the updated one, most probably when reworking the patches or
rebasing. We can easily crash QEMU by adding
-object memory-backend-ram,id=mem0,size=500G,reserve=off
to the QEMU cmdline:
qemu-system-x86_64: ../softmmu/physmem.c:2146: qemu_ram_alloc_internal:
Assertion `(ram_flags & ~(RAM_SHARED | RAM_RESIZEABLE | RAM_PREALLOC))
== 0' failed.
Fix it by removing the old assertion.

Commit 1e63fe6858 ("machine: pass QAPI struct to mc->smp_parse")
introduced documentation stating that a zero input value for an SMP
parameter indicates that its value should be automatically configured.
This is indeed how things work today, but we'd like to change that.
Avoid documenting behaviors we want to leave undefined for the time
being, giving us freedom to change it later.

machine_set_smp() mistakenly checks 'errp' not '*errp',
and so thinks there is an error every single time it runs.
This causes it to jump to the end of the method, skipping
the max CPUs checks. The caller meanwhile sees no error
and so carries on execution. The result of all this is:
$ qemu-system-x86_64 -smp -1
qemu-system-x86_64: GLib: ../glib/gmem.c:142: failed to allocate 481036337048 bytes
instead of
$ qemu-system-x86_64 -smp -1
qemu-system-x86_64: Invalid SMP CPUs -1. The max CPUs supported by machine 'pc-i440fx-6.1' is 255
This is a regression from

On oss-fuzz, we build twice, to put together a build that is portable to
the runner containers. On gitlab ci, this is wasteful and contributes to
timeouts on the build-oss-fuzz job. Avoid building twice on gitlab, at
the remote cost of potentially missing some cases that break oss-fuzz
builds.

The windows cross builds still take way too long in gitlab CI, so need
more targets to be skipped. We don't want to hurt coverage of other
cross builds more though, so we let jobs fine tune with a new env
variale $CROSS_SKIP_TARGETS.
We take the set of targets that are considered relatively niche or
very old architectures, and skip approx half of them in win32 builds
and the other half of them in win64.
