* Limit Pentium 3 CPUID to leaf 2
* Clear EBX for leaf 1

* 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.
