Emanueleandmugurc 190ed6c8fb feat(libkernel): guest memory protection and VirtualQuery on macOS hosts 
- mprotect: the guest rounds a range to its 16 KiB pages. A Mach-O image
  is loaded at a multiple of the host page size only (4 KiB under
  Rosetta), so the pages are counted from where the ELF address 0 of the
  image holding the range was loaded, and a rounded edge smaller than a
  guest page that lies in the gap between two segments, where no host page
  exists, is left out. The write watch is told the new protection.
- sceKernelVirtualQuery reads the region with mach_vm_region.
- sceKernelMunlockall unlocks the ranges libkernel locked, one by one:
  macOS has no munlockall, which fails there with ENOSYS and would
  overwrite errno.
- The stack protect test reads page protections with mach_vm_region.

This is mugurc's f66a4df741 from his macOS series, without the mlock
check that #10889 adds.

011010 9e23a9263c fix(libkernel): report urgent data in poll on macOS 
XNU's poll never reports POLLPRI for out-of-band data, so a guest poll
that asks for it never sees the urgent byte: guest_poll aborts at the
OOB case and a title waiting on priority data would sleep to its
timeout.

On macOS the pending byte is read from SIOCATMARK, which reports it
without consuming it and has no descriptor limit, unlike the fd_set
probe this replaces. POLLRDBAND is set with POLLPRI as FreeBSD 11.4's
sopoll_generic does, and the wait takes the sliced path main already
uses for a kqueue wait, so it wakes on the next slice instead of at the
deadline.

recv(MSG_OOB | MSG_PEEK) was measured to consume the byte on macOS
27.0.1 and kevent with NOTE_OOB does not fire there, which is why the
probe is SIOCATMARK. The select and libSceNet poll paths still miss
urgent data on macOS and are recorded in the debt entry.
