AppKit, which SDL uses for windows, Metal surfaces, event pumping and game
controllers, works only on the main thread, and a guest never hands its
thread back. The macOS relinker emits a call to Aps5StartGuest as the
entry of a relinked executable; no library provided it.
- Aps5StartGuest runs the guest entry on a new thread with the stack size
of the main thread (at least 8 MiB) and serves the main dispatch queue
from the run loop of the main thread. The guest ends the process with
exit; a guest entry that returns aborts.
- Aps5RunOnMainThread runs a function on the main thread and waits for it,
or in place where the main thread is the caller or Aps5StartGuest was
never called.
- libSceVideoOut sends its SDL calls through OnMainThread, which carries
the exceptions back to the caller: the initialisation and shutdown of the
video and game controller subsystems, the window, its Vulkan surface and
drawable size, the event polling and the pad, mouse and keyboard input,
which are created and destroyed there. On the other platforms the
functions run in place.
- The flip test starts its tests through Aps5StartGuest on macOS, as a
relinked guest does.

On PS5 firmware 13.60 pthread_mutex_setyieldloops_np and
scePthreadMutexSetyieldloops return EINVAL on a destroyed mutex, as the
other spin and yield loop calls already did here. The default counts
(2000 spins for an adaptive mutex, 0 otherwise, 0 yields) match.

On PS5 firmware 13.60 sceKernelGetEventError returns 0x80020000 plus the
event's fflags in 32 bits for every non-zero fflags, including values
above 0xFFFF, where it used to throw.

On PS5 firmware 13.60 sceKernelGetProsperoSystemSwVersion and
sceKernelGetSystemSwVersion return 0 for every value in the leading size
field, keep it, write the string and the packed version, and return 0
without writing for a null block.

Main's #10706 moves the declarations of exported functions and their types
into the libraries' public headers, and gives WaitForPendingInSet a
KernelTimespec timeout. The merge keeps this branch's DeliverUnblockedPending
and ChangeBlockedMask with main's KernelTimespec. It takes main's side of
the declarations in GuestSignalSets.cpp, whose setjmp and longjmp this
branch had added and libc's Api.hpp now declares. GuestSignalHandlerMask.cpp
includes the libkernel and libc public headers in place of its own
declarations and GuestSignalSet and GuestSigaction types, as the
public_headers audit requires.
FreeBSD 11.4's kern_settimeofday rejects a timeval with a microsecond
field outside 0 to 999999 or a negative second field with EINVAL before
changing anything, sets the clock from a valid timeval, and then stores
the timezone, which gettimeofday reports. settimeofday now checks the
timeval the same way and throws for a valid one, as clock_settime does,
because the host clock is not changed. A timezone given without a
timeval is stored and gettimeofday reports it instead of 0 and 0.

Main extends the libkernel debt entry on libSceNet sockets with poll and
fcntl, where this branch adds getsockopt to the same entry; the merge keeps
both.
Source Port (PPSA20040) checks whether a debugger is attached with
sysctl {CTL_KERN, KERN_PROC, KERN_PROC_PID, getpid()} into a 1,088-byte
buffer and tests P_TRACED (0x800) in ki_flag at offset 0x170; the MIB was
unsupported, so the title threw at start-up. Return a FreeBSD 11 amd64
kinfo_proc for the calling process with ki_structsize, ki_pid, ki_ppid and
ki_comm filled and every other field 0, so P_TRACED is clear. Like
kern.proc.vmmap, any other pid fails with ESRCH, a write with EPERM and a
short buffer with ENOMEM. The rest of the record is not measured on a
console and is recorded as debt.
Main's #10706 declares getsockopt_nid_postfix and sceNetGetsockopt in the libraries' public headers, so this branch's local declarations of them in GuestSceNet.cpp and libSceNet's Export.cpp go.
Resolve a FreeBSD/ELF tls_index {module, offset} the way the relinker's
DTPMOD64 values are laid out: on Windows through the PE _tls_index the
module word points at and the thread's ThreadLocalStoragePointer, on
Linux through glibc's __tls_get_addr.
