Implement pthread_attr_setcreatesuspend_np, pthread_resume_np,
pthread_resume_all_np and pthread_multi_np with the sce forms
scePthreadAttrSetcreatesuspend, scePthreadResume, scePthreadResumeAll
and scePthreadMulti, following FreeBSD 11.4 libthr and the firmware
13.42 libkernel_sys module. A thread created suspended waits before its
start routine, outside any cancellation point, until it is resumed.
sceKernelRaiseException throws on Windows for a thread still suspended
at creation.
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.

The PS5 3.20 export lists have swapcontext in libkernel as well as
libkernel_sys, and on Windows a libkernel import never reaches
libkernel_sys. The assembly entry in UserContext.cpp now is
swapcontext_nid_postfix, and the libkernel_sys jump stub is gone.
On Windows, mkdirat with a directory descriptor and a relative path that goes through a symbolic link pointing to itself reported EIO. CreateDirectoryW fails with ERROR_CANT_RESOLVE_FILENAME for such a path, and the error mapping had no case for it, so it fell through to GuestEio. FreeBSD fails the lookup with ELOOP. The path form of mkdir and openat with the same descriptor already return ELOOP. ERROR_CANT_RESOLVE_FILENAME now gives ELOOP.
guest_kernel_sys gains a Windows check with a file-type and a directory-type self-loop: mkdirat through the loop returns ELOOP and mkdirat of the link itself still returns EEXIST. The check is skipped when the host denies symbolic link creation.
kern_fpathconf answers _PC_ASYNC_IO with _POSIX_ASYNCHRONOUS_IO (200112) after the descriptor lookup, and a pipe or socket (no vnode) with PIPE_BUF for _PC_PIPE_BUF and EINVAL for every other name. Drop the unused File.hpp include and the duplicate KernelErrors.hpp include.

DescriptorIsOpen_nid_no_patch is not extern "C", so the patched libkernel.prx
does not export it and libkernel_sys.prx fails to load (patched_libraries:
LoadLibraryEx error 127). Check the descriptor like fchown does: GuestFstat on
Windows, fstat elsewhere, EBADF on failure.

sceKernelGetSystemExVersion, sysKernelGetLowerLimitSysexVersion,
sysKernelGetLowerLimitUpdVersion and sceKernelGetTraceMemoryStats were
NotImplemented stubs in libkernel_sys. libkernel, libkernel_sys and
libkernel_web of firmware 13.42 answer them without asking the kernel:
empty strings, a zero version and zero statistics, with the null checks
and return codes the firmware uses, including the plain 22 of
sceKernelGetSystemExVersion.
