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.

link took the source's std::filesystem::status first, and MinGW-w64's
libstdc++ reports a Windows symbolic link loop as not found (ENOENT), so
it returned ENOENT before FollowLinkPath, which maps the loop's
ERROR_CANT_RESOLVE_FILENAME to ELOOP, was reached. guest_kernel_sys's
loop case failed at that check wherever symbolic links can be created
(Windows 11 22H2: "check failed at line 835 (guest errno 2)").
When the status reports the source missing, ask FollowLinkPath first:
a loop now returns ELOOP and a dangling link still ENOENT; a missing
path is unchanged.

Read the clock of a libkernel condition attribute, returning
SCE_KERNEL_ERROR_EINVAL for a null or destroyed attribute as
scePthreadCondattrSetclock does, after FreeBSD 11.4 libthr's
_pthread_condattr_getclock. A null clock pointer throws.
All four exports threw. The ownership calls follow fchown: owner and
group 0 and the unchanged value are accepted and any other value
throws. The path is looked up first with stat, lstat or fstatat, as
FreeBSD 11's kern_fchownat does, so a lookup error is returned before
the owner is checked. fchownat rejects flags other than
AT_SYMLINK_NOFOLLOW with EINVAL. linkat passes AT_FDCWD and absolute
paths to link and rejects flags other than AT_SYMLINK_FOLLOW with
EINVAL; a relative path with a directory descriptor and a symbolic
link source without AT_SYMLINK_FOLLOW throw. On Windows a symbolic
link source is detected with the file attributes, since libstdc++
there reports it as a regular file.

The EINVAL for a descriptor without a vnode now applies only to a pipe or socket. A character device is a vnode on FreeBSD, so getvnode succeeds and change_dir fails with ENOTDIR; File::IsCharacterDevice keeps that answer for the host character devices (a tty, NUL or /dev/null) and the guest random device. guest_kernel_sys pins it with /dev/random.

FreeBSD 11.4's sys_fchdir resolves the descriptor with getvnode, which fails with EINVAL for a descriptor that has no vnode; only a vnode that is not a directory gives ENOTDIR from change_dir. fchdir returned ENOTDIR for a pipe or socket. A descriptor that is neither a vnode nor a random device now gets EINVAL; the debt entry records the order of the three errors.

Forward scePthreadBarrier*, scePthreadBarrierattr*, scePthreadGetcpuclockid,
scePthreadGetconcurrency and sceKernelMsync to libkernel's POSIX
implementations and return POSIX errors as SCE kernel errors.

The PS5 3.20 export lists have pselect in libkernel as well as
libkernel_sys, and on Windows a libkernel import never reaches
libkernel_sys. The implementation moves unchanged to
libkernel/Socket/src/Pselect.cpp, beside select.
The PS5 3.20 export lists have ktimer_* in libkernel as well as
libkernel_sys, and on Windows a libkernel import never reaches
libkernel_sys. The implementation moves unchanged to
libkernel/Time/Ktimer.cpp.
Resolves the conflict with #8522 in link_nid_postfix: keep its ENOTDIR
return for a destination below a regular file and the Windows
symbolic-link follow after it.
