lchflags is chflags without following a symbolic link in the last path
component, as FreeBSD 11.4's sys_lchflags calls kern_chflagsat with
AT_SYMLINK_NOFOLLOW. chflags now goes through a shared helper that takes
the follow choice; a link in the last component is accepted as the
target when not following, and the flag checks are unchanged.

Prospero Win measured on firmware 12.02 that the PS5 kernel accepts
MAP_EXCL but ignores it: MAP_FIXED | MAP_EXCL over an existing mapping
replaces it without error. Fixed anonymous mmap now does the same instead
of FreeBSD's ENOMEM. MAP_EXCL without MAP_FIXED stays EINVAL.

Match the AT_REMOVEDIR and rmdir sites so file reparse points stay on the old unlink path. Cover file symlink unlinkat on Windows and point the debt at the drive-target consumers.
rmdir followed the junction and reported ENOTEMPTY, and unlink treated it as a real directory, so a junction to a non-empty folder could not be removed.
Main's #9573 implements scePthreadResume right after the
scePthreadMutexattrSetkind stub this branch removes from libkernel_sys;
the merge takes main's scePthreadResume and leaves the stub out.
Main's public-header audit wants one header declaration per export, so
the merge declares this branch's scePthreadMutexattrSetkind,
scePthreadMutexattrGetkind and pthread_rwlockattr_settype_np in
libkernel's Api.hpp, drops their stub declarations from libkernel_sys's
Api.hpp, has Mutex.cpp take sceKernelError from libkernel's Api.hpp,
and has the test include the libkernel headers instead of its own
declarations.
On PS5 firmware 13.60 setpriority(PRIO_PROCESS, 0, v) returns 0 for -25,
-5, 5 and 25, and getpriority keeps returning 0. setpriority keeps its
target checks and returns 0 without storing the value.

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.
A handler that read the mask and put it back with SIG_SETMASK stored its
own signal, which sigprocmask reports from the hold, in the process mask
and cleared the hold, so the signal stayed blocked after the handler
returned. pselect, setcontext and a siglongjmp inside the handler replace
the mask the same way. When the handler's own thread releases a hold, the
signal now gets back its bit from before the handler when the handler
returns, as FreeBSD's sigreturn puts back the mask from before it. A mask
another thread sets meanwhile is kept.
FreeBSD's F_SETFL may change O_FSYNC (FCNTLFLAGS), and vn_write then
writes with IO_SYNC. The flag now lives in the status table, and the
write entry points sync a regular file after the write while it is set.
