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 clock id with CPUCLOCK_PROCESS_BIT threw in clock_gettime and
clock_getres. FreeBSD 11 get_cputime reads the process's CPU time, or
fails with EINVAL when pget finds no such process, and kern_clock_getres
gives every CPU clock the CPU time resolution without a lookup. The
guest's own process clock now reads CLOCK_PROCESS_CPUTIME_ID, any other
fails with EINVAL, as kill already finds no other process.
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.
Main's #9618 has lstat fill a local FileStat and copy it out to the guest.
The merge keeps that and this branch's module lookup in the same call, so an
original .prx name still resolves to its relinked .guest.prx.
sceKernelGetTscFrequency times 20 ms of TSC ticks against the monotonic
clock. A thread that moves to another CPU during the sleep reads its end
value from another TSC. Where the TSCs of the CPUs differ, as on a Windows
VM whose vCPU 0 counts about 3.8 billion ticks ahead of the others, the
frequency came out as 0 or as 180 GHz. Pin the calibrating thread to the
CPU it runs on and restore its affinity afterwards.

The public header declared the unimplemented placeholder int __tls_get_addr(void). It now declares void* __tls_get_addr(const KernelTlsIndex*), the tls_index pointer the ABI passes, and the implementation and the test use that declaration and type instead of their own.
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.
scePthreadMutexTimedlock on a mutex the caller holds, and
scePthreadRwlockTimedrdlock and scePthreadRwlockTimedwrlock on a rwlock
it holds for writing, returned EDEADLK at once. The console returns
ETIMEDOUT, as the prosper console oracle measured. They now sleep until
the timeout and return ETIMEDOUT, as FreeBSD libthr does. The POSIX
timed locks call these and change with them.

fcntl(fd, F_DUPFD, min) with min at or above RLIMIT_NOFILE duplicated the
descriptor repeatedly until the CRT table was full and then failed with
EMFILE, after opening thousands of descriptors. FreeBSD checks the minimum
first: kern_dup returns EINVAL for FDDUP_FCNTL when new < 0 or
new >= maxfd (sys/kern/kern_descrip.c:836-840). Linux already answers
EINVAL through the host fcntl. Check the minimum against the guest
RLIMIT_NOFILE before the Windows loop.
