Share rand's generator step with rand_r, which advances the caller's
state instead of the global one, as FreeBSD's rand and rand_r share
do_rand.

Export sinh, cosh, coshf, asinh, asinhf, acosh, acoshf and atanh,
forwarding to the C++ standard library like tanh and tanhf.

Export it next to remainderf, stepping to the adjacent float in the
direction of the second argument.

Export it next to lroundf and llround, rounding halfway cases away
from zero into the 64-bit guest long long.

Export the double version next to __isnan and __isfinite, returning
1 for either infinity like __isinff.

RetroArch (PPSA99169) imports ldiv from libSceLibcInternal, one of the
absent imports #1578 lists for it. The guest long is 64-bit, so the
export takes std::int64_t and returns lldiv_t, which has the guest
ldiv_t layout; std::ldiv would truncate on Windows, where long is 32-bit.
hypotf now widens both arguments to double and calls the double hypot.
The float-to-double conversion raises FE_INVALID for a signaling NaN and
quiets it, so hypotf(sNaN, inf) returns +inf with the invalid flag set in
either argument order, matching the PS5 libc routine. Before, MinGW UCRT's
hypotf returned +inf without the flag and glibc's returned NaN.

Both forward to std::hypot, which computes without intermediate
overflow and returns infinity when either argument is infinite, even
if the other is NaN. The math test checks those cases.

Brings in main up to 9958d26 (homebrew runtime, POSIX wrappers in
libkernel, sce_module guest modules and --skip-sce-module, the --to-intel
general pipeline, libSceRandom, libSceRtc, libScePosixForWebKit,
libRenoirCore, test wiring).
Resolutions where both sides implemented the same thing:
- libkernel pthread: main's structure (lazy static initialisation,
destroyed markers, MutexOperations/CondOperations, mutex protocol and
condattr clock) with this branch's TimedWait deadlines and condition
(precise timed lock/wait on Windows), wait tracing, the adaptive mutex
type 4, POSIX default ERRORCHECK mutexes, EDEADLK/EPERM results instead
of throws, and condition clocks honoured for absolute timeouts.
- libc locale: the guest Dinkumware ABI (_Locimp, facet vtables, short
ctype/case tables, locale ids, stream storage) is kept because guest code
inlines those layouts; main's C character functions are kept on top.
- libc stdio/strings/math: main's stream functions (guest FILE status
sync), strerror/perror, remove, formatting, string and math exports win
over this branch's duplicates.
- libc paths: main's working directory with this branch's path aliases
resolved on the normalised guest path.
- libkernel file: this branch's sceKernel* results as SCE errors, main's
POSIX wrappers and both fstat helpers.
- relinker: this branch's stub lowering keeps its trampolines through the
main executable path; guest modules refuse lowerings that need stubs.
- AGC driver: main's rendering wait is executed by this branch's workers.

- libc: reserve guest memory in one arena below the PS5 map limit with
MEM_WRITE_WATCH (GuestArena) and a caching guest heap; the allocation
registry gains a generation counter, an invalidator callback for the
driver's page cache and a pin waiter for leased ranges. This replaces
the fault-based GuestMemoryTracking/GuestMemoryBacking layer, whose
files are removed.
- libkernel: mmap/mprotect/munmap on the arena, flexible memory budget,
real sceKernelVirtualQuery; POSIX pthread layer, rwlocks, timed locks,
TSD, event flags; 0.5 ms scheduler tick and high-resolution sleeps;
TSC/clock/time functions; file APIs return SCE errno codes; the APR
file-streaming API.
- libc: vectored crash reporter with backtraces for fatal exceptions,
SIGABRT, UCRT invalid parameters and process exit; SSE4a EXTRQ/INSERTQ
emulation for Intel hosts; %ls/%lc/%S/%C with the guest's 16-bit
wchar_t; hand-written setjmp/longjmp for the guest jmp_buf; a path
alias table for short save-data mount points; more string, stdio and
math exports.
