1. the lio_sigsetup() method use a universal sighand instance across all
aiocb instances, but inside the lio_sighandler() method, if one aiocb is
handle finished, then this method will free the sighand instance that
come along with current aiocb instance. thus when handle next aiocb
instance, use-after-free crash will happen. in order to solve this
problem, we make each aiocb instance have their own sighand instance
2. make the lio_listio implementation can pass the
ltp/open_posix_testsuite/lio_listio testcases
3. the modification are referred to https://pubs.opengroup.org/onlinepubs/9699919799/functions/lio_listio.html

NuttX kernel should not use the syscall functions, especially after
enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions
will be traced to backend, which will impact system performance.

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
Squashed commit of the following:
mm/iob: The IOB available notifier is now just a wrapper around the common signal notifier.
sched/signal: Add a generic signal notification facility.
sched/signal/sig_evthread.c: More trivial naming changes.
sched/signal: Rename nxsig_notification() to nxsig_evthread() to make forthcoming naming additions more consistent.
Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.
