4c8d244fae sched/getpid: replace syscall getpid/tid/ppid() to kernel version
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.

8021dfece6 sched/task/task_getpid: getpid should return process id not thread id
Summary:
   implement the right semantics:
1. getpid should return the main thread id
2. gettid should return the current thread id

1416afc6b6 sched: Remove "0x" prefix preceding "%p" specifier on format string
The "p" format specifier already prepends the pointer address with
"0x" when printing.

89338a6914 sched/pthread/pthread_condclockwait.c: follow POSIX.
pthread_condclockwait() can not distinguish between interrupt and timeout,
which cause these API not follow POSIX:
	pthread_rwlock_timedrdlock()
	pthread_rwlock_timedwrlock()
	pthread_condtimedwait()
POSIX:
	Upon return from the signal handler the thread resumes waiting for
	the condition variable as if it wasnot interrupted
	These functions shall not return an error code of [EINTR].

Replacing nxsem_wait() with nxsem_clockwait_uninterruptible() can solve it.

102a6357ca Revert "sched: Remove a redundant critical section"
There is a potential problem that can lead to deadlock at
condition wait, if the timeout of watchdog is a very small value
(1 tick ?), the timer interrupt will come before the nxsem_wait()
