d7f02a8cb6 sched: change pthread_mutex implementation from sem to mutex 
Since pthread_mutex is implemented by sem, it is impossible to see in ps who holds the lock and causes the wait.
Replace sem with mutex implementation to solve the above problems

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.

11cc232de5 pthread_mutex_timedlock never returns EINTR 
According to posix spec, this function should never return `EINTR`.

This fixes the call to `pthread_mutex_take` so it keeps retrying the
lock and doesn't return `EINTR`

0951151c33 libs/libc/pthread, syscall/, and include/sys/syscall.h: Support for pthread_mutex_timedlock() was added recently, however no new system call was added for the API make is usable only in the FLAT build. With a pthread_mutex_timedlock() system call, there is no reason for a pthread_mutex_lock() system call since it is now nothing more than an wrapper around pthread_mutex_timedlock(), passing NULL for the time value. The pthread_mutex_lock() syscall was removed and the pthread_mutex_lock() implemented was moved from /sched/pthread to where it now belows in libs/libc/pthread. 2019-02-25 18:19:13 -06:00
