c9bdadd541 sched/semaphore: Move cancel point and errno handling to libc / user-space
This moves all the public POSIX semaphore functions into libc and with
this most of the user-space logic is also moved; namely cancel point and
errno handling.

This also removes the need for the _SEM_XX macros used to differentiate
which API is used per user-/kernel mode. Such macros are henceforth
unnecessary.

0dedbcd4ae task/pthread_cancelpt: Move cancel point handling to libc, data to TLS
This moves task / thread cancel point logic from the NuttX kernel into
libc, while the data needed by the cancel point logic is moved to TLS.

The change is an enabler to move user-space APIs to libc as well, for
a coherent user/kernel separation.

2f9c082f8f fs_epoll: serveral epoll issues fix
1. fs_epoll: try again when epoll_teardown() return 0
when poll_notify() called larger than twice when epoll_wait() blocked
in the eph->sem, the semcount will be larger than 1 when epoll_wait()
unblocked and will return 0 directly at the next epoll_wait.
So retry to wait the eph->sem again when epoll_teardown return 0.

2. fs_epoll: poll_setup the fd again even this fd got non-expected event
Some poll implementations need call poll_setup again when their internal
states changed (e.g., local socket), so should add the fd to the epoll
teardown list and poll_setup again at the next epoll_wait even this fd
got the user non-expected event.

a2c5cb729a fs:support zipfs,can mount zipfile
we can mount a zipfile in nuttx use mount command like this:

mount -t zipfs -o /data/test.zip /zip

The zipfs is a read only file system,The advantage is that it
does not occupy additional space when reading the decompressed file.

When used, reading and decompression operations are simultaneous.
The known disadvantage is that when using seek to read forward,
it will reopen and cause slow speed problems.

8868c58720 Fix Deadloop in VFS if CONFIG_CANCELLATION_POINTS is enabled
If cancellation points are enabled, then the following logic is activated in sem_wait().  This causes ECANCELED to be returned every time that sem_wait is called.

    int sem_wait(FAR sem_t *sem)
    {
      ...

      /* sem_wait() is a cancellation point */

      if (enter_cancellation_point())
        {
    #ifdef CONFIG_CANCELLATION_POINTS
          /* If there is a pending cancellation, then do not perform
           * the wait.  Exit now with ECANCELED.
           */

          errcode = ECANCELED;
          goto errout_with_cancelpt;
    #endif
        }
      ...

Normally this works fine.  sem_wait() is the OS API called by the application and will cancel the thread just before it returns to the application.  Since it is cancellation point, it should never be called from within the OS.

There there is is one perverse cases where sem_wait() may be nested within another cancellation point.  If open() is called, it will attempt to lock a VFS data structure and will eventually call nxmutex_lock().  nxmutex_lock() waits on a semaphore:

   int nxmutex_lock(FAR mutex_t *mutex)
   {
     ...

     for (; ; )
       {
         /* Take the semaphore (perhaps waiting) */

         ret = _SEM_WAIT(&mutex->sem);
         if (ret >= 0)
           {
             mutex->holder = _SCHED_GETTID();
             break;
           }

         ret = _SEM_ERRVAL(ret);
         if (ret != -EINTR && ret != -ECANCELED)
           {
             break;
           }
       }
   ...
}

In the FLAT build, _SEM_WAIT expands to sem_wait().  That causes the error in the logic:  It should always expand to nxsem_wait().  That is because sem_wait() is cancellation point and should never be called from with the OS or the C library internally.

The failure occurs because the cancellation point logic in sem_wait() returns -ECANCELED (via _SEM_ERRVAL) because sem_wait() is nested; it needs to return the -ECANCELED error to the outermost cancellation point which is open() in this case.  Returning -ECANCELED then causes an infinite loop to occur in nxmutex_lock().

The correct behavior in this case is to call nxsem_wait() instead of sem_wait().  nxsem_wait() is identical to sem_wait() except that it is not a cancelation point.  It will return -ECANCELED if the thread is canceled, but only once.  So no infinite loop results.

In addition, an nxsem_wait() system call was added to support the call from nxmutex_lock().

This resolves Issue #9695

8fe8417ffb libc/fdcheck: add fdcheck module
In embedded development environments, due to the lack of address isolation between processes,
fd may be passed between processes and lead to misuse,

We have designed an fd cross-process automatic detection tool,
fdcheck_protect returns the fd containing the pid information,
indicating that the ownership of the current fd belongs to the pid and is not allowed to be used by other processes.
fdcheck_restore will obtain the true fd and check if the ownership of the fd is legal

For ease of understanding, let's give an example where
the following information is represented in 32-bit binary format

fd        00000000 00000000 00000000 10001010
pid       00000000 00000000 00000011 01010101

360e938fa6 sched: add support for adjtime() interface
This commit adds Linux like adjtime() interface that is used to correct
the system time clock if it varies from real value. The adjustment is
done by slight adjustment of clock period and therefore the adjustment
is without time jumps (both forward and backwards)

The implementation is enabled by CONFIG_CLOCK_ADJTIME and separated from
CONFIG_CLOCK_TIMEKEEPING functions. Options CONFIG_CLOCK_ADJTIME_SLEWLIMIT
and CONFIG_CLOCK_ADJTIME_PERIOD can be used to control the adjustment
speed.

Interfaces up_get_timer_period() and up_adj_timer_period() has to be
defined by architecture level support.

This is not a POSIX interface but derives from 4.3BSD, System V.
It is also supported for Linux compatibility.
