76793d4d51 Fix aio system call wrappers in librt. 
- Update aio_return/waitcomplete wrappers for the ssize_t return type.
- Fix the aio_return() wrapper to fail with EINVAL on a pending job.
  This matches the semantics of the in-kernel system call.  Also,
  aio_return() returns errors via errno, not via the return value.

c5a4f4eff2 1. Always call user callback function in newly created thread, it seems 
POSIX implies that the user callback function must be executed in clean
environment.
2. Use newly introduced pthread stubs in libc.

6348ace8d1 Use a thread pool to process notification if sigev_notify_attributes 
is default and caller does not require dedicated thread. timer needs
a dedicated thread to maintain overrun count correctly in notification
context. mqueue and aio can use thread pool to do notification
concurrently, the thread pool has lifecycle control, some threads will
exit if they have idled for a while.

Current the library implements mqueue, timer and aio with SIGEV_THREAD
notification supported.
