74604ed9c4 To support stack unwinding for cancellation points, add -fexceptions flag 
for them, two functions _pthread_cancel_enter and _pthread_cancel_leave
are added to let thread enter and leave a cancellation point, it also
makes it possible that other functions can be cancellation points in
libraries without having to be rewritten in libthr.

09818ac28e Build lib/ with WARNS=6 by default. 
Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

bf3a79274d Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it. 
Warning, after symbol versioning is enabled, going back is not easy
(use WITHOUT_SYMVER at your own risk).

Change the default thread library to libthr.

There most likely still needs to be a version bump for at least the
thread libraries.  If necessary, this will happen later.

instead of pthread_create.

13fd270405 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.

8e36ba772a 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.

22fb15cfe9 Bring in my initial version of POSIX realtime extension library. 
Current the library implements mqueue, timer and aio with SIGEV_THREAD
notification supported.
