Add the ability to recognize old references to keys, and return NULL

2002-03-19T22:58:56+00:00

when old keys are referenced (after pthread_key_delete()) via
pthread_getspecific().

To be consistent, use the __weak_reference macro from

2001-04-10T04:19:21+00:00

instead of #pragma weak to create weak definitions.

Suggested by:	bde

Add weak definitions for wrapped system calls. In general:

2001-01-24T13:03:38+00:00

	_foo - wrapped system call
	foo - weak definition to _foo

and for cancellation points:

	_foo - wrapped system call
	__foo - enter cancellation point, call _foo(), leave
	        cancellation point
	foo - weak definition to __foo

Change use of global _thread_run to call a function to get the
currently running thread.

Make all pthread_foo functions weak definitions to _pthread_foo,
where _pthread_foo is the implementation.  This allows an application
to provide its own pthread functions.

Provide slightly different versions of pthread_mutex_lock and
pthread_mutex_init so that we can tell the difference between
a libc mutex and an application mutex.  Threads holding mutexes
internal to libc should never be allowed to exit, call signal
handlers, or cancel.

- Fixed bug where we NULL'd before we freed the data causing a memory leak.
