* cygwin.din: Export the new functions.

* pthread.cc (pthread_cond_*): Add wrapper functions that call __pthread_cond*
functions.
* thread.cc (__pthread_cond_*): Implement the pthread_cond* functions.
* thread.h: Add new class entries and prototypes for __pthread_cond* functions.
* include/pthread.h: user land header prototypes for pthread_cond* functions
and related defines.
