John Baldwin dc3566067a Ensure thread library is initialized in pthread_testcancel(). 
Call _thr_check_init() before reading curthread in pthread_testcancel().

If a constructor in a library creates a semaphore via sem_init() and
then waits for it via sem_wait(), the program can core dump in
_pthread_testcancel() called from sem_wait().  This is because the
semaphore implementation lives in libc, so the library's constructors
can be run before libthr's constructors.
