Use __pthread_setcancelstate in libc.a
This patch references __pthread_setcancelstate instead of pthread_setcancelstate in libc.a. [BZ #18970] * misc/error.c (error): Replace pthread_setcancelstate with __pthread_setcancelstate. (error_at_line): Likewise. * posix/wordexp.c (parse_comm): Likewise. * stdlib/fmtmsg.c (fmtmsg): Likewise. * nptl/forward.c (pthread_setcancelstate): Renamed to ... (__pthread_setcancelstate): This. (pthread_setcancelstate): Add an alias. * nptl/nptl-init.c (pthread_functions): Replace ptr_pthread_setcancelstate with ptr___pthread_setcancelstate. * sysdeps/nptl/pthread-functions.h (pthread_functions): Likewise. * nptl/pthreadP.h (__pthread_setcancelstate): Mark it with hidden_proto. * nptl/pthread_setcancelstate.c (__pthread_setcancelstate): Mark it with hidden_def. * sysdeps/nptl/libc-lockP.h (__pthread_setcancelstate): New. (pthread_setcancelstate): Renamed to ... (__pthread_setcancelstate): This. * sysdeps/unix/sysv/linux/fatal-prepare.h (FATAL_PREPARE): Use __libc_ptf_call with __pthread_setcancelstate.
