Consolidate non cancellable pause call
This patch consolidates all the non cancellable pause calls to use the __pause_nocancel identifier. For non cancellable targets it will be just a macro to call the default respective symbol while on Linux will be a internal one. Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu. * nptl/pthread_mutex_lock.c (__pthread_mutex_lock_full): Replace pause_not_cancel with __pause_nocancel. * sysdeps/generic/not-cancel.h (pause_not_cancel): Remove macro. (__pause_nocancel): New macro. * sysdeps/unix/sysv/linux/not-cancel.h (pause_not_cancel): Remove macro. (__pause_nocancel): New prototype. * sysdeps/unix/sysv/linux/pause.c (__pause_nocancel): New function.
