This patch consolidate the remaning non cancellable syscall definitions on not-cancel.h header. They are: * __fcntl_nocancel: Moved from fcntl.h to not-cancel.h. * __sigsuspend_nocancel: Removed since988f991b50it is not used or defined anymore. * __nanosleep_nocancel: Removed since6f33fd046bit is defined on not-cancel.h. Now all non-cancellable syscall definition are defined on not-cancel (the only exceptions is the stdio symbol __fxprintf_nocancel which uses non cancellable open and it is used on getopt implementation). Checked on x86_64-linux-gnu and with build-many-glibc.py. * include/fcntl.h (__fcntl_nocancel): Remove definition. * include/signal.h (__sigsuspend_nocancel): Likewise. * include/time.h (__nanosleep_nocancel): Likewise. * sysdeps/generic/not-cancel.h (__fcntl_nocancel): New macro. * login/utmp_file.c: Include non cancellable syscall header. * sysdeps/unix/sysv/linux/not-cancel.h (__fcntl_nocancel): New prototype.
