and add _nocancel variant.
* sysdeps/mach/hurd/Makefile [io] (sysdep_routines): Add fcntl_nocancel.
* sysdeps/mach/hurd/fcntl.c [NOCANCEL]: Include <not-cancel.h>.
[!NOCANCEL]: Include <sysdep-cancel.h>.
(__libc_fcntl) [!NOCANCEL]: Surround __file_record_lock call with enabling async cancel, and use HURD_FD_PORT_USE_CANCEL instead of HURD_FD_PORT_USE.
* sysdeps/mach/hurd/fcntl_nocancel.c: New file, defines __fcntl_nocancel by including fcntl.c.
* sysdeps/mach/hurd/not-cancel.h (__fcntl64_nocancel): Replace macro with
__fcntl_nocancel declaration with hidden proto, and make
__fcntl64_nocancel call __fcntl_nocancel.
