hurd: make close a cancellation point
and add _nocancel variant. * sysdeps/mach/hurd/Makefile [io] (sysdep_routines): Add close_nocancel. * sysdeps/mach/hurd/Versions (libc.GLIBC_PRIVATE, ld.GLIBC_PRIVATE): Add __close_nocancel. * sysdeps/mach/hurd/i386/localplt.data (__close_nocancel): Allow PLT. * sysdeps/mach/hurd/close.c: Include <sysdep-cancel.h> (__libc_close): Surround _hurd_fd_close with enabling async cancel. * sysdeps/mach/hurd/close_nocancel.c: New file. * sysdeps/mach/hurd/not-cancel.h (__close_nocancel): Replace macro with declaration with hidden proto.
