Provide backwards binary compatibility for the Hurd. * hurd/geteuids.c [PIC && DO_VERSIONING]: Make __getuids a weak alias for geteuids. * hurd/Versions [GLIBC_2.0]: Add __getuids, __hurd_file_name_lookup and _hurd_umask. [GLIBC_2.1]: Add _hurd_proc_init. * hurd/Makefile [versioning] (routines): Add compat-20. (shared-only-routines): Likewise. * hurd/hurdinit.c (_hurd_new_proc_init): Renamed from _hurd_proc_init. Use it as the default _hurd_proc_init version for GLIBC_2.1. * hurd/compat-20.c: New file. * mach/Versions [GLIBC_2.0]: Add __vm_allocate.
