hurd: implement RLIMIT_AS against Mach RPCs
Check for VM limit RPCs
* config.h.in: add #undef for HAVE_MACH_VM_GET_SIZE_LIMIT and
HAVE_MACH_VM_SET_SIZE_LIMIT.
* sysdeps/mach/configure.ac: use mach_RPC_CHECK to check for
vm_set_size_limit and vm_get_size_limit RPCs in gnumach.defs.
* sysdeps/mach/configure: regenerate file.
Use vm_get_size_limit to initialize RLIMIT_AS
* hurd/hurdrlimit.c(init_rlimit): use vm_get_size_limit to initialize
RLIMIT_AS entry of the _hurd_rlimits array.
Notify the kernel of the new VM size limits
* sysdeps/mach/hurd/setrlimit.c: use the vm_set_size_limit RPC,
if available, to notify the kernel of the new limits. Retry RPC
calls if they were interrupted by a signal.
