* Makefile.in (armnbsd-nat.o): Update dependencies.

* armnbsd-nat.c (supply_gregset): New function.  Common code to
supply the integer register set.
(supply_fparegset): New function.  Similar for FPA registers.
(fetch_regs, fetch_fp_regs): Use them.
(fetch_core_registers): Likewise.
(fetch_elfcore_registers): New function.
(arm_netbsd_elfcore_fns): New core-file type specification.
(_initialize_arm_netbsd_nat): Register it.
