Kamil Rytarowski 54b8cbd0e4 Implement "info proc mappings" for NetBSD
Define nbsd_nat_target::find_memory_regions and
nbsd_nat_target::info_proc. info_proc handles as of now only
the "mappings" command.

Define a local static function kinfo_get_vmmap() that reads
the process memory layout of a specified process.
kinfo_get_vmmap() wraps the sysctl(3) call.

nbsd-tdep.c defines now utility functions for printing the
process memory layout:
 * nbsd_info_proc_mappings_header()
 * nbsd_vm_map_entry_flags()
 * nbsd_info_proc_mappings_entry()

gdb/ChangeLog:

	* nbsd-nat.c; Include "nbsd-tdep.h" and "gdbarch.h".
	* nbsd-nat.c (nbsd_nat_target::find_memory_regions)
	(nbsd_nat_target::info_proc): New functions.
	* nbsd-nat.c (kinfo_get_vmmap): New function.
	* nbsd-nat.c (nbsd_nat_target::info_proc) Use
	nbsd_info_proc_mappings_header and nbsd_info_proc_mappings_entry.
	* nbsd-tdep.c (nbsd_info_proc_mappings_header)
	(nbsd_info_proc_mappings_entry, nbsd_vm_map_entry_flags): New
	functions.
	* nbsd-tdep.c (KINFO_VME_PROT_READ, KINFO_VME_PROT_WRITE)
	(KINFO_VME_PROT_EXEC, KINFO_VME_FLAG_COW)
	(KINFO_VME_FLAG_NEEDS_COPY, KINFO_VME_FLAG_NOCOREDUMP)
	(KINFO_VME_FLAG_PAGEABLE, KINFO_VME_FLAG_GROWS_UP)
	(KINFO_VME_FLAG_GROWS_DOWN): New.
