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.
