Support 'info proc' for FreeBSD process core dumps.
- Command line arguments are obtained from the pr_psargs[] array saved in the NT_PRPSINFO note. - The 'cwd' and 'exe' values are obtained from the per-process file descriptor table stored in the NT_PROCSTAT_FILES core note. - 'mappings' is implemented by walking the array of VM map entries stored in the NT_PROCSTAT_VMMAP core note. - 'status' output is generated by outputting fields from the first structure stored in the NT_PROCSTAT_PROC core note. - 'stat' is aliased to 'status'. gdb/ChangeLog: * fbsd-tdep.c (KVE_STRUCTSIZE, KVE_START, KVE_END, KVE_OFFSET) (KVE_FLAGS, KVE_PROTECTION, KVE_PATH, 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_SUPER, KINFO_VME_FLAG_GROWS_UP) (KINFO_VME_FLAG_GROWS_DOWN, KF_STRUCTSIZE, KF_TYPE, KF_FD) (KF_PATH, KINFO_FILE_TYPE_VNODE, KINFO_FILE_FD_TYPE_CWD) (KINFO_FILE_FD_TYPE_TEXT, SIG_WORDS, struct kinfo_proc_layout) (kinfo_proc_layout_32, kinfo_proc_layout_i386) (kinfo_proc_layout_64, fbsd_vm_map_entry_flags) (fbsd_core_info_proc_mappings, fbsd_core_vnode_path) (fbsd_core_fetch_timeval, fbsd_print_sigset) (fbsd_core_info_proc_status, fbsd_core_info_proc): New.
