* maint.c: New file.

	* Makefile.in (SFILES_MAINDIR):  Add new file maint.c.
	* Makefile.in (OBS):  Add new file maint.o.
	* defs.h (command_class):  Add class_maintenance.
	* defs.h (MAINTENANCE_CMDS):  Default to including maintenance
	commands.  Allow for them (and other nonessential parts of gdb)
	to be selectively left out under special circumstances.
	* gdbtypes.c (recursive_dump_type):  New function; supports
	maintenance print-type command.
	* gdbtypes.h (recursive_dump_type, maintenance_print_type):
	Add prototypes.
	* main.c (maintenancelist, maintenanceinfolist):  Add maintenance
	command lists.
	* main.c (initialize_cmd_lists):  Eliminate unnecessary casts on
	initializers.  Add initializations for setprintlist, showprintlist,
	setchecklist, showchecklist, maintenancelist, and maintenanceinfolist.
	* printcmd.c (maintenance_print_type):  New maintenance cmd.
	* valprint.c (setprintlist, showprintlist):  Move to main.c, as
	implied by comment that all cmd lists are owned by main.c.
	* infcmd.c (unsetlist):  Move to main.c, as implied by comment
	that all cmd lists are owned by main.c.
	* language.c (setchecklist, showchecklist):  Move to main.c, as
	implied by comment that all cmd lists are owned by main.c
	* breakpoint.c (enablelist, enablebreaklist, disablelist, cmdlist,
	deletelist):  Remove redundant declarations (also in gdbcmd.h).
	* symmisc.c (printsyms_command):  Now maintenance_print_symbols.
	* symmisc.c (printmsyms_command):  Now maintenance_print_msymbols.
	* symmisc.c (printpsyms_command):  Now maintenance_print_psymbols.
	* symmisc.c (printobjfiles_command):  Now maintenance_print_objfiles.
	* symtab.h (maintenance_print_symbols, maintenance_print_psymbols,
	maintenance_print_msymbols, maintenance_print_objfiles):
	Add prototypes.
	* symmisc.c (printsyms_command, printpsyms_command,
	printmsyms_command, printobjfiles_command):  Removed from
	_initialize_symmisc.
	* main.c (dump_me_command):  Moved to maint.c and renamed to
	maintenance_dump_me.
	* breakpoint.c (all_breakpoints_info):  Rename to
	maintenance_info_breakpoints.
	* breakpoint.c (_initialize_breakpoint):  Convert add_info of
	all_breakpoints_info to add maintenance_info_breakpoints to the
	maintenanceinfolist instead.
	main.c (initialize_main):  Set up maintenance class commands.
