	* python/py-breakpoint.c (BPPY_REQUIRE_VALID): Check if bp is
	NULL.
	(BPPY_SET_REQUIRE_VALID): Ditto.
	(bpnum_is_valid): Delete function.
	(bppy_get_visibility): New function.
	(bppy_new): Parse for, and validate internal keyword.  Pass
	internal keyword to breakpoint or watchpoint functions.
	(build_bp_list): New function.
	(gdbpy_breakpoints): Rewrite.  Use build_bp_list and
	iterate_over_breakpoints.
	(gdbpy_breakpoint_created): Rewrite.  Do not store breakpoints in a
	look-aside vector.
	(gdbpy_breakpoint_deleted): Rewrite, defer breakpoint management
	to internal breakpoint chain.

	* breakpoint.c (set_breakpoint_number): New function.
	(breakpoint_1): Check if breakpoint number is more than zero.
	(set_raw_breakpoint_without_location): Set py_bp_object to NULL.
	(create_breakpoint_sal): Take a new parameter called internal.
	Call set_breakpoint_number with internal parameter.  Do not
	mention internal breakpoints.  All callers updated.
	(create_breakpoint): Ditto.
	(create_breakpoints_sal): Ditto.
	(watch_command_1): Ditto.
	(watch_command_wrapper): Take a new parameter called internal.
	All callers updated.

	(awatch_command_wrapper): Ditto.
	(save_breakpoints): Update breakpoint save condition check.
	(iterate_over_breakpoints): New function.
	* breakpoint.h: Add conditional python includes.  Add py_bp_object
	and comment to struct breakpoint.  Update all callers.
	* defs.h: Add PyObject definition for GDB builds without Python.
