* breakpoint.h (enum enable_state): Add bp_startup_disabled.

	(disable_breakpoints_before_startup): Add prototype.
	(enable_breakpoints_after_startup): Likewise.

	* breakpoint.c (executing_startup): New static variable.
	(describe_other_breakpoints): Handle bp_startup_disabled.
	(check_duplicates_for): Likewise.
	(disable_breakpoints_before_startup): New function.
	(enable_breakpoints_after_startup): New function.
	(create_breakpoint): Mark new breakpoints as bp_startup_disabled
	if executing_startup flag is true.
	(break_command_really): Likewise.
	(breakpoint_re_set_one): Skip bp_startup_disabled breakpoints.
