	* server.c (handle_query): Advertise support for target-side
	breakpoint condition evaluation.
	(process_point_options): New function.
	(process_serial_event): When inserting a breakpoint, check for
	a target-side condition that should be evaluated.

	* mem-break.c: Include regcache.h and ax.h.
	(point_cond_list_t): New data structure.
	(breakpoint) <cond_list>: New field.
	(find_gdb_breakpoint_at): Make non-static.
	(delete_gdb_breakpoint_at): Clear any target-side
	conditions.
	(clear_gdb_breakpoint_conditions): New function.
	(add_condition_to_breakpoint): Likewise.
	(add_breakpoint_condition): Likewise.
	(gdb_condition_true_at_breakpoint): Likewise.
	(gdb_breakpoint_here): Return result directly instead
	of going through a local variable.

	* mem-break.h (find_gdb_breakpoint_at): New prototype.
	(clear_gdb_breakpoint_conditions): Likewise.
	(add_breakpoint_condition): Likewise.
	(gdb_condition_true_at_breakpoint): Likewise.

	* linux-low.c (linux_wait_1): Evaluate target-side breakpoint condition.
	(need_step_over_p): Take target-side breakpoint condition into
	consideration.
