* breakpoint.c (insert_bp_location): If inserting the read
watchpoint failed, fallback to an access watchpoint.
(bpstat_check_watchpoint): Stop for read watchpoint triggers even
if the value changed, if not watching the same memory for writes.
(watchpoint_locations_match): Add comment.
(update_global_location_list): Copy the location's watchpoint type.

(i386_insert_watchpoint): Read watchpoints aren't supported.
* remote.c (remote_insert_watchpoint): Return 1 for unsupported
packets.
