This patch adds a couple of functions to allow section map updates to be temporarily inhibited. Without this ability, the calls to evaluate_probe_argument in svr4_handle_solib_event trigger a section map update every time a group of shared objects are mapped, which significantly affects performance. The updates are unnecessary in this case as the sections in question are in the runtime linker and so already in the section map.
