	gdb            : ChangeLog objfiles.c solib.c target.c target.h 

Log message:
	Deal with the inferior unloading shared objects.
	* solib.c (current_sos): New function, replacing find_solib.
	(find_solib): Deleted.
	(free_so): New function.
	(clear_solib): Call free_so, instead of writing it out.
	(solib_add): Rewritten: compare the inferior's current list of
	shared objects with GDB's list, and do the required loads and
	unloads.
	(info_sharedlibrary_command, solib_address): Don't use find_solib
	to walk the list of shared libraries: call solib_add, and then
	walk the list at so_list_head normally.
	* objfiles.c (free_objfile): Don't call CLEAR_SOLIB, and don't
	detach the core target.  These tasks are taken care of elsewhere.
	* target.c (remove_target_sections): New function.
	* target.h (remove_target_sections): New declaration.
	
	* solib.c (symbol_add_stub): Check whether we've already created
	an objfile for this shared object first, before doing all that
	work to compute section addresses, etc.
	
	* objfiles.c (unlink_objfile): Report an internal error if objfile
	doesn't occur in the object_files list.
	
	* solib.c (special_symbol_handling): Delete argument; it's not
	used.
	
	* solib.c (SOLIB_EXTRACT_ADDRESS):  New macro to extract addresses
	from solib structures. Use it throughout solib.c, get rid of all
	CORE_ADDR casts.
	(struct so_list):  Change type of lmaddr to CORE_ADDR.
	(first_link_map_member):  Change return value type to CORE_ADDR,
	update callers.
	(solib_add_common_symbols):  Change parameter type to CORE_ADDR,
	update callers.
	(open_symbol_file_object, find_solib):  Change type of lm variable
	to CORE_ADDR.
