	* proc-service.c (ps_pglobal_lookup): Use
	thread_db_look_up_one_symbol.
	* remote-utils.c (look_up_one_symbol): Add new `may_ask_gdb'
	parameter.  Use it instead of all_symbols_looked_up.
	* server.h (struct process_info) <all_symbols_looked_up>: Delete
	field.
	(all_symbols_looked_up): Don't declare.
	(look_up_one_symbol): Add new `may_ask_gdb' parameter.
	* thread-db.c (struct thread_db) <all_symbols_looked_up>: New
	field.
	(thread_db_look_up_symbols): Adjust call to look_up_one_symbol.
	Set all_symbols_looked_up here.
	(thread_db_look_up_one_symbol): New.
	(thread_db_get_tls_address): Adjust.
	(thread_db_load_search, try_thread_db_load_1): Always allocate the
	thread_db object on the heap, and tentatively set it in the
	process structure.
	(thread_db_init): Don't set all_symbols_looked_up here.
	* linux-low.h (thread_db_look_up_one_symbol): Declare.
