Modified files:
	rda/unix       : ChangeLog configure configure.in 
	                 gdbserv-thread-db.h ptrace-target.c server.h 
	                 thread-db.c 
Added files:
	rda/unix       : lwp-ctrl.h lwp-pool.c lwp-pool.h 

Log message:
	Separate management of kernel-level LWPs from that of libpthread /
	libthread_db-level threads.
	* lwp-pool.c, lwp-pool.h: New files.
	* thread-db.c: #include "lwp-ctrl.h" and "lwp-pool.h".
	(struct gdbserv_thread): Delete members 'attached', 'stopped',
	'waited', and 'stepping'.  This structure is now just a
	'td_thrinfo_t' and a list link.  Describe some quirks in the
	meanings of certain 'ti' fields.
	(thread_list_lookup_by_lid): Move later in file, so we can use
	information directly from our proc handle.  Be skeptical of ZOMBIE
	or UNKNOWN threads whose LWP ID is equal to the PID in the proc
	handle.
	(thread_debug_name): Move later in file, so we can use
	thread_db_state_str.
	(attach_thread): Use lwp pool functions to attach.  Attach to
	zombies.  When using signal-based communication, send the thread
	the restart signal immediately.
	(find_new_threads_callback): Go ahead and attach to all threads.
	The LWP pool functions tolerate attaching to a given LWP more than
	once.
	(update_thread_list): Take the process as an argument.  If the
	focus thread has disappeared, set process->focus_thread to NULL.
	(thread_db_thread_next): Pass the process to update_thread_list.
	(stop_thread, stop_all_threads, add_pending_event,
	delete_pending_event, select_pending_event, send_pending_signals,
	wait_all_threads, continue_all_threads): Deleted.
	(handle_thread_db_event): Renamed from handle_thread_db_events.
	Take the process structure as an argument, and check only for a
	thread-db event notification from process->event_thread.  Use LWP
	pool functions.
	(continue_thread, singlestep_thread): Use LWP pool functions.
	(thread_db_continue_program, thread_db_singlestep_program,
	thread_db_continue_thread, thread_db_singlestep_thread): Use LWP
	pool functions, and update process->focus_thread appropriately.
	(thread_db_check_child_state): Use the LWP pool functions.  Rather
	than stopping all LWP's, choosing the most interesting events, and
	then arranging to re-create all the other wait statuses we got,
	just pick the first event we get from lwp_pool_waitpid (either on
	the focus thread, if there is one, or on any thread) and report
	that.  Use the new handle_thread_db_event function.
	(struct event_list, pending_events, pending_events_listsize,
	pending_events_top): Deleted; replaced by LWP pool code.
	(thread_db_attach): Tell the LWP pool about the PID we're
	attaching to.  Clear the focus thread.
	* server.h (struct process): New member: 'focus_thread'.
	* gdbserv-thread-db.h (continue_lwp, singlestep_lwp, attach_lwp,
	stop_lwp): Move declarations from here...
	* lwp-ctrl.h: ... to here.  New file.
	(kill_lwp): Renamed from stop_lwp; allow caller to specify any
	signal.
	* ptrace-target.c: #include "lwp-ctrl.h".
	(continue_lwp, singlestep_lwp, attach_lwp, stop_lwp): Move
	function comments to lwp-ctrl.h, and expand.
	* configure.in: Whenever we select 'thread-db.o', select
	'lwp-pool.o' as well.
	* configure: Regenerated.
	
	* thread-db.c (thread_db_check_child_state): Remove extraneous
	call to handle_waitstatus.  Remove extra check for exited main
	thread.
	
	* thread-db.c (thread_db_thread_info): List the type and state
	before the PID, and mention whether the LWP's PID is equal to that
	of the main thread, since ZOMBIE and UNKNOWN threads whose LWP's
	PID is equal are probably actually exited threads.
	
	* thread-db.c (add_thread_to_list): Zero out entire structure.
	
	* thread-db.c (thread_db_state_str, thread_db_type_str): Remove
	spaces from names; we don't always want them, and the caller can
	use printf formatting directives to arrange things as they please.
	
	* ptrace-target.c (continue_lwp, singlestep_lwp, attach_lwp,
	stop_lwp): Change arguments from 'lwpid_t' to 'pid_t'.  lwpid_t is
	strictly a thread-db type; these are functions that use system
	calls, which all expect pid_t.  Rename arguments from 'lwpid' to
	'pid'.
	
	* ptrace-target.c: #define _GNU_SOURCE to get declaration for
	strsignal.
	(kill_lwp): Enhance error reporting.
