	                 stock-breakpoints.c stock-breakpoints.h 

Log message:
	Add support for the Linux NPTL (New POSIX Thread Library) thread
	implementation.
	* arch.h, lwp-pool.c, lwp-pool.h, stock-breakpoints.c:
	* stock-breakpoints.h: New files.
	* gdbserv-thread-db.h (continue_lwp, singlestep_lwp, attach_lwp)
	(stop_lwp): Move these ...
	* lwp-ctrl.h: ... to here (new file).
	* server.h (struct child_process): Include a pointer to the
	architecture object, a breakpoint table, and a pointer to the
	"focus thread".
	* linux-target.c: Create architecture objects for the i386 and
	FRV, and describe breakpoints for those architectures.
	#include "arch.h".
	[STOCK_BREAKPOINTS]: #include "stock-breakpoints.h".
	(allocate_empty_arch): New function.
	[X86_LINUX_TARGET] (stock_table_to_x86, x86_table_to_stock)
	(stock_bp_to_x86, x86_bp_to_stock, x86_make_bp_table, x86_set_bp)
	(x86_delete_bp, x86_bp_hit_p, x86_make_arch): New functions.
	(MAKE_ARCH): #define to call x86_make_arch.
	[X86_LINUX_TARGET] (stock_table_to_frv, frv_table_to_stock)
	(stock_bp_to_frv, frv_bp_to_stock, frv_make_bp_table, frv_set_bp)
	(frv_delete_bp, frv_bp_hit_p, frv_make_arch): New functions.
	(MAKE_ARCH): #define to call frv_make_arch.
	(linux_attach): If MAKE_ARCH is #defined, create an architecture
	object for this process.  And if we have an architecture object,
	make a breakpoint table.
	* thread-db.c: #include <assert.h>, "arch.h", "lwp-ctrl.h", and
	"lwp-pool.h".
	(struct gdbserv_thread): Remove state-tracking flags 'attached',
	'stopped', 'waited', and 'stepping'; all that state is handled
	inside lwp-pool.c now.
	(add_thread_to_list): Zero the entire newly allocated thread
	structure.
	(thread_list_lookup_by_lid): Prefer threads whose ti_lid values
	are different from that of the main process.
	(thread_db_state_str, thread_db_type_str): Don't include
	formatting spaces here.
	(thread_db_event_str): New function.
	(thread_debug_name): New function.
	(get_thread_signals): Return a value indicating success or failure.
	(ignore_thread_signal): New function.

	variables and functions, for using libthread_db's event interface.
	(thread_db_open): Gather error-handling code next to the operation
	that might fail.  Decide here whether to use the signal-based
	debugging interface, or the event-based debugging interface.
	(stop_thread, stop_all_threads, struct event_list, pending_events)
	(pending_events_listsize, pending_events_top, add_pending_event)
	(select_pending_event, send_pending_signals, wait_all_threads):
	Deleted; we now use lwp-pool.c for all this.
	(attach_thread, continue_thread, continue_all_threads)
	(singlestep_thread, thread_db_singlestep_program)
	(thread_db_continue_thread, thread_db_singlestep_thread): Use the
	lwp-pool.c functions, instead of calling the lwp manipulation
	functions directly and managing state here.  Keep track of the
	focus thread.
	(find_new_threads_callback): Always call attach_thread.  If we're
	using libthread_db events, enable event reporting for the new
	thread.
	(update_thread_list): Take the current child process as an
	argument; if the current focus thread disappears, clear the
	process's focus_thread pointer.
	(thread_db_thread_next): Pass the current child process to
	update_thread_list.
	(thread_db_thread_info): Reformat thread descriptions.  Mark
	threads whose pid is equal to the process ID.
	(thread_db_check_child_state): Use the lwp-pool functions, instead
	of calling waitpid and the old stop-all-threads functions.  If we
	have a focus thread, only check for a status on that thread.
	Check for libthread_db events.  Use ignore_thread_signal, instead
	of writing it out.
	(thread_db_break_program): New function.
	(thread_db_attach): Register it as the target's 'break_program'
	method.  Always preload the symbol list with the names we'll need
	for the signal-based interface, even if we have td_symbol_list.
	Use lwp_pool_new_stopped to register the initial thread.  Clear
	the focus thread.
	* ptrace-target.c: #define _GNU_SOURCE and #include <sys/types.h>
	and <linux/unistd.h>, to get declarations for the functions we
	need.
	#include "lwp-ctrl.h".
	(continue_lwp, singlestep_lwp, attach_lwp): Remove
	unnecessary 'extern' keywords.  Move pre-function comments to
	lwp-ctrl.h.  Take an ordinary 'pid_t', not an 'lwpid_t', since
	we're calling ptrace / tkill, and that's what they expect; rename
	arguments accordingly.  Preserve value of errno across calls to
	fprintf when reporting errors.
	(kill_lwp): All the above, and use tkill system call if available.
	* configure.in: Whenever we include thread-db.o in TARGET_MODULES,
	also include lwp-pool.o.
	On i386 and FRV Linux, use the stock-breakpoints module.
	* config.in: Add template for STOCK_BREAKPOINTS.
	* Makefile.am (EXTRA_rda_SOURCES): Include stock-breakpoints.c.
	* Makefile.in, aclocal.m4, configure: Regenerated.

	(allocate_empty_arch): New function.
	(x86_make_arch): New function.
	(MAKE_ARCH): New #definition.
	(linux_attach): Initialize process's architecture.
	
	Provide arch-independent framework for breakpoints.
	* server.h (struct arch_bp_table): New forward struct declaration.
	(struct child_process): New member: 'breakpoint_table'.
	* linux-target.c (linux_attach): Initialize process's breakpoint
	table, if the architecture defines a breakpoint table constructor.
	* arch.h (struct arch): Add fields pointing to breakpoint functions.
	
	Provide a module implementing breakpoints for architectures that
	support a simple software breakpoint model ("patch these bytes
	into the instruction stream").
	* stock-breakpoints.h, stock-breakpoints.c: New files.
	* linux-target.c: If STOCK_BREAKPOINTS is #defined, then #include
	"stock-breakpoints.h".
	* Makefile.am (EXTRA_rda_SOURCES): Add stock-breakpoints.c.
	* Makefile.in: Updated.
	
	Define x86 breakpoint functions using the stock-breakpoints.c
	model.
	* configure.in: When configuring for an x86 target, include
	stock-breakpoints.o in the mix, and #define STOCK_BREAKPOINTS.
	* configure: Regenerated.
	* config.in (STOCK_BREAKPOINTS): Provide #definition template.
	* linux-target.c (stock_table_to_x86, x86_table_to_stock,
	stock_bp_to_x86, x86_bp_to_stock, x86_make_bp_table, x86_set_bp,

	supported.
	* thread-db.c: #include <assert.h>.
	(thread_db_event_str): New function.
	(get_target_int_by_name, set_target_int_by_name, get_thread_signals)
	(cancel_signal, restart_signal, debug_signal): Move these to just
	before thread_db_dlopen; get_thread_signals is a subroutine of that.
	(using_thread_db_events, create_notification, death_notification,
	create_event_breakpoint, death_event_breakpoint): New global vars.
	(get_event_notification, set_event_breakpoint)

	the signal-based interface.
	(thread_db_check_child_state): If we're using the libthread_db
	event interface to communicate with the inferior thread library,
	check for those events here.  If select_pending_event says it
	didn't find anything interesting, that means we consumed all the
	reportable events; continue the program silently.
	* ptrace-target.c: #include <sys/types.h> and <linux/unistd.h>.
	(tkill): Generate code for this syscall.
	(stop_lwp): Use tkill instead of kill.
	
	* thread-db.c (thread_db_check_child_state): Call stop_all_threads
	before calling update_thread_list, so RDA will have to compete for
	CPU with fewer running threads.
	
	* thread-db.c (wait_all_threads): Move calls to
	select_pending_event and send_pending_signals from here...
	(thread_db_check_child_state): To here.

	(thread_db_check_child_state): Call it, instead of writing it out.
	
	* thread-db.c (thread_db_open): Return 0 on success, -1 on
	failure, like most of the other int-valued functions in this file,
	and like most system calls.

	* thread-db.c: #include "gdbserv-utils.h", to get prototypes for
	the 'struct gdbserv_reg' manipulation functions.
	
	* thread-db.c (thread_db_noisy): Initialize to 1.
	
	* thread-db.c (thread_debug_name): New function.

	for.
	
	* thread-db.c (stop_all_threads): Doc fixes.
	
	* aclocal.m4: Regenerated.
