	gdb/gdbserver  : ChangeLog linux-low.c linux-x86-low.c 
	                 mem-break.c mem-break.h server.h 

Log message:
	* linux-low.c (linux_wait_1): Avoid setting need_step_over is
	there's a GDB breakpoint at stop_pc.  Always report a trap to GDB
	if we could tell there's a GDB breakpoint at stop_pc.
	(need_step_over_p): Don't do a step over if we find a GDB
	breakpoint at the resume PC.
	
	* mem-break.c (struct raw_breakpoint): New.
	(enum bkpt_type): New type `gdb_breakpoint'.
	(struct breakpoint): Delete the `PC', `old_data' and `inserted'
	fields.  New field `raw'.
	(find_raw_breakpoint_at): New.
	(set_raw_breakpoint_at): Handle refcounting.  Create a raw
	breakpoint instead.
	(set_breakpoint_at): Adjust.
	(delete_raw_breakpoint): New.
	(release_breakpoint): New.
	(delete_breakpoint): Rename to...
	(delete_breakpoint_1): ... this.  Add proc parameter.  Use
	release_breakpoint.  Return ENOENT.
	(delete_breakpoint): Reimplement.
	(find_breakpoint_at): Delete.
	(find_gdb_breakpoint_at): New.
	(delete_breakpoint_at): Delete.
	(set_gdb_breakpoint_at): New.
	(delete_gdb_breakpoint_at): New.

	(uninsert_breakpoints_at): Adjust to handle raw breakpoints.
	(reinsert_raw_breakpoint): Change parameter type to
	raw_breakpoint.
	(reinsert_breakpoints_at): Adjust to handle raw breakpoints

	(check_mem_read): Adjust to iterate over raw breakpoints instead.
	Don't trust the breakpoint's shadow if it is not inserted.
	(check_mem_write): Adjust to iterate over raw breakpoints instead.
	(delete_all_breakpoints): Adjust.
	(free_all_breakpoints): Mark all breakpoints as uninserted, and
	use delete_breakpoint_1.
	
	* mem-break.h (breakpoints_supported): Delete declaration.
	(set_gdb_breakpoint_at): Declare.
	(gdb_breakpoint_here): Declare.
	(delete_breakpoint_at): Delete.
