Z packet change

[Mark Salter]

The following patch changes the Z packet support for hw breakpoints to
match the documentation. Its not clear to me if we should do this or
change the documentation to make make the 'len' field optional. Some
hw lets you specify a range for hw breakpoints and although gdb doesn't
support that right now, it may in the future.

	* remote.c (remote_remove_hw_breakpoint): Add 'len' field to Z packet.
	(remote_insert_hw_breakpoint): Ditto.
