monitor.c: Don't install a deprecated_xfer_memory method. 

This removes another yet instance of a deprecated_xfer_memory user.

Tested by building a --enable-targets=all gdb, on x86-64 Fedora 17.

2013-10-09  Pedro Alves  <palves@redhat.com>

	* monitor.c (monitor_write_memory, monitor_write_memory_bytes)
	(monitor_write_memory_longlongs, monitor_write_memory_block):
	Constify 'myaddr' parameter.
	(monitor_xfer_memory): Adjust interface as monitor_xfer_partial
	helper.
	(monitor_xfer_partial): New function.
	(init_base_monitor_ops): Don't install a deprecated_xfer_memory
	hook.  Install a to_xfer_partial hook.
