* linux-low.c (linux_read_memory): Change return type to

	int.  Check for and return error from ptrace().
	* target.c (read_inferior_memory): Change return type to int.  Pass
	back return status from the_target->read_memory().
	* target.h (struct target_ops): Adapt *read_memory() prototype.
	Update comment.
	(read_inferior_memory): Adapt prototype.
	* server.c (main): Return an error packet if
	read_inferior_memory() returns an error.
