* lib/gdb.exp (gdb_test): Between $pattern and $prompt, expect

only \r\n, not .*.  The test can pass .* as the last thing in
	$pattern if that is what it wants.  In addition to providing this
	flexibility, this change should speed up pattern matching in cases
	where the pattern already ended with .* (there were a number of
	them).  This change also helps catch bad patterns--in the old
	scheme the typo "char \*" instead of "char \\*" would pass.  Now
	it is caught.
	* Many .exp files: Update callers.
