rewrite make-target-delegates matching code

This patch rewrites the make-target-delegates matching code a little
bit.  The result is functionally the same (the output has some small
whitespace differences), but the new code is more forgiving regarding
the formatting of target.h.  In particular now there's no need to
ensure that the return type and the method name appear on the same
line.

2014-07-23  Tom Tromey  <tromey@redhat.com>

	* make-target-delegates ($ARGS_PART): Match trailing close paren.
	($INTRO_PART): Don't match whitespace.
	($METHOD_TRAILER): Move earlier.  Remove trailing semicolon and
	argument matching.
	($METHOD): Add $METHOD_TRAILER.
	(trim): Rewrite.
	(scan_target_h): New sub.
	Change main loop not to collect state.
	* target-delegates.c: Rebuild.
