[PATCH] coccinelle: merge eight rules from strbuf.cocci

From: Markus Elfring <markus.elfring@web.de>

Message-ID: <31d2b9c8-31ec-4921-d38d-12712de819a7@web.de>

This script contained transformation rules for the semantic patch language which used similar code. Combine these rules by using two SmPL disjunctions so that the run time characteristics can be nicer because of common usage of a few metavariables.
