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

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

[Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 12 Nov 2019 17:50:13 +0100

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.
