Subject: [PATCH] regex: Require PCRE 8.31

PCRE >= 8.31 is required for PCRE_INFO_MAXLOOKBEHIND usage, introduced
in commit 6fbb1463429748bed7ab6593779430ee1c0664f5 (2013/07).

regex can also make use of the PCRE_NO_AUTO_POSSESS feature from PCRE
8.34, but this is optional and properly guarded already.
