[SECURITY] Fedora 22 Update: pcre-8.37-2.fc22

Perl-compatible regular expression library. PCRE has its own native API, but a set of “wrapper” functions that are base d on the POSIX API are also supplied in the library libpcreposix. Note that this just provides a POSIX calling interface to PCRE: the regular expressions themselves still follow Perl syntax and semantics. The header file for the POSIX-style functions is called pcreposix.h.
