Add regexp regression tests

- Bug 757711: heap-buffer-overflow in xmlFAParsePosCharGroup
  <https://bugzilla.gnome.org/show_bug.cgi?id=757711>
- Bug 783015 - Integer-overflow in xmlFAParseQuantExact
  <https://bugzilla.gnome.org/show_bug.cgi?id=783015>

(Regexptests): Add support for checking stderr output when
running regexp tests.  This makes it possible to check in test
cases that fail and not see false-positive error output when
running the tests.  Unlike other libxml2 test suites, if there
is no stderr output, no *.err file needs to be created.
