enable introspection support for upcoming introspection support for webkit-gtk.

Bump PKGREVISION.
Updated x11/gtk2 to 2.24.17nb3
Changes 5.5.32:
* mysql_upgrade now verifies that the server version matches the version against which it was compiled, and exits if there is a mismatch. In addiion, a --version-check option permits specifying whether to enable version checking (the default), or disable checking if given as --skip-version-checking.
* Bugs Fixed
Changes 2.0.8:

Perl 5.16.3's fix for a rehash-based DoS makes it more difficult to invoke
the workaround for the old hash collision attack, which breaks mod_perl's
t/perl/hash_attack.t. Patch from rt.cpan.org 83916 improves the fix
previously applied as revision 1455340.

On Perl 5.17.6 and above, hash seeding has changed, and HvREHASH has
disappeared. Patch to update mod_perl accordingly from rt.cpan.org 83921.

Restore build with Perl 5.8.1, 5.8.2 etc: take care to use
$Config{useithreads} rather than $Config{usethreads}, and supply definitions
of Newx and Newxz as necessary.

On Perl 5.17.9, t/apache/read2.t fails because an "uninitialized value"
warning is generated for the buffer being autovivified. This is because
the sv_setpvn() that's meant to vivify the buffer doesn't perform set
magic; the warning is generated by the immediately following SvPV_force().
Patch to fix this from rt.cpan.org 83922.

Fix t/perl/hash_attack.t to work with Perl 5.14.4, 5.16.3 etc, which
contain a fix for CVE-2013-1667 (memory exhaustion with arbitrary hash
keys). This resolves rt.perl.org 116863, from where the patch was taken.

use APR::Finfo instead of Perl's stat() in ModPerl::RegistryCooker to
generate HTTP code 404 even if the requested filename contains newlines

Remove all uses of deprecated core perl symbols.

Add branch release tag to 'make tag' target
Updated databases/mysql55 to 5.5.32; www/ap2-perl to 2.0.8
Add instruction to README at pkg_add or installation time.
Control the dependency on p5-GSSAPI via the 'gssapi' option. Still
on by default, so no PKGREVISION bump.
Override broken "configure" test that doesn't work with Perl 5.18.0
to fix the build of one of the helper scripts.

Bump the package revision because the binary package would have been
incomplete previously.
