Updated x11/gtk3 to 3.10.7
Set minimum required API version of OpenSSL to 1.0.1c:
1.) OpenSSL 0.9.8* doesn't support TLS 1.2, Elliptic curve cryptography
    and other modern TLS features.
2.) Supporting OpenSSL 0.9.8* causes extra maintenance overhead.

As a result NetBSD 5.*, all versions of Mac OS X and possibly other
platforms will now use OpenSSL from "pkgsrc".
Recursive PKGREVISION bump for OpenSSL API version bump.
Recursive PKGREVISION bump for OpenSSL API version bump.
Remove work-around for OpenSSL 0.9.9 snapshot distributed with NetBSD 5.*.
Undo undesired ABI version bump done by "blbump" script.
Remove now unnecessary package list handling for OpenSSL 0.9.*.
