[PATCH] 4963723: Implement SHA-224

[Andrew Hughes]

Webrev: http://cr.openjdk.java.net/~andrew/jdk7u/4963723/webrev.02/
8 changeset: http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/3e3017eba8ac

This patch has been in IcedTea 2.x since the 2.5.3 release on
2014-10-14. We tried to push it upstream before but it got
blocked by Oracle leaving OpenJDK 7. It adds support for
SHA-224, a pre-requisite for backporting 7044060.

The 7 version is largely identical to the 8 version, and is
the same as the version in IcedTea 2.x. The main difference
is we don't add a new public variable SHA224 to
java.security.spec.MGF1ParameterSpec to avoid altering
the public API. The variable is just a shorthand
for new MGF1ParameterSpec("SHA-224") anyway and
we just use that in
com/sun/crypto/provider/OAEPParameters.java instead.

Ok to finally push?

Thanks,
