Subject: anv/entrypoints: Allow an entrypoint to require multiple extensions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In this case, we say an entrypoint is supported if ANY of the extensions
is supported.  This is because, in the XML, entrypoints don't require
extensions so much as extensions require entrypoints.
