mod_http_oauth2: Correctly verify OAuth client credentials on revocation
Makes no sense to validate against username and password here, or using
a token to revoke another token, or itself?
In fact, upon further discussion, why do you need credentials to revoke
a token? If you are not supposed to have the token, revoking it seems
the most responsible thing to do with it, so it should be allowed, while
if you are supposed to have it, you should be allowed to revoke it.
