mod_http_oauth2: Limit revocation to clients own tokens in strict mode
RFC 7009 section 2.1 states:
> The authorization server first validates the client credentials (in
> case of a confidential client) and then verifies whether the token was
> issued to the client making the revocation request. If this
> validation fails, the request is refused and the client is informed of
> the error by the authorization server as described below.
The first part was already covered (in strict mode). This adds the later
part using the hash of client_id recorded in 0860497152af
It still seems weird to me that revoking a leaked token should not be
allowed whoever might have discovered it, as that seems the responsible
thing to do.
