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.

--- summary: Distrust servers with too small keys ... Introduction ============ This module sets the security status of s2s connections to invalid if their key is too small and their certificate was issued after 2014, per CA/B Forum guidelines. Details ======= Certificate Authorities were no longer allowed to issue certificates with public keys smaller than 2048 bits (for RSA) after December 31 2013. This module was written to enforce this, as there were some CAs that were slow to comply. As of 2015, it might not be very relevant anymore, but still useful for anyone who wants to increase their security levels. When a server is determined to have a "too small" key, this module sets its chain and identity status to "invalid", so Prosody will treat it as a self-signed certificate istead. "Too small" ----------- The definition of "too small" is based on the key type and is taken from [RFC 4492]. Type bits ------ ------ RSA 2048 DSA 2048 DH 2048 EC 233 Compatibility ============= Works with Prosody 0.9 and later. Requires LuaSec with [support for inspecting public keys](https://github.com/brunoos/luasec/pull/19).
