Re: [tor-dev] Proposal 187: Reserve a cell type to allow client authorization

We reserve a new variable-length cell type, "AUTHORIZE."

We specify that any number of PADDING or VPADDING or AUTHORIZE cells may be sent by the client before it sends a VERSIONS cell. Servers that do not require client authorization MUST ignore such cells, except to include them when calculating the HMAC that will appear in the CLOG part of a client's AUTHENTICATE cell.

We still specify that clients SHOULD send VERSIONS as their first cell; only in some future version of Tor will an AUTHORIZE cell be sent first.

Sounds good to me. Feel free.
