SSL for the bzr protocol

[Denys Duchier]

On LaunchPad, I made the following "merge proposal": Provide SSL
encrypted communication for the bzr protocol.

server::

    bzr serve --keyfile FILE --certfile FILE ...

client::

    bzr log bzrs://host/branch

These are the merge proposals in reversed chronological order:

https://code.launchpad.net/~denys.duchier/bzr/bzr.ssl/+merge/10175
https://code.launchpad.net/~denys.duchier/bzr/bzr.ssl/+merge/10163
https://code.launchpad.net/~denys.duchier/bzr/bzr.ssl/+merge/10147

I am currently working on:

    - STARTTLS-type encryption initiation
    - user authentication (through plugins)
    - operation authorization (through plugins)

for the bzr protocol.

Cheers,
