Changes in v3: * There were some comments about how the protocol should be designed stateless first. I've made this change and instead of having to supply the `stateless-rpc=true` capability to force stateless behavior, the protocol just requires all commands to be stateless.* Added some patches towards the end of the series to force the clientto not request to use protocol v2 when pushing (even if configured to use v2). This is to ease the roll-out process of a push command in protocol v2. This way when servers gain the ability to accept pushing in v2 (and they start responding using v2 when requests are sent to the git-receive-pack endpoint) that clients who still don't understand how to push using v2 won't request to use v2 and then die when they recognize that the server does indeed know how to accept a push under v2. * I implemented the `shallow` feature for fetch. This feature encapsulates the existing functionality of all the shallow/deepen capabilities in v0. So now a server can process shallow requests. * Various other small tweaks that I can't remember :) After all of that I think the series is in a pretty good state, baring any more critical reviewing feedback.

I inspected the diff between v2 and v3 and found the changes to be good. Reviewed-By: Derrick Stolee <dstolee@xxxxxxxxxxxxx> Thanks, -Stolee
