I found myself getting confused, thinking that proxy->send(cmd) sends a command to the proxy, when in fact it causes the proxy to send the command to the client. These are now named sendToClient, sendToServer and recvFromServer so that future readers (including my future self) will not make this mistake again.
Add a lot of comments to the debugger based on my current understanding of it. These may change in the future as we learn more, but they're helpful right now.
Also moved a few small things around in the code to clarify their purpose or scope. I.e., making a few things private, renaming a few functions, etc. No real logic changes, though. Also minor dead code removal. Also a few lint errors.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
