Cleaned up some of the superfluous variations of onServer*()/onClient*() in the debugger commands. The separation was a leftover of the days when we had the VM and the compiler. The entire DebuggerCommand interface, what's public/protected/private, etc. could use a serious cleanup, but I'm not going that far now. I mostly wanted to clean this up to make some other work we need to do server-side less complicated.
Hphpd's Jump command has been fundamentally broken for a long time. It was originally implemented to run the byte code in a modified way which didn't make state changes, and wait for the destination offset to be reached. We lost the ability to do that long ago, and the implementation of this command has atrophied since. As it stands now, if you're lucky it might act like "run until", which is the opposite of what it is documented to do.
I've removed the command entirely. Fixing it is a very large effort which we might consider some time in the future.
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.
