The separation between these classes was a vestige of days gone by. Combined them. I ran into issue with having the proxy split up in particular when working on stepping, so doing this now as a separate diff to keep things cleaner.
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.
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.
If you allocate a StringData on the stack, and it escapes,
you're in trouble. Make the destructor assert by default,
and add a StackStringData which does the appropriate
refCounting and checking.
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.
