When debugging a script using a local VM (i.e. when there is no remote VM),
the cleanup actions performed by the run command caused the debugger client
to shut down as well. Since this seems to be intentional, processing of the
run command now restarts the debugger client and proxy. Also, following a
ctrl-C, the m_lastLocFilter field must be cleared, otherwise an empty endless
loop cannot be broken into for a second time.
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.
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.
