This implements the interactive trace start and stop methods. This diff ended up being much larger than I anticipated because, by doing it, I found that I had implemented in the beginning many things in a non optimal way. In any case, the code is much better now. There's a lot of boilerplate code due to the gdb-remote protocol, but the main changes are: - New tracing packets: jLLDBTraceStop, jLLDBTraceStart, jLLDBTraceGetBinaryData. The gdb-remote packet definitions are quite comprehensive. - Implementation of the "process trace start|stop" and "thread trace start|stop" commands. - Implementaiton of an API in Trace.h to interact with live traces. - Created an IntelPTDecoder for live threads, that use the debugger's stop id as checkpoint for its internal cache. - Added a functionality to stop the process in case "process tracing" is enabled and a new thread can't traced. - Added tests I have some ideas to unify the code paths for post mortem and live threads, but I'll do that in another diff.
