Add streaming method profiling support.
The goal is to allow DDMS to start/stop method profiling in apps that
don't have permission to write to /sdcard. Instead of writing the
profiling data to disk and then pulling it off, we just blast the whole
thing straight from memory.
This includes:
- New method tracing start call (startMethodTracingDdms).
- Rearrangement of existing VMDebug method tracing calls for sanity.
- Addition of "vector" chunk send function, with corresponding
update to the JDWP transport function.
- Reshuffled the method trace start interlock, which seemed racy.
- Post new method-trace-profiling-streaming feature to DDMS.
Also:
- Added an internal exception-throw function that allows a printf
format string, so we can put useful detail into exception messages.
For bug 2160407.
