Summary: This patch introduces new SB APIs for tracing support inside LLDB. The idea is to gather trace data from LLDB and provide it through this APIs to external tools integrating with LLDB. These tools will be responsible for interpreting and presenting the trace data to their users. The patch implements the following new SB APIs -> -> StartTrace - starts tracing with given parameters -> StopTrace - stops tracing. -> GetTraceData - read the trace data . -> GetMetaData - read the meta data assosciated with the trace. -> GetTraceConfig - read the trace configuration Tracing is associated with a user_id that is returned by the StartTrace API and this id needs to be used for accessing the trace data and also Stopping the trace. The user_id itself may map to tracing the complete process or just an individual thread. The APIs require an additional thread parameter when the user of these APIs wishes to perform thread specific manipulations on the tracing instances. The patch also includes the corresponding python wrappers for the C++ based APIs.
