Add TestThreadAPI.py file to house the Python SBThread API test cases.
Currently it has only test cases for SBThread.GetStopDescription() API. Also modified lldb.swig to add typemap for (char *dst, size_t dst_len) which occurs for SBThread::GetStopDescription() C++ API. For Python scripting: # Due to the typemap magic (see lldb.swig), we pass in an (int)length to GetStopDescription # and expect to get a Python string as the result object! # The 100 is just an arbitrary number specifying the buffer size. stop_description = thread.GetStopDescription(100) llvm-svn: 127173
