In runCommand() the send() and recv() can fail and raise BrokenPipeError and EOFError exceptions when the bitbake-server is unexpectedly terminated. In these cases a python traceback is currently dumped. Similarly updateFromServer() which calls runCommand() can also raise these and other exceptions, and currently lacks proper exception handling resulting in python traceback. We wrap calls to runCommand() and updateFromServer() in a try/except block as well as improve the exception handling for updateToServer(). This along with the earlier commit which added text to the BrokenPipeError and EOFError exceptions in runCommand() to indicate a bitbake-server termination may have occurred, should improve the user's ability to understand and handle these errors. An easy way to trigger each of the runCommand() exceptions is to 'kill -9' bitbake-server before (causes EOFError) or after (causes BrokenPipeError) the "Loading Cache" stage.
