Rename QAPIError to QAPISourceError, and then create a new QAPIError class that serves as the basis for all of our other custom exceptions, without specifying any class properties. This leaves QAPIError as a package-wide error class that's suitable for any current or future errors. (Right now, we don't have any errors that DON'T also want to specify a Source location, but this MAY change. In these cases, a common abstract ancestor would be desired.) Add docstrings to explain the intended function of each error class.
