Better report too large pack-files from PushCommand
JGits PushCommand and BasePackPushConnection were throwing generic TransportExceptions when the pushed pack-file was rejected by the server since it was too big. Let JGit better interprete the server's response to detect this situation and throw a more specific exception. This detection works by parsing the status line sent by the server. This change only recognizes the response sent by a JGit based server. All other servers which report such problems in a different way still lead to a generic TransportExceptions.
