91f1b4bc6f Added router command values: they will be used: 
- as command types in protocol modules (standard routing or session change routing)
- to write back the data from backend (discard multiple backends ouput)

17e33d2ef9 Added command type to: 
gwbuf struct
dcb struct

This int field will hold the last command executed or sent to backend.

It will be 0 for most cases, setting it with a different value could help route differently the data from backend to client or some custom error messages.

aea8af08ba Fixes to enable multiple gateways to be run on the same machine. 
A temporary directory is used for the data directory, incorporating the pid
in the directory name. If set then the data directory will be stored in $GATEWAY_HOME,
if not it will be placed in /tmp

If $GATEWAY_HOME is set then the log files will be written to $GATEWAY_HOME/log
