abstract transport to static driver functions and opaque driver specific information.

Browse Source 
This splits a transport into static driver specific functions for the common
iscsi commands. Optionally, a driver specific opaque memory is introduced
which is currently only used by iSER transport.
Last a lot of functions changed to static.
