Adding support to fcoe transport

This is v3 of the series to add fcoe transport as a thin layer to the
existing Open-FCoE framework to allow third-party FCoE HBA drivers to
plug in easily if the default SW HBA fcoe.ko driver is sufficient for
the need. Related previous discussion are in the following threads:
RFC v1:
https://lists.open-fcoe.org/pipermail/devel/2010-December...
https://lists.open-fcoe.org/pipermail/devel/2011-January/...

RFC v2:
https://lists.open-fcoe.org/pipermail/devel/2011-January/...

Notes on v3:
1. Included 2 of Bhanu's ERESTARTSYS patches as patch 9 and 10.
2. Synced up w/ Open-FCoE's fcoe-next/master, so this series should apply
and build cleanly.
3. Did loop create-> i/o -> destroy test using default transport on
fcoe.ko, with the help from Bhanu on testing this framework using his
fcoe transport driver. 
4. Corresponding changes on fcoe-utils are required to reflect the above
changes, which I expect to follow soon.
