adding support to FCoE transport

This is the RFC v2 of adding fcoe transport to support vendor specific FCoE
transport into the existing Open-FCoE framework.

v1:
Initial post for adding fcoe transport:
https://lists.open-fcoe.org/pipermail/devel/2010-December...
Follow-up comments & discussions:
https://lists.open-fcoe.org/pipermail/devel/2011-January/...

v2:
1. Per Joe's comment, renamed the libfcoe_fip.c to be fcoe_ctlr.c. I
also renamed the new ibfcoe_transport.c to be fcoe_transport.c.
2. Per Bhanu's comment, I have merged the three follow-up patches
from Bhanu with the following changes in fcoe_parse_buffer():
a) Though not a problem of the existing fcoe-util since the sysfs
entry is changing to libfcoe anyway, I still want to fill the buffer
of drv_name with default "fcoe" so default behavior is still the same
w/o changing cfg-ethx.
b) Fixed the '\n' ending in the input buffer in fcoe_parse_buffer, we still
need that proper formatting logic from the original fcoe_if_to_netdev(),
otherwise the ifname and drv_name will be messed up, causing the lookup for
netdev and transport to fail.

Testing Notes:
Did the checkpatch and tested w/ overnight stress FCoE traffic on 2 LUNs using
fcoe.ko as the default fcoe transport, that seems to be working ok. However,
loop create/destroy testing is needed before this gets committed eventually.

thanks,
