bsg: Remove unused function bsg_goose_queue()
The function bsg_goose_queue() does not have any in-tree callers,
so let's remove it.

block: drop custom queue draining used by scsi_transport_{iscsi|fc}
iscsi_remove_host() uses bsg_remove_queue() which implements custom
queue draining. fc_bsg_remove() open-codes mostly identical logic.
The draining logic isn't correct in that blk_stop_queue() doesn't
prevent new requests from being queued - it just stops processing, so
nothing prevents new requests to be queued after the logic determines
that the queue is drained.
blk_cleanup_queue() now implements proper queue draining and these
custom draining logics aren't necessary. Drop them and use
bsg_unregister_queue() + blk_cleanup_queue() instead.

block: Change module.h -> export.h in bsg-lib.c
This file isn't using full modular functionality, and hence
can be "downgraded" to just using the export.h header.

bsg-lib: add module.h include
Due to conflicts with the moduleh tree in linux-next, we
run into an include file mess. We really need export.h
in that tree, but if we add module.h locally then the
issue is easier to resolve.

block: add bsg helper library
This moves the FC classes bsg code to the block layer and
makes it a lib so that other classes like iscsi and SAS can use it.
It is helpful because working with the request queue, bios,
creating scatterlists, etc are a pain that the LLD does not
have to worry about with normal IOs and should not have to
worry about for bsg requests.
