Initial support for target names

blockd will now only accept requests based on the target name (ie only for the
file it has opened), and will return an XS_ERROR reqeust otherwise.

xsegbd will now take a target name as an argument when adding a device via...

xq: Fix iteration bug in xq_head_to_tail()

Since __xq_pop_head() decrements head to point to the (new) first
available item in the queue, xq_head_to_tail() should iterate headq
forward (by incrementing head), not backwards. Backward iteration
results in xq corruption, which can easily be triggered using...

fix broken xq_head_to_tail()

used by xseg_free_requests(),
bug exposed by add/remove device tests by psomas.

Also, refactor so that __xq_append_tail() returns
the index to the leftmost (least) side of the queue buffer,
as is the convention with all other 3 functions...

Merge wip-sysfs into xseg, with amendments

Conflicts:
xseg/sys/xsegbd.c

Amendments:
struct completion is now per-request, not per-device.
The xsegbd callback (heuristically) knows when
xreq->priv is an index of an I/O request or a pointer
to a completion struct, and branches out accordingly....

Simplify callback req demultiplexing (temp).

Until prepare_wait() is fixed to support an extra
argument, we can manually assign port.waitcue to the address of the
appropriate xsegbd_device struct before submitting the request,
simplifiying the callback request demultiplexing (don't iterate...
