This provides an abstraction layer around TCP
sockets. Previously we just used fd integers, but
we don't want to be tied to integers for alternative
userspace TCP stacks.
Future patches will do more work to enable multiple
implementations of this abstraction. For now, just
get the abstraction in place for POSIX sockets and
make all of the iSCSI changes associated with it.

Splitting an iSCSI task into primary and sub tasks is complex
operation and a degradation was caused for it.
Hence adding test codes is required but there is no UT code for
it yet.
primary->bytes_completed is for read completion from bdev and
it is tested by this patch.
Additional test codes will follow:
- primary->bytes_completed is tested when read tasks do not
complete in order.
- primary->task.data_transferred is for write completion to
initiator through network.
- primary->task.data_transferred is tested by another patch
because primary->bytes_completed is used in iscsi/conn.c but
primary->task.data_transferred is used in iscsi/iscsi.c.
