Jim Harris 4b10029435 net, iscsi: add struct spdk_sock abstraction
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.
