L1CTL: Add message segmentation helper via getMsgLen()
As L1CTL is using a stream socket, we need to give the UNIX_DOMAIN
port some clue as to where our L1CTL message boundaries are in the
stream.
This requires a patched UNIX_DOMAIN_SOCKETasp test port with the
following commit applied:
commit 655cb4ab2ac006b3a73d1b679c83081d9743410a
Author: Harald Welte <laforge at gnumonks.org>
