[DLM] Consolidate transport protocols
This patch consolidates the TCP & SCTP protocols for the DLM into a single file
and makes it switchable at run-time (well, at least before the DLM actually
starts up!)
For RHEL5 this patch requires Neil Horman's patch that expands the in-kernel
socket API but that has already been twice ACKed so it should be OK.
The patch adds a new lowcomms.c file that replaces the existing lowcomms-sctp.c
& lowcomms-tcp.c files.

- The DLM Can use TCP or SCTP for it's network communications.
- SCTP supports multi-homed operations whereas TCP doesn't.
- However, SCTP seems to have stability problems at the moment.
