dlm: Consolidate TCP & SCTP protcols

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.

Here's a revised version of that patch (as requested) that puts all the code into lowcomms-tcp.c rather than creating a brand new file.

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!)

I've changed the Makefile to refer to lowcomms.c rather than lowcomms-tcp.c so you will need to rename the file once its in git

Hi,

Now in the git tree. Thanks,

Steve.

Dave, if you get time, it would be nice to have dlm_controld read a parameter from ccs to control this...
