DLM is using 1-to-many API but in a 1-to-1 fashion. That is, it's not needed but this causes it to use sctp_do_peeloff() to mimic an kernel_accept() and this causes a symbol dependency on sctp module. By switching it to 1-to-1 API we can avoid this dependency and also reduce quite a lot of SCTP-specific code in lowcomms.c. The caveat is that now DLM won't always use the same src port. It will choose a random one, just like TCP code. This allows the peers to attempt simultaneous connections, which now are handled just like for TCP. Even more sharing between TCP and SCTP code on DLM is possible, but it is intentionally left for a later commit. Note that for using nodes with this commit, you have to have at least the early fixes on this patchset otherwise it will trigger some issues on old nodes.
