sip-in: default use-100rel to no
BulkVS servers act badly when we send a reliable 180 Ringing response
to an incoming call, even though they advertise 100rel support in
the Supported header in the INVITE packet, and we probably won't be
implementing 100rel for outbound because doing per-the-spec PRACK
as a UAC is just too burdensome. Therefore, we need to consider
100rel extension as not-really-supported in themwi-system-sw.
