Indeed, but my idea was to do that in a separate patch set. I didn't want to blow up the current task.

When we want to use this SDP parsing in osmo-mgw, that likely triggers a rund of MGCP refactoring. I have plans there, being that we should be able to fully control SDP in MGCP messages instead of using the struct mgcp_conn_peer (so far a bit of a bottleneck for what we are able to express in SDP). That also has implications for osmo-bsc. So it is sort of a perpendicular other task with tails on it.

We could add an SDP lib in osmo-mgw without using it there... but:

To not get pulled into that and to not stretch this patch across git reposes, I thought of this as an SDP parsing incubator, and we can move to osmo-mgw (or libosmocore even) when it has matured.

I guess it has pretty much matured when this patch set gets accepted, and we can decide when to apply in osmo-mgw. Does that sound acceptable?
