1) Remove all our PDU code and switch to the PDU code from the
klinker library
2) Switch to using the system Lollipop MMS library by default,
and falling back to our own custom library if that fails.
3) Format SMIL differently, using code from klinker instead of
what we've pieced together.
4) Pull per-carrier MMS media constraints from the XML config
files in the klinker library, instead of hardcoding it at 280kb.
Hopefully this is an improvement, but given that MMS is involved,
it will probably make things worse instead.
1) Utilize the hidden API requestRouteToHostAddress that takes an
InetAddress (IPv6-capable) instead of a forced IPv4 integer-
encoded address. Will fallback to the IPv4 one if reflection
fails for whatever reason.
2) If on Lollipop and our manual MMS code doesn't work, will try
to use the Lollipop API and give it 60 seconds instead of 30,
since I did run into the timeout not being long enough in
certain conditions and I'm thinking maybe it just wasn't long
enough for some carriers.
