v1 -> v2:
- Addressed comments from v1 (from both Darrell and Mark, thanks!);
- Added support for UDP;
- Added tests for each supported transport, UDP and TCP, and some more
  individual tests for testing particular functions (around parsing and
  framing).

A couple of points worth mentioning in v2:
- Support for TCP framing, in patch 4/6, is not yet optimal as it
  dismisses SIP messages that span across multiple TCP packets. I plan
  to focus on that next;
- Patches 2/6 and 3/6 are independent (can be applied separately of this
  patchset) and provide some flexibility for protocols such as SIP. More
  details in each separate patch.

Regards,

Tiago
