Integrity Transform Carrying Roll-Over Counter for SRTP

Once debugged, it should provide a simple way to synchronize live
(multicast...) secure streams.

- Require automake 1.9 to fix some libtool plugin build problems
- Remove useless libs/Makefile

This is not very useful at the moment, but will be needed for proper

It has to be at least 64, and it is too complicated to implement a bigger
value, so it's not going to be configurable
