Fixes encoding/decoding of transitive bit in extended communities

There is a trick: bit set means "not transitive".

   RFC4360:

        T - Transitive bit

-->         Value 0: The community is transitive across ASes

            Value 1: The community is non-transitive across ASes

This patch:
* factors out the code to packed community type and subtype
* avoids hardcoded 0x.. values in each ext com
* makes this code produce the right bit value for the transitive bit (applies only to RT at this point)
* fixes Origin ext com packing which was using wrong subtype (0x02 instead of 0x03)
