library/LAPDm_Types: add 'padding' field to the LapdmFrameAB record

TTCN-3 offers a very convinient way of matching an octetstring
against a record template (decoding target) on the fly, so that
there is no need to attempt decoding it manually beforehand.
This can be done by using the 'decmatch' keyword (see B.1.2.9).

Unfortunately, decmatch fails if an octetstring is longer than
the encoded variant of the decoding target (e.g. has padding).
Let's work this around by adding a 'padding' field, so during
decoding all remaining octets will be stored in it.
