After moving my asn1 dissector from 0.9.12 to 0.9.13 I found a
problem.

The changes in asn1.c from 1.18 to 1.19 contain a serious mistake.
Version 1.19 cannot correctly read bit strings any more. It does
not count the byte with the number of unused bits towards the
encoded length.  Thus after handling a bitstring, the datastream
is not synchronized any more.

Please apply the following patch.
