Summary:                    [patch] bug in parsing bearer capability
Description: 
I think there is a bug in receive_bearer_capability() in q931.c:

  data[] contains, the IE without the first two octets.
  pos is the pointer to an octed in data[]
  len is the length of the IE, including the first two octets.

Thus, if len is compared with pos, there is an offset of 2 which needs to
be fixed.

In dump_bearer_capability() it is handled correct (len -= 2;).

I just looked at the latest LibPRI 1.4 code and it appears this fix is
already in there.  Let me know if you still see a problem, though.
