Add separate TCAP decoder that is not linked to MAP
this way we can parse only the TCAP layer into dialogue portion
and component portion, but without actually parsing those.

+-- This is a manually-crafted simplified TCAP ASN.1 syntax, created
+-- for the signerl project by Harald Welte <laforge@gnumonks.org>
+--
+-- The "problem" with the real TCAP spec is its use of templates,
+-- which is nice if you want to create a fully integrated TCAP + MAP
+-- decoder, but in this case we simply want to parse all the common
+-- parts and ignore the application-specific parameters/rsults of the
+-- respective operation.
