library: Initial work on GPRS RLC/MAC encoder/decoder
...
For Downlink and Uplink RLC/MAC Control blocks this is already working
quite nicely. Data blocks is not working, as their encoding cannot be
expressed in TTCN-3 RAW syntax, and a mixture of C++/native and
RAW-generated coder will be required.

don't match on L1CTL SAPI in received frames
...
L1 has no idea about the SAPI encoded in LAPDm when it passes a
PH-DATA.ind up to us. So dont match on that L1CTL field, only match the
SAPI we decoded from LAPDm header.

Add new LAPDm RAW port
...
This is a Test Component which sits on top of L1CTL (which in turn is on
top of the Unix Domain Socket Test Porrt). It performs LAPDm message
encoding/decoding, so we can use the regular send() / receive() methods
and associated template matching to send/receive/match LAPDm in a
comfortable way.

LAPDm_Types: re-order fields of LapdmCtrl definitions
...
for some reason, the "TAG()" matic of TITAN RAW decoder seems to fail
when we use FIELDORDER(msb) and match on a field that's not the first
field of the sub-record :/
Re-ordering the fields into LSB order seems to resolve this.

l1ctl/lapdm test infrastructure: Move helper functions out
...
moving all templates into L1CTL_Types as well as helper functions into
L1CTL_PortType allows us to have a clean L1CTL_Test.ttcn where we can
focus on actual test cases. At the moment it's just a PoC that can
establish dedicated mode and send a SABM frame to the BTS, which is
properly echo'ed back in the UA, as expected for contention resolution.

first steps towards a L1CTL / LAPD test

The idea here is to implement the L1CTL protocol in TTCN-3 so we can
speak it over a unix domain socket (test port) for simple tasks such as
activating dedicated mode.
This can then subsequently be used for LAPDm testing
