Rationalize NA contest mode

Generic message packing and unpacking routines now understand antipode
grid contest messages.  These messages  are now recognized as standard
messages in  message response processing and  dealt with appropriately
when contest mode is selected and applicable (currently FT8 and MSK144
only).

Fix issues with type 2 compound calls in contest mode

Message generation in  contest mode now generates the  correct Tx3 for
type 2 calls.

"<type-2> 73"  is a free  text so  needed special handling  in message
processing.

Improved message generation for type 2 calls in contest mode

These attempt  to ensure that  a prefix is  logged by the  QSO partner
even if the compound call holder user Tx3 to tail-end a QSO.

The  type  2 message  generation  options  are largely  overridden  in
contest mode as only a few options make sense. Key is that Tx1 may use
only the base call when calling split is necessary, this requires that
both Tx3 and Tx4 have the full compound call otherwise the QSO partner
will never see the  full call until it is possibly  too late i.e. post
logging.

Fix erroneous auto stop critera for auto reply in FT8

We cannot assume that a "DE <dx-call>  <anything>" is or is not for us
so  we must  continue calling  and  risk possible  QRM. Calling  split
avoids this issue.

c5dfd9c9b7 Fix an error in SNR_2500 scaling and add calculation of probability of decode vs number of hard errors.

f64cfb68ec Bring ldpcsim40.f90 up to date and add coherent averaging option to both ldpcsim144 and ldpcsim40. These routines simulate only the performance of the code and the hash/CRC.

808259b7bf Add early termination code to the msk144 long-message decoder. Remove references to Radford Neal's ldpc code, which served us well but is no longer needed.
