Merged r8195:8205 from jcorgan/ecc into trunk. Adds convolutional encoder
and decoder corresponding to the R=1/2, K=7 CCSDS standard ("Voyager").

This code is a GNU Radio wrapper around a 1995-era KA9Q portable-C
implementation, and is designed for continuous streaming data, not packets....

Mostly fixed the van de Beek ML synchronization scheme. Instead of using the CP timing signal, it correlates against the known preamble just to send along the timing trigger. This works nicely and keeps the frequency more constant in the receiver since it updates the estimate every received symbol. Read the comments inside to see why it's 'mostly fixed' -- this was mostly proving a point for myself today....

Adjusting structure a bit to redistribute responsibilities. This does not change the behavior or performance at all. The sync. block only calculates the frequency and timing signals and now outputs the fine frequency adjustment signal from output 0 and the timing signal for the start of the packet from output 1....
