New sync task for calypso BTS, using a single frame per multiframe
By using single frame only, loss of packets is reduced. For normal data
frames (and for TCH/H speech), one out of four parts of data gets lost.
For TCH/F speech, only one out of eight parts of data gets lost. The error
correction can compensate the missing parts.
The sync code can use the extended DSP task, but it is currently disabled,
because the current DSP code does not allow scheduling TSC for each
individual task, but we need to use TSC of sync cell here.
