add/improve various logging

This logging turned up while I was debugging dynamic timeslots:
* OML Set Channel Attributes logging.
* a specific dyn TS pchan error.
* show pchan and lchan types on CHAN ACT ACK and REL ACK logging.
* move a dyn TS logging from DL1C to DRSL, where all the other dyn ts logging
  seems to be.
