Richard Mudgett dcd62e467f Add COLP support to libpri for ETSI PTP, ETSI PTMP, and Q.SIG. 
Add Connected Line Presentation (COLP) support to chan_dahdi/libpri as an
addition to issue 8824.  This is the libpri portion.  COLP support is now
available for ETSI PTP, ETSI PTMP, and Q.SIG with this patch.

(closes issue #14068)
