Add pri_new_bri_cb() API - Create BRI D-channel with user defined I/O callbacks and data

Browse Source 
There currently exists a pri_new_cb() API call that allows you to create a
PRI with user-defined I/O read and write callbacks, and option userdata.

Add the same capability for BRI interfaces by adding a pri_new_bri_cb()
API function.

(closes issue #16477)
