Add stat items for the BTS's channel load average and T3122.

In addition to logging the current values of a BTS's channel load
average and T3122 override, maintain stat items for these values.
This allows for plotting these values over time, for instance.

These values show up in the VTY under 'show stats' like this:

base transceiver station:
 Channel load average.:       25 %
 T3122 IMMEDIATE ASSIGNMENT REJECT wait indicator.: 32 s
