This is the first patch of the series. The first two patches are
improvements of the log output and are independent of the 3rd patch in
terms of code - proposed logging improvements just make it easier to
debug issues with MNCC cause codes.

The code is also a part of the achemeris/mncc_cause_fixes_master branch.
