This feature has been designed with the sometimes quite flakey direct
(parallel or serial port attached) bitbang programming adapters in
mind that were quite common about two decades ago.
With parallel ports vanishing from modern PCs almost completely, and
the advent of various USB-attached low-cost programming devices,
this class of programmers disappeared almost completely.
Furthermore, the fuse combinations that were covered by the feature
are no longer around on all recent AVR devices, so for an ever
increasing number of devices, safemode already became meaningless and
was turned off anyway.
With the prospective version 7.x release, it's a good point in time to
introduce a major change like this one.
For one, this allows us to use MSG_DEBUG in order to emit debug
messages (requires -v processing).
As another effect, if the -C conffile option was given, there is no
need at all to run through all the process of looking up a system
config file - it's right there already.
Also, move it after the logfile creation if -l logfile was given, so
the respective debug message can go to the logfile.

* Update 'src/doc/avrdude.texi' to reflect the new search method for 'avrdude.conf'
