* tools/atc/README: Simplify instructions to use mysqlclient
tab-separated-values stdout, and remove obsolete manual steps which
have been automated.
* tools/atc/email-stats.sh: The functionality this shell script
previously provided has now been translated to Python and folded
into the inner script.
* tools/atc/email_stats.py: Implement the old email-stats.sh outer
loop, make it possible to run in a virtualenv, and make previously
hard-coded constants into command-line parameters with sane and
dynamically-determined defaults. Update field order and contents to
cope with differences in Gerrit 2.8, use a proper YAML parser on the
programs.yaml which has also changed format since the previous run,
and adjust for the improved extra-atcs file format as well.

* tools/atc/email-stats.py: Adjust the order in which Gerrit E-mail
addresses are returned so that the one listed as the preferred
address is sorted to the beginning of the set.

* tools/atc/email_stats.py: Move procedural code out of the global
scope to make this file safely importable, and clean up a couple of
unused variables flake8 noticed in the newly importable main
codeblock.

Rename tools/atc/email-stats.py to tools/atc/email_stats.py in
preparation for making it an importable module. This is being
separated from the subsequent change to make it more reviewable.
