add a 'coverage' command to generate reports

Builds, runs and generates everything needed to have a coverage report
at the end for apt. The report isn't perfect as most childs apt forks do
not have a regular exit and so data is never written for them, which
results in e.g. most methods to have zero coverage reported.

\t$0 library
\t$0 buildlog filename…
»library« and »buildlog« aren't run automatically but can be useful for
maintaining the (more or less experimental) symbols files we provide.
»library« displays the diff between advertised symbols and the once provided
by the libraries, while »buildlog« extracts this diff from the buildlogs.
Both will format the diff properly.
\t$0 travis-ci
\t$0 coverage [output-dir]
»travis-ci« is a shortcut to install all build- as well as test-dependencies
used by .travis.yml.
»coverage« does a clean build with the right flags for coverage reporting,
runs all tests and generates a html report in the end.
