build coverage: make coverage numbers more accurate by using a baseline
The lcov tool offers the functionality to have an initial run over the code base before the tests are executed to make sure it catches all files, even the ones that are not loaded during the test run. This is something we missed so far. The reports have only been in relation to the files that actually have been loaded during the test. We missed quite a few files which made our numbers inaccurate. Things like modules/emotion/gstreamer1 have no tests yet and thus never showed up in the coverage report. While it has 103 functions and over thousand lines which need to get covered. With the baseline this is handled now. Thanks goes to the folks at LibreOffice who described their lcov setup here: https://wiki.documentfoundation.org/Development/Lcov New numbers are lower now as we count in all the files never loaded which decreases our percentages. Overall coverage rate: lines......: 30.2% (65119 of 215841 lines) functions..: 34.0% (6361 of 18733 functions) branches...: 23.6% (35627 of 151096 branches)
