rewrite coverage.sh

Browse source 
- multiple individual shell scripts instead of one 3.5k line monster
 - tests driven by Python script allowing:
    * declarative test description in coverage.txt
    * collecting errors instead of aborting on first error
    * skipping tests
    * running specific tests
