Add --enable-coverage configure option
This configure flag enables lcov [1] coverage generation and is intended
to be used with unit tests (--enable-unit-tests is implied).
A html coverage report can be generated by issuing the following command
in the toplevel build directory:
make coverage
[1] - http://ltp.sourceforge.net/coverage/lcov.php
Based on a patch by Adrian-Ken Rueegsegger.
