APR Test Coverage

This should give us some idea of how well our tests actually stress our code. To generate this data, do the following:

./buildconf

CFLAGS="-fprofile-arcs -ftest-coverage ./configure

make

cd test

make

./testall

cd ..

make gcov

Note that this will only generate test coverage data for the testall script, but all tests should be moving to the unified framework, so this is correct.
