Prefer TAP::Harness over Test::Harness
Prefer TAP::Harness over Test::Harness

TAP:Harness came along in perl 5.10.1, and since we claim to support
perl 5.10.0 in configuration and testing, we can only load it
conditionally.

The main reason to use TAP::Harness rather than Test::Harness is its
capability to merge stdout and stderr output from the test recipes,
which Test::Harness can't.  The merge gives much more comprehensible
output when testing verbosely.
