Turn some blackbox tests into API tests.

Different test executables can run in parallel, whereas the functions
within one test executable cannot. This means that tst_blackbox is
currently a bottleneck, as it takes an order of magnitude longer
than all other tests combined. We therefore turn a number of blackbox
tests into API tests (most tests work equally well in either).
The run-time of these two test executables is now about the same, and as
a result, the time it takes to run "make check" has almost halved.
