Me thinks Craig had the right idea but perhaps not the
most correct solution. As currently structured, all of
the tests now go way too far by checking every 'unref'
and 'new' call when what we're trying for is survival.
In the final analysis, it doesn't matter who issues an
EXIT_FAILURE - that run_tests guy or an early Exit out
of a procps_new() function. They both will produce the
same end result of the desired "FAIL" test diagnostic.
[ and this patch once again allows the slabinfo test ]

The referenced commit introduced a test program for the API
but it would often fail due to:
The given pointer for _new() not being NULL
The return value for _new not checked, so the subsequent _unref()
would free() random memory
slabinfo checks failing due to permission denied errors.
The first two are fixed, as well as returning a fail to the test
if they don't return correctly, with slabinfo waiting to see if there
is a way of initialising the structure without reading the slabinfo.

This change sets the stage for exploiting the recently
added ITEMTABLE_DEBUG #define. All tests are performed
in a single module (after trying 6 separate programs).
The chances of each test detecting errors is extremely
remote (at least while I'm maintaining these modules).
However, this single program approach has one flaw and
it relates to the response whenever an error is found.
Each of those six new API modules calls Exit() if they
detect an error. Otherwise, incorrect results would be
produced at the least or an abend encountered at most.
This means that multiple 'make check' invocations will
be needed if more than 1 module actually was in error.
All in all, it is a small price for a large assurance.
