This is a step towards getting rid of the __start_test_section and
__stop_test_section usage. The old macros assumed that all individual
variables assigned to the test section would be packed there as if in an
array. Mostly this seemed to work, too, with some magical alignment
fixes in the past. It was not guaranteed to work.
With the new test listing macros, we collect an actual array. The
drawback is that we need to mention all the test entry points explicitly
and they look like normal functions in the code - which they now are.
Their argument typing is safe, and their arguments are explicitly
visible. We rely on the compiler to complain about unused functions if
any entry point is forgotten from the array.
The array is still put into the test section, because this seems to be
the only feasible way of letting the harness code support both the old
and new test listing macros at the same time. This allows converting
each test program individually.
TESTFN_ARG() needs an explicit cast on the function pointer type,
because the data argument pointer type will not match const void*.
As an example of using the new macros, linalg-test.c is converted.

Add a status return value to every test definition. There are no
behavioral changes, previously the RESULT_OK was simply assumed.
The benefit of this is that in the future individual tests can also
return RESULT_SKIP, so that we can keep statistics of skipped tests.
ivi-layout-internal-test.c has the only case where a test function may
return early. That one is set to return RESULT_HARD_ERROR to match the
compositor exit code already there.
Also documentation is updated.

These are the same as linalg-4 cases, except the matrices have been
generated anew, and checked with Octave that the condition numbers and
determinant values hold.
