With -Wsign-compare, compilers warn about a mismatching signedness in
comparisons in various files in the tests/ directory.
For about half of the cases we can simply change the signed variable to
be of an unsigned type, because they will never need to store negative
values (which is the best fix of the problem).
In the remaining cases we can cast the signed variable to an unsigned
type, provided we know for sure it is not negative.
We see two different scenarios here:
- We either just explicitly checked for this variable to be positive
(if (rc < 0) FAIL();), or
- We rely on a function returning only positive values in the "length"
pointer if the function returned successfully: which we just checked.
At two occassions we compare with a constant "-1" (even though the
variable is unsigned), so we just change this to ~0U to create an
unsigned comparison value.
Since this is about the tests, let's also add explicit tests for those
values really not being negative.
This fixes "make tests" (but not "make check" yet), when compiled
with -Wsign-compare.

Two test programs - check_path and overlay - define a CHECK() helper macro
in such a way that in the case of an error it will re-execute the checked
code fragment, instead of using the return value from the initial call.
This can lead to misreporting errors, because the code may fail in a
different way the second time around due to changes made during the first
failing call.

Using 'index' as a local variable name shadows the standard library index()
function. This causes warnings on at least some compiler versions. The
recently added overlay code has a number of instances of this.
This patch replaces 'index' with 'poffset', since 'index' is being used to
mean "offset within a property value" in these cases.

Add some test infrastructure to test that the overlay can be merged, but
also that poorly formatted fixups would fail as expected.
