New versions of gcc reasonably warn about the odd pattern of
strncpy(p, q, strlen(q));
which really doesn't make sense: the strncpy() ends up being just a slow
and odd way to write memcpy() in this case.
Apparently there was a patch for this floating around earlier, but it
got lost.

Like others test are doing print the gathered statistics after test module
is finished. Return from the module based on the result.

Currently the only one combination is tested for overflow, i.e. rowsize =
16, groupsize = 1, len = 1. Do various test to go through all possible
branches.

After processing by hex_dump_to_buffer() check all the parts to be expected.
Part 1. The actual expected hex dump with or without ASCII part.
Part 2. Check if the buffer is dirty beyond needed.
Part 3. Return code should be as expected.
This is done by using comparison of the return code and memcmp() against
the test buffer. We fill the buffer by FILL_CHAR ('#') characters, so, we
expect to have a tail of the buffer will be left untouched. The
terminating NUL is also checked by memcmp().

Better to use memcmp() against entire buffer to check that nothing is
happened to the data in the tail.

The magic numbers of the length are converted to their actual meaning,
such as end of the buffer with and without ASCII part.
We don't touch the rest of the magic constants that will be removed in the
following commits.

Define a character to fill the test buffers. Though the character should
be printable since it's used when errors are reported. It should neither
be from hex digit [a-fA-F0-9] dictionary nor space. It is recommended not
to use one which is present in ASCII part of the test data. Later on we
might switch to unprintable character to make test case more robust.

The test suite currently doesn't cover many corner cases when
hex_dump_to_buffer() runs into overflow. Refactor and amend test suite
to cover most of the cases.
This patch (of 9):
Just to follow the scheme that most of the test modules are using.
There is no fuctional change.
