Prior to this commit, a benchmark test could report 0..n passes and 0..m
fails or skips, where n is the number of accumulation iterations used to
collect benchmark data and m is the number of times the test function
was invoked. Depending on the type of benchmark measurer being used,
this could result in a very large volume of test output and inconsistent
pass, fail and skip counts between test runs.
This commit changes the behaviour so that each benchmark test reports
one pass, fail or skip, regardless of the number of iterations used to
collect benchmark data.
This commit also prevents benchmark data being reported in the test
output if the benchmark test failed or skipped, as any benchmark data is
of dubious value in such cases.
The latter change in behaviour requires a minor modification to the
badxml selftest, which now tests quoting of literal strings in xml test
output for both passing and failing benchmarks.
Finally, this commit also adds a new selftest specifically for verifying
correct behaviour for benchmarks that fail or skip.

For data-driven tests, testlib previously counted one fail or skip for
each data row that failed or skipped, while it counted only one pass
for a test function where all rows passed and counted no passes for a
test function where some rows passed and some rows failed. A similar
problem also existed for benchmark tests, which could run multiple
iterations of the same test, with each fail and skip being counted but
only a single pass being counted for the entire series of iterations.
This commit makes testlib count one pass, fail or skip for each data
row. Test functions that are not data-driven count one result for the
test function, as before. Benchmark tests count one pass, fail or skip
per iteration.
A side-effect of this change is that the test output in plain text, xml
and light xml formats now shows a result for every data row and
benchmark iteration executed, allowing post-processors to correctly
calculate the total number of tests executed. Previously, individual
rows were not shown in the test output if they passed, making such
calculations impossible.
The only change to the xunitxml output format is to correct a bug where
no test result was recorded for a test function if the last data row
was skipped and all other rows passed -- in which case the overall
result should be a pass. Note that there is also a pre-existing bug
in the xunit logger, where no result is reported if all rows are
skipped; that bug is unaffected by this commit.

Use a standard path for filenames that appear in the selftest's expected
test data. This will make future patches smaller.
