Rather than timeout, explicitly disable tests_pass_valgrind and
tests_compile_coverage.  This is important now we run under valgrind
the first time we run the tests, thus would always time out and not
run most of the tests at all!

"make check" takes 7m57s, old "make fastcheck" takes 3m28s, and this takes
only 1m57s, but much more is run (as shown by the larger score total).

Putting the reduced config.h in the current directory means that it's
actually being picked up by other tests, such as the string checks.
So move it to a sub-directory where we need an explicit -I.

We also fix the dependencies, so that "--target
tests_pass_without_features" works.

Tests can be slow to run, and this way we can monitor progress.

We eliminate dependencies as we recurse, but if a single _info file
lists a dependency twice, we add it to the list twice and this skip
over the middle ones.

Rather than a separate cov_compiled member, we can add to the
compiled[] array, and we reduce duplication significantly.

Rather than mug the old ->compiled version when we reduce features,
keep both in the structure.  This makes it clear that we are using the
right version (we weren't in all cases, in particular we weren't
recompiling the test helpers correctly.

Unless it's not available or suppressed, we might as well run it under
valgrind the first time, which speeds things a little.

We save the valgrind output file for tests_pass_valgrind's use later.

We'll need this in a moment.

There's no reason to hand in the name of the compiled _info file,
since we don't compile it up in safe mode.

Trivial cleanup, but differentiates from the general obj_list used
elsewhere.

When an open() call fails, we don't inject an error, but we didn't
apply this logic when replaying a failpath, with strange results.

This is useful for seeing where failures cause us to run slowly
(ie. we continue for a long time before terminating).

We have to be consistent with the caller, so turn on 64 bit offsets if
available for both the caller and us.

As pointed out by Christian Thaeter, it has bitrotted.

Now valgrind children report failures, this one test fails.

This is the CCAN Way.  Plus, eliminates a compile warning here.

As per the SAMBA version.
