This is not perfect, as for many of the parameters we don't have good
Arbitrary instances, but is better than nothing.

While adding yet another JSON serialisation test, I realised that this
can be trivially abstracted; hence this patch, replacing both simple
versions (readJSON . showJSON == id) and the standard version (with
different error messages) across the tests with a single function
call.

Since the DiskLogicalId type is manually serialised/deserialised (see
Objects.hs, `encodeDLid' and `decodeDLId'), let's add a test that
checks that these are idempotent when combined.

Since we're at it, let's add the same test for Node serialisation,
which already has an Arbitrary instance.

This adds test properties for the various laws that the instances of
Result should follow; I could not find (offline) laws about `mappend',
but otherwise I implemented all laws that I could find.

Note that we have to silence hlint warnings for the things we want to
test, as otherwise hlint is all "this is already true based on the
functor law, why 'fmap id' and not just 'id'?".

The names were not in a proper hierarchy, leading to inconsistencies
about what they were actually tested.

We change this by reproducing in the test names the relative hierarchy
within the Ganeti directory, leading to nicer test suite names (in
test-framework output).

Since we now have separate namespaces due to the multi-file split, we
don't need to keep the name of the module in the property names, as we
don't have so many potential conflicts anymore.

We remove the group prefix handling from TestHelper and simply do a
sed over all the test files, removing it from the function names.

In order to have correct code coverage results, we must somehow import
all production modules into the test runner. Until now, this was done
manually (when we didn't forget) in QC.hs.

To improve the situation, we remove QC.hs and replace it with an
auto-generated file which imports all modules. This reduces the
maintenance burden and ensures we'll always have correct coverage.

This makes QC.hs obsolete, but we will remove it in a later patch,
once we automatically build a file with all the imports (to ensure
correct coverage results).

These two files are not htools-specific, so let's move them out of the

Except for Ganeti.HTools.JSON, which needs rename, we split all the
other test suites into separate files.

We have to add another common test helper, due to import dependencies
(sigh), but otherwise this split is pretty straightforward.

This is the first file split out from QC.hs - an easy one, since it
has just one test.

The patch changes the way we build hpc excludes, since now we'll have
many modules that need to be excluded, and hpc doesn't seem to be able
to do wildcards (it can do packages, but all our code is
not-package-based).

Further splitting will be done in bigger batches.

This is the first commit of a series that will attempt to cleanup the
test code organisation, which evolved somewhat organically from the
initial pure htools functionality.

The proposed organisation of the tree will be as follows:

- htools (or maybe renamed to haskell or hs): only production code
- htest: top-level test directory, containing test.hs, static helper
  scripts, etc.
- htest/Ganeti/*.hs: modules implementing the actual test properties
  and test cases for the correspondingly-named production code modules
- htest/data: containing test data files for the test cases

This particular patch moves all the test code (test.hs, hpc-htools.hs
symlink) and helper scripts (offline-test.sh, etc.) from htools/ to
htest/, while updating the files themselves (if they had paths
mentioning htools/), .gitignore and the Makefile.

The only special mention is that in Makefile, we used to have a BINARY
shell variable in binary build rule; that was computed via stripping
`htools/' prefix; I've cleaned that and replaced with $(notdir $@);
even though it's duplicated a few times, it leads to more readable
make output (and easier to copy-paste).
