Due to the fact how the automake system works it doesn't rebuild already
prebuild files in distcheck. This lead to a bug, where a rebuild of the
documentation was failing because we missed the fact that the files were
missing from the archive.

By adding distrebuildcheck we workaround that issue by running a
maintainer-clean which also removes prebuild files.

This patch works around an issue in our build system. Since we don't
use cabal or 'ghc -M', we don't track actual dependencies in our
Makefile; this in turn means that editing a file that only is used in
the main 'htools' binary will keep triggering 'ghc --make' for the
hconfd binary; and this actually takes a bit of time to look at all
the dependencies.

So to work around this, we add a touch after each ghc --make, such
that we trigger the unneeded build at most once.

Due to the way $(MAKE) behaves (it forces execution of the commands
that contain it), use of $(MAKE) in a command line together with
side-effects commands will break stuff. It's better to keep it either
on a separate line, or if not possible, move said commands to a
separate make target.

Currently, the lint target does a sequential: pep8, pylint, pylint on
the QA sources. hlint is run only when explicitly requested.

This patch reorganises the lint target by:

- splitting the current lint target into separate pylint (slow),
  pylint-qa (fast), pep8 (fast) targets
- making lint itself depend on the above plus hlint
- both pep8 and hlint are optional, based on whether the said binaries
  were detected at configure time

make -j is slightly faster after this patch (1m18s → 1m7s).

This is the 2.5 version of the "fix build failures":

- make man/%.gen runs RUN_IN_TEMPDIR, so let's depend on it, since
  that target has the proper dependencies (create needed dirs)
- man/%.gen depends on a number of built sources, but the dependency

The vgreduce command has changed behaviour from when we initially
wrote the code (2.02.02 versus 2.02.66, 4 years delta):

- if there are LVs which will be impacted, it requires --force
- otherwise refuses to proceed, but it still returns exit code 0

We handle this by looking to see if it returns "Wrote out consistent
volume group" (behaviour unchanged), or if it complains about
"--force"; in the case it didn't complete, we retry the operation.

We improve a bit the checking of "vgs", as it uses to fail silently
and we didn't detect it.

New tests for this function should test, I believe, all the expected
variations; at the least we now have data files with the expected
output.

While testing some other stuff, I realised that the gnt-* commands
could be broken (as in, the script fails with syntax errors), but make
check doesn't detect it. Since we have shelltest, we can now add
trivial tests for this case.

One downside is that starting the scripts seems to be much slower
than the htools binaries, so we can't add as many tests.

The other downside is that shelltest is now required for all
development work, but I think this is a small disadvantage compared to
the increased testing possibilities.

This patch changes configure.ac Makefile.am so that the user can pass:

- --disable-confd (or --enable-confd=no) to disable it completely
- --enable-confd=yes or --enable-confd=python to select the
  traditional implementation (this is the default setting)
- --enable-confd=haskell to select hconfd

The only "not nice" thing is that I've chosen to keep the
hconfd.hs/hconfd name, and we rename it after install via an
install-exec-hook. The other choice is possible too (to rename the
source file/binary).

One additional note is that if we select haskell, the _rule_ for
creating daemons/ganeti-confd dissapears; whereas if we select python,
the rule for htools/hconfd still exists (one can build it explicitly),
it just is not installed. This is due to the different way in which
the rules are declared.

This is more of a RFC… Basically most of the shell-based tests are
converted from exec+grep to shelltestrunner.

Things are not all fine and nice though:

- we have dependencies between tests, as some generate some data files
  needed later; this is not nice, and we depend on serial execution in
  testrunner
- we can still fail with no so nice messages in the offline-test
  script (when we generate most of the data)

But overall, I think the tests are much nicer to
define/read/debug:

- each test is standalone, with the only dependency being an optional
  input data file; this is much better than a single monolithic shell
  script
- in case of failures, the failure is clearly shown by shell test,
  both for exit code and stdout/stderr
- shelltest can run in --debug mode, where the exact details are shown
  much better than the alternative of "set -x" for the shell script

Comments welcome!
