Commit c964d962 changed the way we create directories, by two things:

- unifying all dependencies and ad-hoc directory creation into a
  single target (all_dirfiles)
- changing how directories are created from a stamp file to .dir files
  in each directory

The first item is a very good one, but the second item is debatable:
there's no per-se advantage of .dir files versus a single one,
top-level, since both the .dir file and stamp-directories creation are
depending on Makefile, which is the only one which can introduce new
directories.

On the other hand, moving back from .dir files to stamp-directories
has an advantage: "make -d | wc -l" does from ~8.7K lines to ~5.3K
lines, because we eliminate the many .dir files and their multiple
implicit and explicit dependencies (the %/.dir files fall under
multiple patterns).

This is a stupid/trivial patch. I didn't realise when adding
htools-hpc that this will "break" tab completion on htools; as in, I
will have to add / manually always when completing files on the
command line.

So to fix my laziness, let's rename htools-hpc to hpc-htools,
eliminating this completion conflict.

Currently, most htools code depends on Constants.hs which is generated
from constants.py and also depends on _autoconf.py. Also, _autoconf.py
depends on vcs-version, which all together means that when 'make
regen-vcs-version' is run, for example by ./devel/upload, most of the
Haskell code needs recompilation.

Since htools already has its 'optimised' vcs-version (and doesn't use
the _autoconf.VCS_VERSION constants), we can optimise this as follows:

- _autoconf.py doesn't contain the VCS_VERSION anymore, and that is
  instead moved to _vcsversion.py
- constants.py depends on and imports this new module
- _autoconf.py doesn't get regenerated at vcs-version changes, but
  only at re-running configure/changing Makefile time

The end result is that only htools/Ganeti/HTools/Version.hs is
recompiled now, which is a significant speedup (usually < 1 second
versus 10 seconds previously).

This is the last patch of the binaries conversion.

As information, we now have a single binary that is approx. 5.4MiB in
size, compared to 4 binaries that were approx. 5.1-5.2MiB in size;
this will result in a smaller package and install size, and the single
compilation phase should also help.

With the merge of the repositories, we can now auto-generate the code
for Haskell constants from the Python code.

Currently this only handles the basic types (strings and
integers). Handling containers such as lists and dictionaries is only
possible if we would use a parser such that we recognise the element
names. We could extend the convert-constants script if that becomes
necessary, right now I'm looking at just the simple constants such as
Iallocator modes, instance states, etc.

Some directories don't exist in the repository, but are required at build time
(e.g. doc/html). Until now some were created explicitly, some through the
target “stamp-directories” and other target simply relied on a previous target
to create the directory.

This patch tries to clean this up by getting rid of “stamp-directories” and
instead use rules to recreate any missing directory. As described in a comment
in the code, a file inside each directory is necessary, named “.dir”.

Order-only dependencies are used for directory creation to avoid rebuilding
where only the “.dir” file is missing (see “info make”, section “4.3 Types of
Prerequisites”).

The target for building the documentation is also changed to use “…/index.html”
instead of a hidden file. Some style changes are also made.
