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.

This reverts commits 030a9cb8 and
ae082df0.

There are two problems:

- Makefile.am breakage, which is trivial to revert
- unittest breakage, which honestly I'm not sure how to fix and how
  serial consoles interact with the unpause helper

After the reset, the startup --paused still works but won't unpause
the instance automatically (if I understood the code correctly).

Furthermore, the code also fixes a style issue in hv_kvm.py (too long
line) introduced by the next commit after the above two.

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.

OK, my previous small fix was not good. There is another issue: haddoc
(the documentation generator) needs to pass the same compiler options
(i.e. in our case, -DNO_CURL) to ghc. But in case of no curl, then it
shouldn't scan at all the RAPI library, as that is not used in our
builds.

Clearly, this is not a nice thing. So this patch changes from
including/excluding RAPI conditionally (in two places, the
ExtLoader.hs module and in hscan.hs), to always include RAPI, and
moves the curl/no curl login to RAPI itself, where it belongs.

Together with passing --optghc to haddock, this makes the builds
consistent both with and without RAPI. I also undo the removal of RAPI
from QC.hs.
