This commit adds the core infrastructure of the monitoring daemon,
and integrates it in the build and test systems.

The actual functionality of the monitoring daemon is still completely
missing.

Per offline discussions, this is the first patch of the
renames. Tested with "make distcheck", seems to work fine.

The only change outside of the renaming is a bit of simplification in
the .gitignore rules; otherwise, simply s/htools/src/.

This mirrors the code in the Python code base, and is required for
clean error reporting during startup.

This patch implements the basic infrastructure; the confd daemon is
not yet modified to take advantage of this, just the types are
adjusted.

Also, the pipe-based error reporting will go in a future patch, once
we can actually use that for reporting.

Currently, we test and require that each individual program (hbal,
etc.) defines/supports the generic options (currently --help and
--version). Even with the test, this is not optimal, since it requires
changes in many places whenever we modify the list of generic options,
hence we move these out of the individual programs and into the
generic CLI handling code.

Instead of hardcoded IPv4 INADDR_ANY, this patch changes hconfd to use
either the any network for the configured cluster address family
(ipv4/ipv6), or whatever the user passes in via the --bind option.

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.
