Simplify htools.hs personality selection

No need to do a boolean-based lookup, we can use the regular
association list lookup.

Change type of program options to 'IO [Options]'

Some options have defaults that depend on the environment, and we
could handle these in two ways:

- use a place-holder value (e.g. data X a = Default | Custom a) that
is later read from the environment
- move the options list to IO monad, where it can read the...

Fix compatibility with newer Haskell libraries

This small patch fixes compatibility with a few newer Haskell libraries:

- base 4.6, included with ghc 7.6, removed the deprecated 'catch'
function from Prelude, so our "import Prelude hiding (catch)" is now...

Define the actual arguments that are supported by programs

This defines the arguments supported and then modifies the
--help-completion output to include them too.

Rename Ganeti/HTools/Utils.hs to Ganeti/Utils.hs

This is, I believe, the last non-htools specific file that still lived
in the htools directory; it's already widely used in non-htools code,
so let's move it before we add more functionality to this module....

Remove generic options from individual programs

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,...

Switch to new-style exception handling

Currently, we're using Prelude.catch to handle I/O errors in
htools. This style of error handling has been deprecated for a while,
but it still used to work without warnings.

However, the GHC release 7.4 has started to emit deprecation warnings...

Split the list of program personalities into a module

… a mini-module, actually. This is only done for unit-testing, as we
don't want to duplicate the personalities list in the tests.

Parse options in htools.hs, not in each program

This patch moves the call to getArgs/parseOpts into htools.hs, as
opposed to the current situation where htools.hs only calls the main
file of each program, which in turn calls these two functions.

By doing it only once we remove some duplicate code and we also export...

htools: adjust imports for newer compilers

While testing with ghc 7.2, I saw that some imports we are using are
very old (from ghc 6.8 time), even though current libraries are using
different names.

We fix this and bump minimum documented version to ghc 6.12, as I...

htools: switch hspace to the generic binary

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...
