When compiling with the parallel-3.x library, we get a deprecation
warning, which makes understanding any other error messages
harder. This patch adds a compatibility module that will hold such
code for transitioning libraries.

Just saw this while testing the migration to QuickCheck v2: while
configure.ac detects that QuickCheck-2.x is not available, the test in
Makefile.am was against WANT_HTOOLS (overall htools compilation), not
on a more-specific WANT_HTOOLSTESTS.

Since current distros don't package anymore QuickCheck 1.x, let's move
to 2.x.

This requires also a few changes to the code:

- Test.QuickCheck.Batch doesn't exist anymore, so we need to write some
  scaffolding code to replace it
- the way test sizes are generated has changed, and we need to restrict
  (in some tests) the cluster size, as our code is not yet ready for
  hundreds of thousands of nodes in a cluster and we run out of stack
  (which could be a bug somewhere by itself, needs investigation)
- at least with GHC 7, floating point errors make a perfect cluster
  score even bigger, so we need to bump up the max. rounding error
  allowed

RAPI needs the curl module, which is a binding to the libcurl C
library. This is more complex (can be compiled either against gnutls
or openssl, etc.) and it's not of much help when the tools are used on
the cluster itself, we disable it by default.

This patch adds an enable/disable option for htools (--enable-htools),
and associated tests for determining whether GHC (the compiler we use
for htools) and required libraries are present.

The method to do so is not very nice; usually, Haskell programs are
configured and compiled using cabal (http://www.haskell.org/cabal/

, a
tool similar to Python's setuptools)), but that doesn't suit itself to
nice integration with autoconf/automake, so we test for the modules
presence manually.

In the end, we set a few variables:

- GHC: the path to the ghc compiler
- HTOOLS_MODULES: command line option for ghc to select the wanted
  'parallel' module
- HTOOLS_NOCURL: set to -DNO_CURL if we don't want to enable curl (and
  thus RAPI) support in htools
- HTOOLS: set to 'yes' if we should compile/install the htools
  programs
- HTOOLS_APIDOC: set to yes if we should build/install the htools
  API documentation
- WANT_HTOOLS, WANT_HTOOLSAPIDOC: two automake conditionals for later
  use in Makefile.am

This patch introduces core file storage support, consisting of the following:

A configure-time switch for enabling/disabling shared file storage
support and controlling the shared file storage location:
--with-shared-file-storage-dir=.  Shared file storage configuration is then
available as _autoconf.ENABLE_SHARED_FILE_STORAGE and
_autoconf.SHARED_FILE_STORAGE_DIR and there is a cluster-wide ssconf
key named "shared_file_storage_dir" for changing the file location.

A new disk template named "sharedfile" (DT_SHARED_FILE), using
ganeti.bdev.FileStorage.

Auxiliary functions in lib/config.py to handle shared file storage.

As per issue 124, some Xen versions (or packaging) don't deal nicely
with the colon being part of a disk name. Therefore we add a
configure-time option for customising this.

Note: setting the separator to interesting values like / is not
handled by the code. This being a configure-time option (e.g. to be
set by distribution packagers), we assume the person building the code
knows what they are doing.
