This patch makes it possible to bypass installation of the whitespace hook by specifying

VCSETUP_FLAGS="DISABLEWHITESPACEHOOK=1"

in the user's options. If dunecontrol encounters that flag, it will not attempt to install
the hook in any module, uninstall the hook if it has already been installed and output a
warning telling the user that he'll have to take care of whitespace by himself.

[[Imported from SVN: r7471]]

This patch allows the user to specify a file with Git configuration options that
will be applied during the vcsetup phase, which might be used to set a custom identity
within the repository (e.g. an @dune-project.org email address) or to set up personal
aliases.

In order to enable this feature, put the line
VCSETUP_FLAGS="GIT_CONFIG_FILE=</path/to/your/config/file>"
into your options file. The configuration file itself is fed to the command
"git config" line-by-line, so you can normally set an option by simply having a
line like "config_key value" in the configuration file. Lines starting with # are
skipped and can be used for comments.

This patch hooks vcsetup into the standard "dunecontrol all" incantation
that most users are likely invoke after cloning a repository. By running
vcsetup that way, most Dune users will automatically have the whitespace hook
installed, which should greatly improve the usability of user-submitted patches.

[[Imported from SVN: r7468]]

This patch adds the new command "vcsetup" to dunecontrol. This command
is intended to perform various setup actions on a module that has been
checked out from a version control system.

For now, the command

- installs the whitespace hook bin/git-whitespace-hook as a Git pre-commit hook
  if all of the following conditions are met:
  - the current module is a Git repository
  - the dune.module file contains the line "Whitespace-Hook: Yes"
  - there is no existing pre-commit hook that would be overwritten
  The script detects older versions of the whitespace hook and updates them
  if necessary.

- applies Git configuration settings from the file .vcsetup/config.
  The contents of the file is simply fed to "git config" line by line. That
  way, Git configuration keys can be set by simply adding a line of the form
  "key value". Lines starting with "#" are filtered out and can thus be used
  for comments.

- runs all executable files in the directory .vcsetup/run.d
  This can be used for more elaborate setups. Note that these scripts are run
  if any of the following files/directories are found: .git .svn CVS stamp-vc

Make autotools the default build system. 

One can select CMake using the --use-cmake switch. This prepares
the merge to the trunk.

  after configure)
- Make CMake module installation path configurable
- Detect CMAKE_MODULE_PATH automatically
  + First call find_package(dune-common) to query its CMAKE_MODULE_PATH
  + Then setup the module path
  + After each find_package of dune module update the CMAK_MODULE_PATH
  + each module exports ist own <package-name>_MODULE_PATH in the
  + package configuration files
- Adapted dunecontrol and duneproject accordingly.

Note: I looked through the patch and asserted that the resume feature is still
working (I always overwrite the resume file anyway). In case dunecontrol stops
working for someone, please simply revert this patch (if possible) and add a
comment to FS#958).
