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

bin/git-whitespace-hook is a Git pre-commit hook that enforces our
whitespace policy for local commits. By installing this hook in a
local Git repository, users can make sure that there won't be any
nasty surprises when trying to merge their commits to the central
repository later on.

Moved add_dune_<package>_flags functions out of the
Find<Package>.cmake modules, as they were missing with set
CMAKE_DISABLE_<Package>=TRUE.

Now they are in speparte modules Add<Package>Flags and thus can be
used as exspected with disabled packages.

  The previously used check_symbol_exists is meant for checking
  symbols defined in headers.

Original message was:
[Bugfix] Prevent definition of HAVE_BOOST without value due to race conditions in some autoconf versions.

For some autoconf versions there was a race condition between ax_boost_base.m4 and dune_boost_base.m4 resulting in HAVE_BOOST being defined with no value (instead of ENABLE_BOOST). For others there were even two definitions of it (one with and one without value). 

This patch renames the symbol being defined in dune_boost_base.m4 to HAVE_DUNE_BOOST and defines a value for it if boost is found.

Please change your code such the preprocessor directives checking for boost from
#if HAVE_BOOST
to
#if HAVE_DUNE_BOOST

One would think that this is an easy task, but it turns
out that subversion has many problems when merging back and forth
with deleted or added files. This needed a lot more manual
polishing than exspected.
