[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

Resolves flyspray 1265 and presumably 1249.

[Merge][CMake] -r7398 from branches/cmake: [BugFix] Fix endless recursion in dune_add_latex_document.

We now check whether the tex source exists. If not we check whether
the pdf is already in the source tree, otherwise we send an error.

[[Imported from SVN: r7383]]

Previously there still was a dependency to build the pdf which miserably failed as we don not distribute tex files.

[[Imported from SVN: r7382]]

The tarballs already contain the generated pdf files. No CMake 
will detect whether the pdf are contained in the source tree.
If that is the case they will not be generated and installed directly.

- 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

- Adapted dunecontrol and duneproject accordingly.
