The config.h entry for ENABLE_UMFPACK should be in the same
module as the test for UMFPack, to avoid future conflicts with
multiple modules running the test for umfpack.

If not found, our own fallback implementation will be used.

[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.

infrastructure to use the module with cmake.

Currently, only an installed dune-common can be used, as the others
lack the cmake confguration files. One has to provide the
CMAKE_MODULE_PATH pointing to the directory where
e.g. DuneMacros.cmake is installed (PREFIX/share/cmake/modules) and 
DuneCommon_DIR pointing to PREFIXlib/cmake.

The ${CMAKE_BINARY_DIR}/config.h.cmake of the project is created such
that it includes section from modules that it depends on as well as
the ${CMAKE_SOURCE_DIR}/config.h.cmake. This prevents user from
creating a full file by hand.

Renamed package configuration files according to the style of the 
other modules.

Do not use cmakedefine01, as DUNE relies on the fact that there is no
define if a feature is not there.
Use a similar order for the defines in config.h.cmake for better
comparsin with e.g. meld.
