* Libraries are in .../lib, not .../libs.
* When using AC_CHECK_LIB, the -L option has to be put into LDFLAGS
  temporarily.  Use DUNE_CHECK_LIB_EXT, which does that automatically.
* Clear the output variables if GMP was not found.
* Put result into ALL_PKG_* instead of DUNE_PKG_*

LOCAL_LIBS is meant to do.  Also remove the bad example of passing
preprocessor flags in CXXFLAGS from duneproject.

libs to the ALL_PKG_* family of variables and DUNE_ADD_MODULE_DEPS to add
flags and libs to the DUNE_* family of variables and the modules variables.
Use those macros in DUNE_CHECK_MODULES.

Rewrite the DUNE_CHECK_LIB_EXT macro:

 * Essentially copy and adapt the definition of AC_CHECK_LIB.  This should
   make sure the two macros behave the same even in corner cases (except for
   the added functionality, of course).

 * Properly document what exactly is allowed in the arguments.

Parse arguments to DUNE_CHECK_LIBS_EXT properly in parmetis.  This avoids
expansions like 'LDFLAGS="$LDFLAGS -L"$PARMETISLIBPATH""'.

std::tr1::array, but only by std::array. The reason is to avoid the
alignment bug is gcc-4.[012]

This allows Dune::FieldVector to inherit from Dune::array.

- autoconf documentation states that ifelse is remapped to m4_if
- the library check is AC_CHECK_LIB

I hope this is what was intended

@Christian: Could you please verify this?
