if an implementation of shared_ptr has been found in either std, tr1, or boost, then use that one.  If not fall back on our own

rename the method count() to use_count().  This is the naming of the standard shared-pointer implementation

principle of least surprise: executables should have the same name as the source file that contains main()

the class from SmartPointer to shared_ptr.  That way the implementation
is like the tr1 one.  The old file is deprecated.  The tr1 implementation
is not yet used even on platforms that have it, because I have to think
of a proper test first.

We'll need this for virtual shapefunctions.

This is meant as proposal for fs#597.

* Turn STRIP_CODE_COMMENTS on in Doxyfile.in.  Otherwise, doxygen seems to
  remove comments from \code...\endcode blocks.  This has the side effect that
  comments are no longer stripped from the source code doxygen presents via
  the web interface, which is probably a good thing in itself.

Thanks to the guys of statoilHydro for trying istl with
-D_GLIBCXX_DEBUG which gave a hint that somewhere was a bug.

Otherwise on some 64bit platforms we run into trouble.

Fixed parmetis check. Parmetis is only enanbled if the correct
CPPFLAGS are used (just like MPI).
