This makes the naming consistent again.

Several members of `std::allocator` were already deprecated in C++17
and have now been removed in C++20. This patch uses the appropriate
members of `std::allocator_traits` instead.

This commit replaces all use cases of std::for_each(..., std::mem_fn(...))
by a much more readble plain range for. It does not replace other uses,
where this may be more controversial.

The former one was deprecated in C++11 and removed in C++17, causing
compilation failures on Clang 5 with libc++.

I already wanted to use those when implementing the UMFPack
integration into the overlapping schwarz, but our compiler
requirements were not sufficient at the time.

Since revision 8df1d996 overlappingschwarz
with UmfPack was broken due to renaming an internal variable accessed by a friend.
This patch fixes this by adding a new private method to access the internal matrix
of solver and uses that for the assembly.

now the preconditioner can be used in a Dune::Preconditioner context

This commit contains
- a wrapper for the C library UMFPack
- tests for both CMake and autotools to find UMFPack on the system
- a unit test for UMFPack
- a new MatrixType ColCompMatrix which is a base class for a column
  compressed matrix. SuperLUMatrix now inherits from this base class.
  This way, no code is duplicated for the very similar interface in
  UMFPack.
- the SuperLU-specific part of OverlappingSchwarz code is abstracted
  to work with either SuperLU or UMFPack

Previously this code was plain wrong. It actually made a copy
of the vector and tried to swap its entries with the original vector.
The argument to swap even was a const reference!
Now we use the correct trick: vector().swap(other).
