Remove allocator template parameter from the classes
`base_array_unmanaged`, `compressed_base_array_unmanaged`,
`block_vector_unmanaged`, `compressed_block_vector_unmanaged`, and
`CompressedBlockVectorWindow`.
All of these classes do not manage memory on their own.
The provided allocator was only used to deduce `size_type`.
The latter is now provided as template parameter explicitely.

Notice that this (seemigly breaking) change is safe, because
all these classes are clearly marked as implementation details
that should not be used outside of dune-istl.

And fix all spelling errors that codespell currently finds.

See https://reuse.software/ for a description.

These classes are internal to ISTL and used nowhere in ISTL.

Note: `base_array_unmanaged` is used internally by `BlockVector`, `Matrix`,
and `VariableBlockVector` and is thus not removed.

There are various classes in dune-istl that are effectively implementation
classes internal to dune-istl. A few of them are base_array_unmanaged,
base_array_window, compressed_base_array_unmanaged,block_vector_unmanaged,
BlockVectorWindow, compressed_block_vector_unmanaged, CompressedBlockVectorWindow

See #22 for a brief
discussion.

This patch moves the classes into the namespace 'Imp'.  That way it is
clear that they are internal.

All code outside of dune-istl using those classes will break, but does
such code really exist?

By using the doxygen \internal command.

These constructors and assignments from base class are
all using a downcast which may result in undefined behaviour.
Since this is potentially dangerous and not used anywhere
in the core modules, this patch removes those methods.

Required by the RandomAccessIteratorFacade

On request of Markus Blatt.  Supposedly there have been problems with and/or on
older compilers.

This fixes FS 1292, but with my own slightly different patch.

Memory was allocated with allocator.allocate(n) and always freed with
allocator.allocate(1). This might have resulted in memory leaks that
are not noticed by valgrind.
