SCHEMES: Fix adiabatic HLLD solver for MHD.
...
For one of the degenerate situations the state vector was not
calculated. This introduced numerical instabilities. This change fixes
it.

INTERPOLATIONS: Fix MLP limiting.
...
We should take half of the TVD limited derivatives in order to compare
properly with the high order interpolated derivative. Fix it.
Also, TVD limit both states if the high order interpolation of any of
them overshoot.

SOURCES: Fix calculation of η J² term.
...
In the sum of the J² we used Fortran subroutine sum() and the sum was
done along the 2nd index. However, the interpretation of this index is
uncertain when the first array rank is 1.
Therefore, instead of using subroutine sum(), the calculation is done
directly.
After this change there are no strange effects appearing on the
boundaries of the blocks.

INTERPOLATIONS: Implement Multi-dimensional Limiting Process.
...
This additional multi-dimensional limiting can be applied to any
reconstruction method. It is controlled by the parameter 'mlp_limiting'
by setting 'on' or 'off'.
The implementation is based on Gerlinger (2012).
