afdb88678f Fix remaining bugs for incompressible flows driven by sources. 
In particular:

  - Zero sufficient portion of the ->mat_row to hold all connections
    of a cell in addition to the accumulation term.

  - Don't write the residual into the accumulation term of the
    Jacobian matrix row.

dd042b75a8 Make first attempt at implementing the residual/Jacobian formulation. 
This is a step in the direction of having a true IMPES pressure solver
and to remove the 'experimental_jacobian' option in dune-porsol.

94fc6de78a Rework compressibility representation. 
Switch to storing a complete fluid-matrix derivative in the
compr_quantities rather than the total compressibility.  Maintain the
"volume discrepancy" field.  Also, add traditional memory management
functions.

c3036166a9 Factor pressure (increment) assignment out of _press_flux(). 
The linear solution h->x is the pressure increment, not the actual
pressure value, so we cannot compute fluxes based on h->x alone.

d085ddb314 Use portable array initialisation. 
Memset() and calloc() define arrays of bytes, not general objects.  This
is a lesson learned many times over by generations of C programmers...

70a9e8a7a8 Add companion output utilities based on already opened streams. 
Functions csrmatrix_write_stream() and vector_write_stream() subsume
the output responsibilities of csrmatrix_write() and vector_write(),
respectively, but do not deal with opening or closing streams.  This
allows, e.g., a call such as

    csrmatrix_write_stream(A, stderr);

for debugging purposes.

Re-implement csrmatrix_write() and vector_write() in terms of
csrmatrix_write_stream() and vector_write_stream(), respectively.

4313d35883 Increase readability of create_c2c(). 
Introduce two intermediate variables, c1, and c2, to hold cell numbers
during the building of the cell<->cell neighbourhood.  This reduces
the statement complexity--both for the human reader and the compiler...
