1e9a26c759 Catch up to changing interface of JacobianSystem class. 
While here, allow user to override policies for negating a vector and
zeroing the vector.  Moreover, the JacobianSystem no longer assumes
responsibility for solving the Jacobian system of linear equations, so
accept a linear solver parameter in solve().

321f84b4f6 Separate handling of NR vectors out to new class NewtonVectorCollection. 
The class is parametrised on policies for setting the size of
individual vectors, adding two vectors, and assembling local
contributions into the residual vector.

Provide default implementations of these policies, suitable for
base-vectors that implement (some of) the std::vector<T> interface.

d9aa8888ea Relinquish row/nnz control to linsys assembler. 
Pass the scalar number of rows and non-zeros into .setSize() along
with the number of degrees of freedom per cell.  This allows the
assembler to impose block structure in an optimal way for each
particular type of linear system.

d5010efdba Solvers need to be fully formed objects. Store references. 
For instance, an iterative linear solver is likely to need some kind
of stopping criterion and the implicit solver should not be tasked
with defining the criterion.

8769665658 DefaultNewtonVector: Allow outside access to the wrapped base vector. 
Should be used sparingly, but is needed, e.g., to solve systems of
linear equations.

bdbd90916b 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...

2c89db5f87 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.

abc87e170f Adapt to removal of 'const' in struct compr_quantities. 
The members cannot be 'const' in C lest the structure be impossible to
create using traditional C idioms (a sequence of malloc() calls).  If
the library is to be usable in a more general context, we cannot impose
C++ specific conveniences.
