f48950aa4d EQUATIONS: Completely rewrite this module. 
Now, module EQUATIONS provides a complet interface for equation systems,
including the definition of the number of equations/independent
variables, variable indices and names, conversion subroutines between
primitive and conservative variables, flux and characteristic speed
calculation, and maximum speed determination.

8dcc4d95b7 Remove PREC flag to set the computation precision. 
The code by default works only with double precision arithmetics.  Quad
precision arithmetics can be added as an option in the future.

92e67b2f36 Fix an MPI bug in new_time_step(). 
The maximum level was estimated from the list of data blocks.  If we
have many processors, sometimes all blocks could lay at level smaller
than maxlev, what can cause wrong dx_min estimation and desyncronization
between processors.

4669367697 Rewrite subroutine check_refinement_criterion(). 
These modifications slightly speed up the criterion calculation and
applies new default values of the parameters crefmin and crefmax, which
have been tuned in the blast problem.

39afde1328 Check the refinement criterion before storing it in the file. 
This step is required, since the mesh can be refined/derefined just
before the snapshot dump.  Since the refinement is checked before the
mesh update, it means that the freshly refined/derefined blocks have
undetermined array %c in their structure.

db606cfa1a Use primitive variables in the Riemann solvers. 
There is no need to convert conservative variables to primitive ones,
since they are already up to date, so pass primitive variables directly
to Riemann solvers in subroutine update_flux().
