d9a43e8b32 Add subroutine update_corners() to module BOUNDARIES. 
This subroutine is called before the boundary update and assures that
the values stored in all cells of block are physical, even if they do
not influence the solution.

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().

63d1c8c0b1 Implement subroutines advance() and advance_rk2(). 
Subroutine advance() is a replacement for the subroutine evolve().  It
performs one step variable update by calling the selected integration
method.  So far only 2nd order Runge-Kutta is supported, which is
implemented in subroutine advance_rk2().

Subroutine advance_rk2() advances the conservative variables by one step
using the 2nd order Runge-Kutta method with the boundary update after
each substep.  This results in the reduced number of ghost zones, for
example 2 instead of 4, as in the previous version.

2e26d47362 Add two arrays of conserved variables to the block structure. 
In these two arrays we store temporary states during the Runge-Kutta
integration.  The new pointer %u in the block structure points to the
current array of the conservative variables.
