Change calling sequence of fortran solvers

[rjleveque]

Changes to the Riemann solvers agreed on in May but not yet implemented...

Aron and I just went through the Riemann solvers and are considering
the following changes...

For now stick with mx, etc. and use maux instead of num_aux.

Get rid of maxm in calling sequences: this is no longer needed since
the cell variable is the last index.

Reorder parameters to e.g:
subroutine rpn2(ixy,mx,meqn,mwaves,maux,mbc,ql,qr, &
auxl,auxr,wave,s,amdq,apdq)

Declare ql,qr,auxl,auxr as intent(in) (and convert dimension
statements to f90 more generally)

Change order of rpt2 parameters to
subroutine rpt2(ixy,imp,mx,meqn,mwaves,maux,mbc,ql,qr, &
aux1,aux2,aux3,imp,asdq,bmasdq,bpasdq)

to move imp up to position 2.

A couple related changes in 3d.

Change order of rpt2 parameters to
subroutine rpt2(ixy,imp,mx,meqn,mwaves,maux,mbc,ql,qr, &
aux1,aux2,aux3,imp,asdq,bmasdq,bpasdq)
to move imp up to position 2.

This has been done.

We still need to:

1. Remove maxm.
2. Use intent statements and F90 declarations
