75b8511941 Fixed compiler warning about mixing code and variable declarations in 
bicgstab.c.

3882194573 Changes to bicgstab to resolve issue 760. Essentially when the residual is 
updated exactly inside of BiCGSTAB, then a divide by zero occurs.  Also, the
residual norm check was moved to occur immediately after the residual update.

e3181f26b1 Added 64 bit feature using HYPRE_Int (see tracker [issue489] for details). 
Changed MPI routines to hypre_MPI routines.
Added hypre_printf, etc. routines.
Added AUTOTEST tests to look for 'int' and 'MPI_' calls.
Added a new approach for the Fortran interface (not implemented everywhere yet).

9f26a7739a Changed 'cp -fpd' to 'cp -fpPR' for better portability. 
This should work on the Mac now in particular.

8ed12c2264 Added the release number to the names of hypre shared libraries (see [issue181]). 
Also removed the HYPRE_LSI library because it was nearly identical to HYPRE.

4f9d2e11de Changed the recompute_residual_p option to behave like "restared CG". 
This is more useful in practice than to keep the old search directions.

4502255f79 Added two new features to PCG: 
1) A new, residual-based stopping criteria ||r_old - r_new|| < rtol ||b|| which
   is activated with HYPRE_PCGSetResidualTol() and is designed to be used in
   high-accuracy computations with rtol <= 1e-16.

2) HYPRE_PCGSetRecomputeResidual(), which periodically recomputes the residual
   from scratch (r=b-Ax). This, again, can be useful in high-accuracy
   computations, but is potentially expensive and can lead to degraded
   convergence!

c52c6035dd Checking in a number of changes: 
1) Added the FlexGMRES and LGMRES solvers to the IJ, Struct and SStruct
interfaces.

2) Added the absolute tolerance interface functions (for all Krylov
solvers) to the Struct and SStruct interfaces (including fortran).

3) Added the absolute tolerance interface functions to the IJ fortran
interface.

4) Added the absolute tolerance check to the AMG Hybrid solver.

5) Updated some documentation information in the interface header files.

b52bf2037c If the user requests it, and CG seems to have converged, recompute the 
residual from scratch (as b-Ax) and use that to redo the convergence test.

d10dfd65c6 Fixed some bugs with the relative change test for GMRES. Also changed 
the functionality so that the check is done within the restart cycle.

Previous order was creating problems with the lobpcg_BLASLAPACKFunctions
structure. See issue25 for more details.
