sundials: disable f77 properly
cleanup MatMatMult_MPIAIJ_MPIAIJ(): use Elist for options on experimental algorithms
rename MatMatMultSymbolic_MPIAIJ_MPIAIJ -> MatMatMultSymbolic_MPIAIJ_MPIAIJ_nonscalable (non-default)

moab: git download should depend on presence of 'autoreconf' - and use it to build configure
Merge branch 'jed/pcmg-residual-underscore' (early part) into maint

* 'jed/pcmg-residual-underscore' (early part):
  Fortran: PCMGResidual_Default needs to handle double-underscore
update nightly tests
rename MatMatMultSymbolic_MPIAIJ_MPIAIJ_Scalable -> MatMatMultSymbolic_MPIAIJ_MPIAIJ because this routine is default
