Merge origin/development into communication_v2

Realign communication_v2 with the latest development (10 commits, including the
GMRES refactor and the stopping-criterion change), keeping the communication_v2
work intact.

Conflict resolution:
- base/modules/Makefile (veryclean): keep communication_v2's '/bin/rm -f *.h'.
- linsolve/impl/psb_{c,d,s,z}rgmres.f90: keep development's variable
  declaration (itmax_, naux), consistent with development's refactored GMRES
  body which references itmax_.
