PCGAMG: change default nsmooths, reuse_interpolation, threshold
-pc_gamg_agg_nsmooths 1 (was 0)
Although unsmoothed aggregation is more robust, smoothed is faster for
the problems that AMG is most frequently used for.
-pc_gamg_reuse_interpolation FALSE (was TRUE)
Lagging interpolation by default causes GAMG to spuriously fail for
many nonlinear problems and transient problems with moving coefficient
structure, and with variable time steps.
-pc_gamg_threshold 0.0 (was .001)
ML does not use thresholding by default, so this change makes GAMG
algorithmically more similar. Increasing the threshold causes slower
coarsening, which increases grid complexity. It is critical for
anisotropic problems.

PetscStackCallBLAS: new macro instead of PetscStackCall (skip CHKMEMQ)
When CHKMEMQ occurs on every call to BLAS or Lapack, we sometimes see
unacceptable performance degradation (orders of magnitude).
PetscStackCallBLAS is currently identical to PetscStackCall except for
skipping CHKMEMQ, but such checking could be made optional in the
future.

Avoid stomping on user subtype preference in PCSetFromOptions_GAMG.
Subtype function pointers are now cleared by PCGAMGSetType to avoid
lingering from the last type in cases where not all pointers get set.
Also store the type name to help with debugging and diagnostic output.
