[petsc4py] Support for Python monitors in KSP/SNES/TS

Hg-commit: e091e5b79133ed1b05de1a2a1bcf4c83c6fd2b2c

Make SNES more tolerant of not providing a vector to hold the residual.

It is now created internally in more circumstances.

more work on adding complete support for replacing DMMGSetSNES() with SNESSetDM() and removing DM. Now the coloring version of compute Jacobian works as does grid sequencing. Next proper support for PCMG?? computing the coarser matrices from the fine grid current solution is needed.

Add -snes_compare_explicit{,_draw,_contour} to compare various computed Jacobians.

This is similar functionality to -snes_type test, but includes drawing
and does not disrupt the solve. This is handy if the Jacobian only
becomes significantly different after the first iteration, or if there
are caching bugs.
