PetscDefined: test whether a configuration macro is defined without #ifdef

This allows testing configuration macros from normal code, thus avoiding
unused variable warnings and allowing the compiler to check for syntax
errors throughout all alternatives. This uses C99-style variadic
macros with a second expansion to appease MSVC's non-conforming
implementation of variadic macros.

This trick was introduced by "comex" on Google+ in response to a
question posed by Linus Torvalds.
https://plus.google.com/+LinusTorvalds/posts/9gntjh57dXt

This technique (modulo MSVC support) was implemented in the Linux kernel by Paul Gortmaker:

- Now you have to call DMCopyDS() after labels have been established on the coarse DM
- Also, p4est setup has to have happen

PC: ASM, Block Jacobi: when viewing, note local solver on rank 0 is shown

The KSPView() call shows the (sub-)KSP on rank 0, which should have the same
type, PC, parameters, etc., but will not be the identical solver,
as the size of the local subdomains and the entries of the local
submatrices will be different. For instance, the output only shows
the local Mat for rank 0, which might confuse a user into thinking that
the subdomains are all of the same size when they are not. Similarly,
a PC like LU would show different factorization details on different
ranks, even though the solver settings are the same.

Make the viewer output more precise by noting explicitly that is
displaying information for the rank 0 subsolver.

Update test output with the new string.
