PCMPI should pass block size to parallel matrix for the preconditioner to utilize

Additional properties of the matrix should also be sent out automatically such as symmetry

PCLMVM: do not use public API

PCLMVM is the default choice for tao bound-constrained solvers
If a user changes the type at runtime, the preconditioner is always reused

PCEISENSTAT: enable use within KSP solvers that use PCApplyTranspose()

Performs the same operation as PCApply(), assuming that Amat is symmetric

PCEISENSTAT: check errors produced in MatSOR()

PCEISENSTAT: fix to work with KSPPIPECGRR (needs to compute the norm of A)
