changed PCFactorSetMatSolverPackage() to NOT require the Mat before being called, now it just keeps a copy of the package name and uses it later

changed PCFactorSetMatSolverPackage() to NOT require the Mat before being called, now it just keeps a copy of the package name and uses it later
added PCFactorSetUpMatSolverPackage() actually calls MatGetFactor() so there now exists a factor matrix and PCFactorGetMatrix() can be called and then options set from the program.

added PCRedistributeGetKSP()

Hg-commit: 7979d255c25c706a54e3d24bfb09c9945e3d325f

Fortran bindings for PCRedundantGetKSP() need to include "petscksp.h", why is bfort not smart enough to pick up direct includes?

Hg-commit: d2b300ce8a853af044faf90a0161016264d4dfff

changed PCREDUNDANT to actually use the KSP in the object! Now -redundant_ksp_type gmres for example works

Added GASM example ex8g to testexamples_C.

Hg-commit: 44f4869c3a9d0ee3fcf89bcee9b9c5876d05c6e1

rank-straddling GASM is trickier than I had thought. ex8g seems to work now.
There is an inherent serialization of subdomain solves imposed by the current PCGASMCreateSubdomains2D algorithm.

rank-straddling GASM is trickier than I had thought. ex8g seems to work now.
There is an inherent serialization of subdomain solves imposed by the current PCGASMCreateSubdomains2D algorithm.
Subdomains should be globally reordered, to remove serialization. This can be done, but I haven't done it yet.
In general, the burden is on the user to provide a good subdomain ordering.
