Added functionality to selectively filter PetscInfo() output based on calling class to
mimic some OS system logs. New functionality includes:
- Filter for a set of classes
- Filter out a set of classes
- Filter for MPI/PETSC_COMM_SELF
- Filter for anything not on MPI/PETSC_COMM_SELF
- Writing PetscInfo() output to new file
- Appending output to existing PetscInfo() file
- Any combination of the above
Credit to Vaclav Hapla for raising the initial issue, helping design the eventual API, and
substantially assisting in debugging.

1) Separate out local communication from remote communication
2) Directly pass root/leafdata to MPI when suitable

mpich: update opensolaris builds of PETSc from using mpich-3.3a2 to mpich-3.3.1
The MPICH 3.3.1 HWLOC component with Solaris compilers and optimization -O hangs while calling MPI.
The fix suggested is to set HWLOC_COMPONENTS="-x86" in the environment
This is handled in PETSc by
1) setting the HWLOC_COMPONENTS="-x86" in configure before testing the MPI to prevent hangs during configure
1a) having configure print a warning that setting this environmental variable may be needed to prevent hangs in
running code
2) having PetscInitialize() set HWLOC_COMPONENTS="-x86" so the user does not have to, which handles most cases
except those where the user directly calls MPI_Init() and for that we have the warning at configure time
(can't have the warning at run time because the user calls MPI_Init() before they get to PETSc code.

Various improvements for GPUs (mostly for performance and CUDA)
1) Add VecPinToCPU() for CUDA vector and matrices
2) Move initialization of cuBLAS to PetscInitialize() since it takes 1/2 second and distorts timing with -log_view
3) Add logging for DMCreateMatrix (for large meshes this is very large)
4) Add VecGet/RestoreArrayWrite() to prevent unneeded copies from GPU (only implemented so far for CUDA);
added a small number of usages in the source so that snes tutorials ex19 does not do unneeded communication from the GPU
5) Automatically convert MAIJ matrices to AIJ for CUDA since they are not yet supported natively in PETSc's CUDA matrix implementation
6) Pinned objects should still use the CUDA/ViennaCL versions of Destroy to clean up the GPU stuff
