Add PetscProccessManagementView() and -process_view to use hwloc to display location of PETSc MPI processes on cores
This is to allow users and developers to know if the correct binding and mapping of processes to cores
on multicore systems is done as expected. Without this benchmarking to develop optimized code is not possible

Allow -process_view to be used with streams, determined optimal binding for streams on Intel 4 numa thing system

Ignore -malloc-hbw option if malloc is already set

When this option takes effect and PETSc is configured with memkind, HBW allocator is used for the whole running period.
This suffices for normal us

Ignore -malloc-hbw option if malloc is already set

When this option takes effect and PETSc is configured with memkind, HBW allocator is used for the whole running period.
This suffices for normal users. For some use cases where one wants to control HBW memory explicitly,
(e.g. some checkpoint strategy needs to switch between MCDRAM and DRAM on KNL) do not use this option.
