Yes, really ugly but Barry still cannot master awk

Change matrix factor database options that occur in KSP/PC to always use KSP/PC options prefix

Add MatSetOptionsPrefixFactor() and MatAppendOptionsPrefixFactor() to allow controlling the options prefix
used by factors created from this matrix

Change MatSetOptionsPrefix() to no longer affect the options prefix used by factors created from this matrix

As part of the above work the handling of the factor matrix options is now done in code in the factor matrix
not in the code that originates the factor matrix

Update examples output to the new approach where the factored matrix prefix is set from the KSP/PC

Much of this work was performed by Hong Zhang

-dm_bind_below tests now use last field of the -log_view data

This corrects an issue with the previous version of the tests, which
extracted field number 24 (intended to be "GPU Mflop/s"). In some
cases, there would be no space between columns of the -log_view output,
causing awk to extract the wrong value. By telling awk to extract the
last field, it will always use the "GPU %F" measurement, which should
always be zero if -dm_bind_below is working correctly.
