I've addressed all of the points above (except splitting the base
patch up) and rebased on master. I didn't squash before generating the
patches so it may be easier to read the progress here, or annoying
that there are so many attachments.

This patchset hits all of Andres' points with the exception of the
reshuffling of functions like AuxiliaryProcessMain, but it does get
rid of a lot of direct argv string comparison. I'll reorganize a bit
when I re-write the patchset and will likely move
AuxiliaryProcessMain, along with the Backend subprocess functions but
just wanted to get this up here in the meantime.

There is quite a lot to be gained from this patchset in the form of
re-organization and removal of redundant code-paths/globals. I see
this as a good first step and am willing to continue to push it
forward with any new suggestions.
