This way, they can be used by frontend and backend code. We already
supported that, but doing it this way allows us to mix true frontend
files with backend files compiled in frontend environment.

duplicative -DFRONTEND flags from many Makefiles. We still need Makefile
control of the symbol in a few places that compile frontend-or-backend

Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything

picked up the right entries ...
are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.
