.cvsignore update...

I don't know that there's a consistent approach to .cvsignore files in
PostgreSQL's repo, but, there are some of these files scattered around,
but it's far from complete. The attached patch either updates (in a
few few cases) or adds .cvsignore files. The .cvsignore files in this
patch don't include .gdb_history, .emacs.desktop, or .DS_Store files,
but I figure those users are in the minority. This both greatly speeds
up updates (CVS is no longer being braindead and doing across the wire
binary compares for a file that the repo doesn't have or compares for
generated files) and reduces the output from 'cvs up' considerably,
which I find makes the output much easier to digest. Anon-cvs
administrators will also be thankful for this reduction of CPU and
network... if they're busy enough of a hub.

I'm of two minds about this. The first being to rip all .cvsignore
files out of the repo and let every developer administer their own
.cvsignore files. This would let developers taylor their .cvsignore
files to include .emacs.desktop, .gdb_history, etc, but comes at the
cost of a fair amount of duplication of effort. The flip side being,
there seems to be some president to keep .cvsignore files around but
appears as though the work just hasn't been done to keep things up to
date. If that's the case, here's the work.

Because there area large number of files in question, I've included
the appropriate cvs add [filenames] and cvs ci [filenames] commands so
that this can be added in one go (the file list for the cvs add is
different than the cvs ci).
