Pre-beta mechanical code beautification.

Run pgindent, pgperltidy, and reformat-dat-files.

The pgindent part of this is pretty small, consisting mainly of
fixing up self-inflicted formatting damage from patches that
hadn't bothered to add their new typedefs to typedefs.list.
In order to keep it from making anything worse, I manually added
a dozen or so typedefs that appeared in the existing typedefs.list
but not in the buildfarm's list.  Perhaps we should formalize that,
or better find a way to get those typedefs into the automatic list.

pgperltidy is as opinionated as always, and reformat-dat-files too.
