#2320: Rename RecordPuns extension to NamedFieldPuns

------------------------+---------------------------------------------------
The `NamedFieldPuns` has been around for ages. It's in the original Cabal
design spec in the extension list. It was implemented in nhc98 for yonks
(with the flag `-puns`). In older ghc it was enables with `-frecord-puns`.
In ghc-6.8 we split up the `-fglasgow-exts` flag into lots of separate
named extensions. We added an extension `RecordPuns` for the thing that
`-frecord-puns` had enabled previously not realising that there was
already an older name for the same thing, namely `NamedFieldPuns`.
So I propose that ghc moves to using the standard extension
`NamedFieldPuns` and keeps `RecordPuns` as a deprecated alias for
`NamedFieldPuns`. Cabal can fix things up so that for ghc-6.8 it maps the
`NamedFieldPuns` extension to `-frecord-puns` or `-XRecordPuns`.
The moral of the story here is that all the extensions in
Language.Haskell.Extensions should be well documented in that module. For
one thing that'd serve as a useful reference for users, but also for
compiler hackers to pick consistent names for the same concepts between
implementations.
