Update typedefs.list to match what the buildfarm currently reports.

Update typedefs.list to match what the buildfarm currently reports.

The current list from the buildfarm includes quite a few typedef
names that it used to miss.  The reason is a bit obscure, but it
seems likely to have something to do with our recent increased
use of palloc_object and palloc_array.  In any case, this makes
the relevant struct declarations be much more nicely formatted,
so I'll take it.  Install the current list and re-run pgindent
to update affected code.

Syncing with the current list also removes some obsolete
typedef names and fixes some alphabetization errors.
