Rename typedef "string" to "VarString".

Since pgindent treats typedef names as global, the original coding of
b47b4dbf683f13e6 would have had rather nasty effects on the formatting
of other files in which "string" is used as a variable or field name.
Use a less generic name for this typedef, and rename some other
identifiers to match.

Peter Geoghegan, per gripe from me
