pgsql: Consistently use named parameters in timezone code.

Consistently use named parameters in timezone code.

Make our copy of the IANA timezone library use named parameters in
function declarations. Also make sure that parameter names from each
function's declaration match corresponding definition parameter names.

This makes the timezone code follow Postgres coding standards. The
value of having a consistent standard everywhere seems to outweigh the
cost of keeping the function declarations in sync with future IANA
releases.
