Replace CURLOPT_POSTFIELDSIZE_LARGE with CURLOPT_POSTFIELDSIZE

Also adds a more robust interface for setopt that does
type checking based on the options used. This fixes one
bug where a F32 was passed and interpreted as long.
In many cases a U32 or S32 was passed as long, which
would fail (only) on a 64bit non-windows big endian machine.
