Add runtime checks for number of query parameters passed to libpq functions.
The maximum number of parameters supported by the FE/BE protocol is 65535,
as it's transmitted as a 16-bit unsigned integer. However, the nParams
arguments to libpq functions are all of type 'int'. We can't change the
signature of libpq functions, but a simple bounds check is in order to make
it more clear what's going wrong if you try to pass more than 65535
parameters.
Per complaint from Jim Vanns.
