Minor cleanup of function declarations for BRIN.

Get rid of PG_FUNCTION_INFO_V1() macros, which are quite inappropriate
for built-in functions (possibly leftovers from testing as a loadable
module?).  Also, fix gratuitous inconsistency between SQL-level and
C-level names of the minmax support functions.
