Subject: [PATCH] Fix function declaration mismatch warning with gcc-13/14:

beam/erl_nif.c:1476:8: warning: conflicting types for 'enif_binary_to_term' due to enum/integer mismatch; have 'size_t(ErlNifEnv *, const unsigned char *, size_t,  ERL_NIF_TERM *, ErlNifBinaryToTerm)' {aka 'long unsigned int(struct enif_environment_t *, const unsigned char *, long unsigned int,  long unsigned int *, ErlNifBinaryToTerm)'} [-Wenum-int-mismatch]

0 is a valid parameter but is not in the enum, so the extern
declaration is the correct one. Changed the function definition,
documentation, and a test case to match.
