Mark Andrews 25ba866b62 Make calling generic rdata methods consistent 
add matching macros to pass arguments from called methods
to generic methods.  This will reduce the amount of work
required when extending methods.

Also cleanup unnecessary UNUSED declarations.

Ondřej Surý 8a01f18958 lib/dns/rdata/*/*.c: Silence false positive nullPointerRedundantCheck warning from Cppcheck 
Cppcheck gets confused by:

void bar(void *arg) {
    foo *data = arg;
    REQUIRE(source != NULL);
    REQUIRE(data->member != NULL);
}

and for consistency the DbC check needs to be changed to

void bar(void *arg) {
    foo *data = arg;
    REQUIRE(data != NULL);
    REQUIRE(data->member != NULL);
}

Tony FinchandMark Andrews 660c9af77b cleanup: use dns_secalg_t and dns_dsdigest_t where appropriate 
Use them in structs for various rdata types where they are missing.
This doesn't change the structs since we are replacing explicit
uint8_t field types with aliases for uint8_t.

Use dns_dsdigest_t in library function arguments.
