xdiff: use unambiguous types in xdl_hash_record()

Browse Source 
Convert the function signature and body to use unambiguous types. char
is changed to uint8_t because this function processes bytes in memory.
unsigned long to uint64_t so that the hash output is consistent across
platforms. `flags` was changed from long to uint64_t to ensure the
high order bits are not dropped on platforms that treat long as 32
bits.
