Change the hash_object_file() function to take an "enum
object_type".
Almost all of its callers were passing either
"{commit,tree,blob,tag}_type", or the result of a call to
type_name(). Let's instead benefit from type checking and use the enum
directly.
"Almost" because one caller here will now pass OBJ_BAD. The previous
"NULL" value was not used, as "check_object_signature()" will never
use its "type" argument when given a NULL "map" argument, which that
caller in "parse_object()" also does. We'll deal with it in a
subsequent commit, but for now it'll pass an "OBJ_BAD" placeholder.
