[PATCH v2 03/10] object.c: make type_from_string() return "enum object_type"

[Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx>]

Change the type_from_string*() functions to return an "enum
object_type", but don't refactor their callers to check for "==
OBJ_BAD" instead of "< 0".

Refactoring the check of the return value to check == OBJ_BAD would
now be equivalent to "ret < 0", but the consensus on an earlier
version of this patch was to not do that, and to instead use -1
consistently as a return value. It just so happens that OBJ_BAD == -1,
but let's not put a hard reliance on that.
