hash.h: move object_id definition from cache.h
Our hashmap.h helpfully defines a sha1hash() function. But it cannot
define a similar oidhash() without including all of cache.h, which
itself wants to include hashmap.h! Let's break this circular dependency
by moving the definition to hash.h, along with the remaining RAWSZ
macros, etc. That will put them with the existing git_hash_algo
definition.
One alternative would be to move oidhash() into cache.h, but it's
already quite bloated. We're better off moving things out than in.

khash: rename oid helper functions
For use in object_id hash tables, we have oid_hash() and oid_equal().
But these are confusingly similar to the existing oideq() and the
oidhash() we plan to add to replace sha1hash().
The big difference from those functions is that rather than accepting a
const pointer to the "struct object_id", we take the arguments by value
(which is a khash internal convention). So let's make that obvious by
calling them oidhash_by_value() and oideq_by_value().
Those names are fairly horrendous to type, but we rarely need to do so;
they are passed to the khash implementation macro and then only used
internally. Callers get to use the nice kh_put_oid_map(), etc.

khash: rename kh_oid_t to kh_oid_set
khash lets us define a hash as either a map or a set (i.e., with no
"value" type). For the oid maps we define, "oid" is the set and
"oid_map" is the map. As the bug in the previous commit shows, it's easy
to pick the wrong one.
So let's make the names more distinct: "oid_set" and "oid_map".
An alternative naming scheme would be to actually name the type after
the key/value types. So e.g., "oid" _would_ be the set, since it has no
value type. And "oid_map" would become "oid_void" or similar (and
"oid_pos" becomes "oid_int"). That's better in some ways: it's more
regular, and a given map type can be more reasily reused in multiple
contexts (e.g., something storing an "int" that isn't a "pos"). But it's
also slightly less descriptive.

khash: drop broken oid_map typedef
Commit 5a8643eff1 (khash: move oid hash table definition, 2019-02-19)
added a khash "oid_map" type to match the existing "oid" type, which is
a simple set (i.e., just keys, no values). But in setting up the
khash_oid_map typedef, it accidentally referred to "kh_oid_t", which is
the set type.
Nobody noticed the breakage because there are not yet any callers; the
type was added just as a match to the existing sha1 types (whose map
type confusingly _is_ called khash_sha1, and it has no matching set
type).
We could easily fix this with s/oid/oid_map/ in the typedef. But let's
take this a step further, and just drop the typedef entirely. These
typedefs were added by 5a8643eff1 to match the khash_sha1 typedefs. But
the actual khash-derived type names are descriptive enough; this is just
adding an extra layer of indirection. The khash names do not quite
follow our usual style (e.g., they end in "_t"), but since we end up
using other khash names (e.g., khiter_t, kh_get_oid()) anyway, just
typedef-ing the struct name is not really helping much.
And there are already many cases where we use the raw khash type names
anyway (e.g., the "set" variant defined just above us does not have such
a typedef!).
So let's drop this typedef, and the matching oid_pos one (which actually
_does_ have a user, but we can easily convert it).
We'll leave the khash_sha1 typedef around. The ultimate fate of its
callers should be conversion to kh_oid_map_t, so there's no point in
going through the noise of changing the names now.

Also, this pointed out that our testsuite was lacking a good rename/add
