I visually inspected patches 1 and 2 without finding any problems.
Regarding this patch, I saw a few functions where you could convert
local variables to "struct object_id" and then change function calls
like hashcpy() to oidcpy(). See below. I'm not sure if it makes sense to
do that in this same patch.
For that matter, it seems to me that it should be possible to change
*all* local
unsigned char $variable[20];
to
struct object_id $variable;
without having to change any external interfaces. I wonder whether it
would be advisable to make that change early in this transition? It
would have the advantage that during later refactorings, where, e.g., a
function needs a "struct object_id *" parameter, you would often already
have one handy.

Variable "sha1" in this function could become "struct object_id".

old_sha1 in this function could become "struct object_id". Also, this
function has a few "20" and "41" and "42" hard-coded literals.

old_sha1 in this code block could be converted to "struct object_id".

The "sha1" variable in this function could become a "struct object_id".

This could become oidcopy().
