sha1_file: convert sha1_object_info* to object_id

Convert sha1_object_info and sha1_object_info_extended to take pointers
to struct object_id and rename them to use "oid" instead of "sha1" in
their names.  Update the declaration and definition and apply the
following semantic patch, plus the standard object_id transforms:

expression E1, E2;

- sha1_object_info(E1.hash, E2)
+ oid_object_info(&E1, E2)
