[PATCH 15/20] Make sha1_array_append take a struct object_id *

["brian m. carlson" <sandals@crustytoothpaste.net>]

Convert the callers to pass struct object_id by changing the function
declaration and definition and applying the following semantic patch:

@@
expression E1, E2, E3;
@@
- sha1_array_append(E1, E2[E3].hash)
+ sha1_array_append(E1, E2 + E3)

@@
expression E1, E2;
@@
- sha1_array_append(E1, E2.hash)
+ sha1_array_append(E1, &E2)

@@
expression E1, E2;

- sha1_array_append(E1, E2->hash)
+ sha1_array_append(E1, E2)
