[PATCH 04/19] object-store: prepare read_object_file to deal with arbitrary repositories

From

As read_object_file is a widely used function (which is also regularly used in new code in flight between master..pu), changing its signature is painful is hard, as other series in flight rely on the original signature. It would burden the maintainer if we'd just change the signature.

Introduce repo_read_object_file which takes the repository argument, and hide the original read_object_file as a macro behind NO_THE_REPOSITORY_COMPATIBILITY_MACROS, which we planned for in e675765235 (diff.c: remove implicit dependency on the_index, 2018-09-21)

Add a coccinelle patch to convert existing callers, but do not apply the resulting patch from 'make coccicheck' to keep the diff of this patch small.
