Re: [GSoC][PATCH v15 3/9] fsck: make "fsck_error" callback generic

shejialuo [off-list ref] writes:

The "fsck_error" callback is designed to report the objects-related
error messages. It accepts two parameter "oid" and "object_type" which
is not generic. In order to provide a unified callback which can report
either objects or refs, remove the objects-related parameters and add
the generic parameter "void *fsck_report".

Create a new "fsck_object_report" structure which incorporates the
removed parameters "oid" and "object_type". Then change the
corresponding references to adapt to new "fsck_error" callback.

So since my last review, we've now changed the function to accept a
'void *' parameter, this makes sense, this way the refs error function
and the objects error function can now only receive the data they care
about.
