There are several places where users may want to specify the type of object IDs (sha1 or sha256) that should be used, for example, when dealing with repositories, indexes, etc. However, given that sha256 support remains disappointingly uncommon in the wild, we should avoid hard API breaks when possible. Instead, update these APIs to have an "extended" format (eg, `git_odb_open_ext`) that provides an options structure with oid type information. This allows callers who do care about sha256 to use it, and callers who do not to avoid gratuitous API breakage.
