![Jeff King](/assets/img/avatar_default.png)
In preparation for unifying the handling of alt odb's and the normal repo object directory, let's use a more neutral name. This patch is purely mechanical, swapping the type name, and converting any variables named "alt" to "odb". There should be no functional change, but it will reduce the noise in subsequent diffs.
