From 3c8dea1f8d7c4257d080f9f34159cdb2fffb81e6 Mon Sep 17 00:00:00 2001

Subject: Change project.revision to revisionExpr and revisionId

The revisionExpr field now holds an expression from the manifest,
such as "refs/heads/master", while revisionId holds the current
commit-ish SHA-1 of the revisionExpr.  Currently that is only
filled in if the manifest points directly to a SHA-1.
