manifest.c: new extension code to lazily parse manifests
This lets us iterate manifests in order, but do a _lot_ less work in
the common case when we only care about a few manifest entries.
Many thanks to Mike Edgar for reviewing this in advance of it going
out to the list, which caught many things I missed.
This version of the patch includes C89 fixes from Sean Farley and
many correctness/efficiency cleanups from Martin von
Zweigbergk. Thanks to both!
