Create md5 etag for _local docs
This makes a unique ETAG for _local docs, so that they are cached
correctly, and fetched again when the document changes.

> Stale ETags are re-used for _local docs

> Key: COUCHDB-2978
> URL: https://issues.apache.org/jira/browse/COUCHDB-2978
> Project: CouchDB
> Issue Type: Bug
> Components: HTTP Interface
> Reporter: Nolan Lawson
> Priority: Blocker
> Fix For: 1.7.0
>
>
> CouchDB re-uses the same ETags for _local documents even when the content of
> the _local document has changed, meaning that clients who cache based on the
> ETag may end up with permanently stale content. To reproduce the bug, it's
> simply:
> 1. Create a _local doc
> 2. Fetch the doc, ETag is "0-1"
> 3. Delete the database (or the _local doc)
> 4. Recreate the database (or the _local doc), insert a *changed* _local doc
> 5. Fetch the doc, ETag is still "0-1" and therefore the client may end up
> with a stale version.
