----------------------------------------------------------
Commit 70535eeb9b9c226129bdc96cbca8492fbc867cf6 in couchdb-fabric's branch
refs/heads/COUCHDB-3288-remove-public-db-record from [~tonysun83]

Use RealReplyCount to distinguish worker replies and invalid docs
We use {ok, []} in couch_db:open_doc_revs_int/3 as a return value
when the document does not exist and open_revs=all. This leads to an
incorrect all_workers_died error. We use ReplyCount and RealReplyCount
to distinguish between when no workers were actually used in a reply
versus when the document does not exist
COUCHDB-3113
> fabric:open_revs can return {ok, []}
> ------------------------------------
>
> Key: COUCHDB-3113
> URL: https://issues.apache.org/jira/browse/COUCHDB-3113
> Project: CouchDB
> Issue Type: Bug
> Reporter: ILYA
>
> According to typespec fabric:open_revs should return
> - {ok, #doc{}}
> - {{not_found,missing}, revision()}
> However in the case when the coordinator receive rexi_EXIT from multiple
> workers before the reply (for example when the worker crashes) the open_revs
> reply becomes \{ok, []}.
> This is due to the fact that we dispatch rexi_DOWN and rexi_EXIT recursively
> to handle_message(\{ok, Replies} [see
> here|https://github.com/apache/couchdb-fabric/blob/master/src/fabric_doc_open_revs.erl#L73
> clause]. Note that we set reply to be [] and worker to be nil.
