Commit 860f23cb57e0af84b668609676ba93c5edb769d5 in couchdb's branch refs/heads/master from [~eiri]

Fix _local_docs end-point

This is a second attempt to fix _local_docs end-point. The previous one didn't
work on big enough btree_local, because local btree doesn't have reduction fun,
so reuse of couch_db_updater:btree_by_id_reduce/2 was crashing on a bad match
as soon as btree_local was getting kp_node. Also using full fold to calculate
total_rows value turned out to be resource expensive when a database have
significant number of local documents.

This fix avoids calculating of total_rows and offset instead always setting
them to null and also setting to null update_seq when requested, since it
doesn't have meaning in context of local documents.

A fabric module fabric_view_all_docs.erl was copied and modified as
fabric_view_local_docs.erl, because re-using it for processing of both types of
the documents was getting rather convoluted.
