The #full_doc_info record is extended to include the summed size of
leaf revision document bodies and their attachments. Document sizes
are computed on update; accurate sizes of existing databases and
view groups are only available after compaction.
The document size is defined to be the size of the binary
representation of #doc.body. The att_len field is used for
attachments; attachments that are shared by multiple revisions of a
document are only counted once. The size of a view index is defined as
the size of all keys, values, and reductions accessible from the current
root of the tree.

A new config setting is introduced. The following block controls the
maximum number of OS processes that will be reused. Additional OS
processes will still be spawned on-demand, but they'll be terminated
when the clients are through with them.
[query_server_config]
os_process_soft_limit = 100

- Removal of couch_db and couch_ref_counter processes. Active DBs are
accessible through a protected ets table owned by couch_server.
- #full_doc_info{} in by_id and by_seq trees for faster compaction at the
expense of more disk usage afterwards. Proposed as COUCHDB-738 but not
accepted upstream.
- Replication via distributed Erlang.
- Better hot upgrade support (uses exported functions much more often).
- Configurable btree chunk sizes allow for larger (but still bounded)
reductions.
- Shorter names for btree fields in #db{} and #db_header{}.
- couch_view_group does not keep a reference to the #db{}.
- Terms are stored compressed (again).
