Track and report size of live data in DBs and views
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.
