Improved _active_tasks API
Tasks are now free to set any properties they wish (as an
Erlang proplist). Different tasks can have different properties
and the status string doesn't exist anymore - instead client
applications can build it using more granular properties from
_active_tasks. Some of these properties are:
1) "progress" (an integer percentage, for all tasks)
2) "database" (for compactions and indexer tasks)
3) "design_document" (for indexer and view compaction tasks)
4) "source" and "target" (for replications)
5) "docs_read", "docs_written", "doc_write_failures",
"missing_revs_found", "missing_revs_checked", "source_seq",
"checkpointed_source_seq" and "continuous" for replications

We were pulling a list of design documents and then ignoring the result
when the #db was a partition of a clustered database. Also, the call to
fabric:reset_validation_funs/1 can occasionally cause a stray rexi_EXIT
message to arrive in the db_updater mailbox (and subsequently kill the
server) if a worker fails. I don't think that's desired behavior,
though it's a debatable point. This patch spawns a middleman process to
act as a sink for those stray messages.

1) couch_file:sync could leave open fd's if close failed. Now we'll get a trace.
2) couch_file:append_term failing would be bad, so let's test that too.

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.

- 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).
