Add a /replication API for extracting the updates that happened on

synapse

This is necessary for replicating the data in synapse to be visible to a
separate service because presence and typing notifications aren't stored
in a database so won't be visible to another process.

This API can be used to either get the raw data by requesting the tables
themselves or to just receive notifications for updates by following the
streams meta-stream.

Returns updates for each table requested a JSON array of arrays with a
row for each row in the table.

Each table is prefixed by a header row with the: name of the table,
current stream_id position for the table, number of rows, number of
columns and the names of the columns.
This is followed by the rows that have been added to the server since
the requester last asked.

The API has a timeout and is hooked up to the notifier so that a slave
can long poll for updates.

HTTP endpoint for extracting data from synapse.
The streams of data returned by the endpoint are controlled by the
parameters given to the API. To return a given stream pass a query
parameter with a position in the stream to return data from or the
special value "-1" to return data from the start of the stream.
If there is no data for any of the supplied streams after the given
position then the request will block until there is data for one
of the streams. This allows clients to long-poll this API.
The possible streams are:
* "streams": A special stream returing the positions of other streams.
* "events": The new events seen on the server.
* "presence": Presence updates.
* "typing": Typing updates.
* "receipts": Receipt updates.
* "user_account_data": Top-level per user account data.
* "room_account_data: Per room per user account data.
* "tag_account_data": Per room per user tags.
* "backfill": Old events that have been backfilled from other servers.
The API takes two additional query parameters:
* "timeout": How long to wait before returning an empty response.
* "limit": The maximum number of rows to return for the selected streams.
The response is a JSON object with keys for each stream with updates. Under
each key is a JSON object with:
* "postion": The current position of the stream.
* "field_names": The names of the fields in each row.
* "rows": The updates as an array of arrays.
There are a number of ways this API could be used:
1) To replicate the contents of the backing database to another database.
2) To be notified when the contents of a shared backing database changes.
3) To "tail" the activity happening on a server for debugging.
In the first case the client would track all of the streams and store it's
own copy of the data.
In the second case the client might theoretically just be able to follow
the "streams" stream to track where the other streams are. However in
practise it will probably need to get the contents of the streams in
order to expire the any in-memory caches. Whether it gets the contents
of the streams from this replication API or directly from the backing
store is a matter of taste.
In the third case the client would use the "streams" stream to find what
streams are available and their current positions. Then it can start
long-polling this replication API for new data on those streams.
