Steffen Müller tsee Experimental support for on-expiration messaging for strings
With this change, the Redis server will dispatch a 0MQ message whenever
a key (of simple string type) expires. This is useful when using
Redis as a persistent, reliable hot cache and the data needs to be
expired into a cold storage solution.

0MQ was chosen for simplicity, low overhead and high message throughput
so that Redis isn't slowed down significantly.

Steffen Müller tsee Bind to the 0MQ endpoints and send PUSH messages
Used to be connect() and PUB, but it turns out that this being the
server, it's easier to write clients that deal with disappearing
endpoints.

Steffen Müller tsee Hack towards dumping with simple protocol
1st frame: Header of dbno and value type
2nd frame: Key string
3rd frame: Value

A string is dumped as (size_t)length and length bytes of string.
The interpretation of the value depends on the value type, which
is either a string as per above, or a has encoded as:
  - (size_t)nhashkeys
  - nhashkeys alternating key/value pairs
    => key and value both being a string as per above

The hash dumping is not implemented yet.

Steffen Müller tsee First stab at implementing expire looping
In a nutshell, this feature will enable stuffing a hash back into Redis
when it expires, while resetting expiration and keeping track of how
often it has done the expire loop. Eventually, when that counter hits a
configurable limit, it won't be reinserted.

This is useful as a oh-my-god-is-this-painful workaround for both
unreliable messaging and the
this-key-is-in-flight-and-not-available-from-anywhere race condition.
The worker processes that pick up the expired messages are expected
to issue an explicit delete from Redis when they've successfully
inserted the record into the long term storage. That breaks the cycle.
