Prevent burst of reconnection attempts (#2251)
* Rate-limit new outbound peer connections

Set the rate-limiting sleep timer to use a delay added to the maximum
between the next peer connection instant and now. This ensures that the
timer always sleeps at least the time used for the delay.

This change fixes rate-limiting new outbound peer connections, since
before there could be a burst of attempts until the deadline progressed
to the current instant.

Fixes #2216

* Create `MetaAddr::alternate_node_strategy` helper

Creates arbitrary `MetaAddr`s as if they were network nodes that sent
their listening address.

* Test outbound peer connection rate limiting

Tests if connections are rate limited to 10 per second, and also tests
that sleeping before continuing with the attempts still respets the rate
limit and does not result in a burst of reconnection attempts.

Security: Avoid silently corrupting invalid times during serialization (#2149)
* Security: panic if an internally generated time is out of range

If Zebra has a bug where it generates blocks, transactions, or meta
addresses with bad times, panic. This avoids sending bad data onto the
network.

(Previously, Zebra would truncate some of these times, silently
corrupting the underlying data.)

Make it clear that deserialization of these objects is infalliable.

Add InventoryHash and MetaAddr proptests (#1985)
* Make proptest dependencies consistent between chain and network

* Implement Arbitrary for InventoryHash and use it in tests

* Impl Arbitrary for MetaAddr and use it in tests

Also test some extreme times in MetaAddr sanitization.

Move the preallocate tests into their own files (#1977)
* Move the preallocate tests into their own files

And move the MetaAddr proptest into its own file.

Also do some minor formatting and cleanups.
