(a) Setting classic block to zero requires all blocks at zero to have the mainnet 1920000 hash. That will never happen. No clients will sync as long as this is in place
(b) a full sync fails

This includes code to address reading config for classic network and
kotti test network.
ClassicForkPeerValidator checks peers at classicForkBlock (same as Dao
Fork Block) and connects with peers that did not do the Dao Fork and
continued on the classic network.

When setting the p2p port to zero and turning on UPNP nat an attempt is
made to map port zero. This should actually map the opened port
instead.
The core logic is also now set up to throw an exception if a zero local
port is requested.

Update discovery logic to consider a peer with an unknown discovery endpoint to be unknown regardless of whether we've encountered a peer with the same node id before. This makes the discovery logic more forgiving in the face of node restarts.
If nodeA bonds with nodeB, then nodeB leaves the network and later comes back with a different ip address or listening port, nodeA would previously continue trying to communicate with nodeB at its original address. With these changes, nodeA will now treat the restarted nodeB as a new peer and communicate with it on its updated endpoint. Additionally, nodeB's information will be updated in the peer table so that neighbors requests return updated information on this node.

This reverts commit 814b36e4
The needed chantes to get rid of Instant.now (which is also needed to get rid
of the wall clock dependency) are too deep and intrusive into IBFT to try and
speed patch them in that some APIs require re-work, so in the interst of test
stability this gets sheleved until it is all ready.

To allow us to reset the timestamp in the blockchain for Retesteth support
we need to pass a Clock to affected APIs and use that instead of the static method
System.currentTimeMillis(). The most consistent way to do this that will ensure
that the API does not sneak back in is to ban the method via ErrorProne.
TestClock.fixed() was altered to return the "now" time of the first time the fixed clock was requested, needed for many header validation tasks validating headers are not from the future.

* [PAN-1683] Limit the fraction of wire connections initiated by peers
To protect against eclipse attacks, we should not allow all of our wire connections to be initiated from network peers. Some fraction of wire connections should be initiated by our node by connecting to peers in our discovery peer table. This PR ensures the fraction abides the limit.
* change fraction default value and add tests
* make fraction of remote wire connections configurable
- add a cli option to configure the fraction: `--fraction-remote-connections-allowed`
- introduce `Fraction` class to handle the conversion of the CLI option to a double and check if the value is between 0.0 and 1.0
- add tests
- fix broken tests
* remove unused local variable
* fix RunnerTest
* set fraction to 1.0 in PantheonFactoryConfigurationBuilder
* update test
* Introduce --limit-remote-wire-connections-enabled
* fix unused field
* fix conflict

Add support for working within Network Address Translation (NAT) environments.
This adds a CLI flag `--nat-method` with two options, `NONE` (the default and
current behavior) and `UPNP.` `--nat-method` will affect what IP address and
ports are advertised via the P2P discovery and other APIs that report the
address and port for P2P actions.
`UPNP` is intended for a typical home or small office environment where a
wireless router or modem provides NAT isolation.
