If you try and do a difficulty of 1 the UInt256 class used for comparison throws
an error because 2^256 is 33 bytes. Instead use 2^256-1 which is 32.

* [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
* Update ethereum/p2p/src/main/java/tech/pegasys/pantheon/ethereum/p2p/rlpx/RlpxAgent.java

* Don't copy collections if we don't need to. Change types higher up if needed.
* Don't use Guava's Object.equal, use Java's Objects.equals.
** add errorprone test to enforce the banning of Guava's Objects class.

Only specify discovery port explicitly when the discovery port differs
from the listening port.

Biggest change is that UnusedVariable and UnusedMethod went to WARN by
default. Since our build is a no warning build this means we either need
to turn them off or fix them. I mostly opted for the latter. Test code
was mostly fixed, unused loggers were deleted, and other shipped code
was mostly suppressed.
Two less noisy fixes to not use `SortedSet` and to use zero based
comparable results instead of -1, 0, and 1. Also a compiler nit in
errorprone was suppressed, per the description it won't affect us.

Start P2P network synchronously so the ports are guaranteed to be known before we write the ports file
Include the P2P TCP port in ports file even when peer discovery is disabled.
Load information from the advertised peer rather than the discovery listening socket.
Fix admin_nodeInfo to include the ?discport param in the enode URI when the discovery port differs from the P2P port.

* Add the ipV6 flag to the datagram socket options, this creates a socket that handles both
ipv4 and ipv6 socket connections.
* Set the IPv6 flag state based on the presence or absence of an IPv6 address.
i.e. if your machine runs IPv6 it will accept IPv6 bootnodes and peers. However link-local IPv6 is not fully supported (see issue #288).

* Remove release/retain requirement from MessageData.
MessageData now wraps a BytesValue rather than a Netty ByteBuf so we no longer need to call release/retain and pass that through to the underlying ByteBuf.
Entirely removed support for a BytesValue wrapping a Netty ByteBuf as it does not provide any way to release the underlying ByteBuf.
* Add BytesValue.copyTo(byte[]) to avoid the need to call getArrayUnsafe() to copy the data.
