Networking

The game uses a UDP-based protocol. Unlike TCP, UDP does not guarantee that
packets arrive, or that they arrive in the correct order. For this reason,
the game protocol implements those features using the following:

* All packets have a sequence number that is utilized for reordering
* Important packets are wrapped in a SlottedMetaPacket with a subslot number
* RelatedA packets ae used to request lost packets using the subslot number
* RelatedB packets are used to confirm received SlottedMetaPackets

All of these go both ways, server <-> client. We used to only partially
implement these features: Outgoing packet bundles used SMPs and could be
resent, but not all packets were bundled and there was no logic for requesting
lost packets from the client and there was no packet reordering, which resulted
in dire consequences in the case of packet loss (zoning failures, crashes and many
other odd bugs). This patch addresses all of these issues.

* Packet bundling: Packets are now automatically bundled and sent as
  SlottedMetaPackets using a recurring timer. All manual bundling functionality
  was removed.

* Packet reordering: Incoming packets, if received out of order, are stashed and
  reordered. The maximum wait time for reordering is 20ms.

* Packet requesting: Missing SlottedMetaPackets are requested from the client.

* PacketCoding refactor: Dropped confusing packet container types. Fixes #5.

* Crypto rewrite: PSCrypto is based on a ancient buggy version of cryptopp.
  Updating to a current version was not possible because it removed the
  MD5-MAC algorithm. For more details, see Md5Mac.scala.
  This patch replaces PSCrypto with native Scala code.

* Added two new actors:
  * SocketActor: A simple typed UDP socket actor
  * MiddlewareActor: The old session pipeline greatly simplified into a
    typed actor that does most of the things mentioned above.

* Begun work on a headless client

* Fixed anniversary gun breaking stamina regen

* Resolved a few sentry errors

### Downloading PSCrypto
**The server requires binary builds of PSCrypto in order to run.** [Download the latest
*release](https://github.com/psforever/PSCrypto/releases/download/v1.1/pscrypto-lib-1.1.zip) and extract the the
*approprate dll for your operating system. If you are not comfortable with compiled binaries, you can [build the
*libraries yourself](https://github.com/psforever/PSCrypto).
sbt, IDEA, and Java will automatically find the required libraries when running the server. The build expects to find
the library in a subdirectory of the root directory called /pscrypto-lib/. Historically, we have recommended placing it
directly into the root directory and that has worked as well. If you still have issues with PSCrypto being detected, try
adding `-Djava.library.path=` (no path necessary) to your preferred IDE's build configuration with the library in the
root directory. For example, with IDEA: Run -> Edit Configuration -> (select the configuration) -> Uncheck "Use sbt
shell" -> VM Parameters

## Troubleshooting
#### Unable to initialize pscrypto
If you get an error like below
```
12:17:28.037 [main] ERROR PsLogin - Unable to initialize pscrypto
java.lang.UnsatisfiedLinkError: Unable to load library 'pscrypto': Native library (win32-x86-64/pscrypto.dll) not found in resource path
```
Then you are missing the native library required to provide cryptographic functions to the login server. To fix this,
you need a binary build of [PSCrypto](#downloading-pscrypto).
If you are still having trouble on Linux, try putting the library in `root directory/pscrypto-lib/libpscrypto.so`.

The way this test mediator works needs to be explained.
MDCContextAware objects initialize themselves in a chain of ActorRefs defined in the HelloFriend message.
As the iterator is consumed, it produces a right-neighbor (r-neighbor) that is much further along the chain.
The HelloFriend is passed to that r-neighbor and that is how subsequent neighbors are initialized and chained.
MDCContextAware objects consume and produce internal messages called MdcMsg that wrap around the payload.
Normally inaccessible from the outside, the payload is unwrapped within the standard receive PartialFunction.
By interacting with a TestProbe constructor param, information that would be concealed by MdcMsg can be polled.
The l-neighbor of the MDCContextAware is the system of the base.actor.base.ActorTest TestKit.
The r-neighbor of the MDCContextAware is this MDCTestProbe and, indirectly, the TestProbe that was interjected.
Pass l-input into the MDCContextAware itself.
The r-output is a normal message that can be polled on that TestProbe.
Pass r-input into this MDCTestProbe directly.
The l-output is an MdcMsg that can be treated just as r-output, sending it to this Actor and polling the TestProbe.

/**
* In between the network side and the higher functioning side of the simulation:
* accept packets and transform them into a sequence of data (encoding), and
* accept a sequence of data and transform it into s packet (decoding).<br>
* <br>
* Following the standardization of the `SessionRouter` pipeline, the throughput of this `Actor` has directionality.
* The "network," where the encoded data comes and goes, is assumed to be `leftRef`.
* The "simulation", where the decoded packets come and go, is assumed to be `rightRef`.
* `rightRef` can accept a sequence that looks like encoded data but it will merely pass out the same sequence.
* Likewise, `leftRef` accepts decoded packets but merely ejects the same packets without doing any work on them.
* The former functionality is anticipated.
* The latter functionality is deprecated.<br>
* <br>
* Encoded data leaving the `Actor` (`leftRef`) is limited by an upper bound capacity.
* Sequences can not be larger than that bound or else they will be dropped.
* This maximum transmission unit (MTU) is used to divide the encoded sequence into chunks of encoded data,
* re-packaged into nested `ControlPacket` units, and each unit encoded.
* The outer packaging is numerically consistent with a `subslot` that starts counting once the simulation starts.
* The client is very specific about the `subslot` number and will reject out-of-order packets.
* It resets to 0 each time this `Actor` starts up and the client reflects this functionality.
