feat: TCP Transport Layer #1636
Conversation
* Optionally compiled additional TCP transport layer. * Config to enable it. * Tested and functional with lcdr's tcpudp dll, udp being disabled in the dll due to port issues. * Removed unused RakNet replica manager and id manager. We've got our own replica manager since pre-open-source. * Utilizes async boost behavior. Todo: * Figure out how to do ping calculations. * Fix crashes on universe shutdown. * Test TLS on a VPS. * Remove unnecessary logging. * Test with lots of clients. * Finish "master" to "manager" naming refactor.

consider checking that packet->data is not a nullptr and also that the packet passed into here is a valid pointer as well

Is there a particular reason for this define?

Consider WriteBytes here

This could access undefined heap memory if data is < 5 in size, i would consider bounds checks here on a packet

on platforms where size_t is 32 bits, this will result in just being hash1 always. a 32 bit shift on a 4 byte value also is not a valid operation which is worth considering for a different hash value
TCP Transport Layer
Scope
This PR seeks to add an alternative TCP transport protocol. It works under the specifications of lcdr's tcpudp shim dll. The protocol initially specified the use of UDP for unreliable packets, but this is disabled in the dll due to port issues. This feature PR will assume this disabled state is permanent; UDP for unreliable packets will not be enabled.
