Adding RPC Framework Generator

Changes

• Moving github.com/loopholelabs/packet into Frisbee under github.com/loopholelabs/frisbee/pkg/packet
• Added pkg/metadata and pkg/content packages to work with the pkg/packet package
• Added initial version of protoc-gen-frisbee CLI for generating an RPC Framework with Frisbee

Updating Contexts

Changes

• Update packet to v0.2.5
• Added UpdateContext function for both the server and client

Bug Fixes and Refactors

Fixes

• Closing a connection doesn't mean the other side loses data it hasn't reacted to yet

Changes

• A Drain function was added to the internal/queue package to allow the killGoroutines function in async.go to
  drain the queue once it had closed it and once it had killed all existing goroutines
• The heartbeat function in client.go was modified to exit early if it detected that the underlying connection had
  closed
• The async connection type was modified to hold stale data once a connection is closed. The killGoroutines
  function will drain the incoming queue after killing all goroutines, and store those drained packets in
  the async.stale variable - future and existing ReadPacket calls will first check whether there is data available in
  the stale variable before they error out
• Refactored the handlePacket functions for both servers and clients to be clearer and avoid allocations
• The close function call in Async connections was modified to set a final write deadline for its final writer flush

Refactoring Packets and fixing ConnContext

Merge pull request #69 from loopholelabs/staging

Release v0.2.1

PacketContexts and Garbage Collection

Fixes

• pkg/ringbuffer (now called pkg/queue) no longer goes into an invalid state when it overflows
• Many new test cases for the pkg/queue package
• Multiple Goroutine leaks

Changes

• Frisbee now reuses byte slices reducing GC pressure with a new *packet.Packet interface
• pkg/queue now has both Blocking and Non-Blocking functionality with differing performance
• Benchmarks have been modified to be more thorough and compare performance with raw TCP Throughput
• Handler function signatures no longer differ between Server and Client routing tables, and no longer include connections being passed into the handler
• ConnContext and PacketContext functions have been added to allow the context.Context package to be used within Handler functions

New Features and Increased Stability

Features

• Adding TLS functionality to Frisbee servers and clients
• Separating Frisbee Connections into Synchronous and Asynchronous connections
• Create multiplexed streams on top of existing frisbee connections (Async connections only)

Fixes

• Frisbee Server and Client now wait for goroutines to close when they are closed
• Frisbee read loop and write (flush) loops implement deadlines

Changes

• Frisbee Message ID field is now a uint64 (which makes UUID generation easier)
• TestStreamIOCopy now uses net.Conn instead of net.Pipe for testing
• Removed Buffer messages (for raw data), replaced them with multiplexed streams

Improving test stability, adding io.Writer and io.Reader compatibility to frisbee.Conn

Features

• Adding Write, Read, WriteTo, and ReadFrom functionality to frisbee.Conn to make it compatible with io.Copy
  functions

Fixes

• Improving README.md with public build status
• Improving test case stability

Changes

• Read and Write functions are now called ReadMessage and WriteMesage respectively
