Semver Minor

• Added a new BSDSocket namespace, containing BSDSocket.OptionLevel and BSDSocket.Option for use when configuring socket options. (#1461, #1467, #1470, #1510) (Patch credit to @compnerd)
• Added BSDSocket.ProtocolFamily and BSDSocket.AddressFamily to replace the libc spelling for socket address families. (#1468, #1469) (Patch credit to @compnerd)
• Added ECN metadata to AddressedEnvelope. This functionality is currently unused, but will be enabled in a future release. (#1502)
• Added ByteBuffer.writeRepeatingByte method to provide a fast memset-like operation. (#1500)
• Added EventLoop.preconditionNotInEventLoop and EventLoop.assertNotInEventLoop to match existing EventLoop.preconditionInEventLoop and EventLoop.assertInEventLoop. (#1508) (Patch credit to @gwynne)
• Added MultithreadedEventLoopGroup.withCurrentThreadAsEventLoop to support taking over an existing thread and turning it into a NIO event loop. This allows NIO programs to now be single-threaded. (#1499)
• Added EventLoop.flatScheduleTask to provide a cleaner way to support a scheduled task that returns a future. (#1497) (Patch credit to @gwynne)
