LMGCDAsyncSocketMiddleware

A middleware for CocoaAsyncSocket's TCP GCDAsyncSocket.

Note: while this code has been in production in Paw for a while, it still needs structural improvements to be a nice library. Also, some unit tests would be very useful. Contributions are more than welcome! :)

Improvements over GCDAsyncSocket

• Implements the Happy Eyeballs Algorithm to connect to the fastest host (IPv4 or IPv6) when both are returned by the DNS server
• Wraps nicely all read operations (read until a data has been found, read a given number of bytes, read until connection close)
• Wraps GCDAsyncSocket, so the caller can abstract itself from other details
• Adds a new delegate callback didResolveHostnameWithIPv4Address: as soon as DNS resolution happens
