The class |UnixSocketIOBuffer| maintains memory buffers for socket I/O
operations. The actual I/O is still implemented by subclasses, such as
|UnixSocketRawData|.
This patch moves the I/O operations for sending and receiving data
in |SocketIOBase| into |UnixSocketRawData|. This change allows to
add a clean interface to |UnixSocketRawData| and later replace the
class by other implementations.
|SocketIOBase| is a base class for Socket I/O classes. It's not a
requirement, but provides a number of helpful methods for common
I/O operations on the I/O thread.
|SocketConsumerBase| handles connection state for |UnixSocketConsumer|
and its derived classes. Implementing classes must override a number of
virtual methods, to handle notifications about changes to the state of
the connection.
