Streamline wxSocket code: wxSocketBase now uses wxSocketImpl (previously known

as GSocket) which is a base class with various wxSocketImplXXX implementations
provided by different wxSocketManagers.

Share more code between ports (still not finished).

Refactor some code inside wxSocketImpl itself to be less redundant and fixed a
couple of minor bugs in the process.
