Claudiu Olteanu a6274a3a55 Add set_timeout callback for serial custom implementation
The new callback will be usefull when we will implement the support
for Windows. The implementation of native serial set_timeout method
uses a HANDLER on Windows and we will use the WinSock2 API which has
a socket descriptor.
