Only one fallback is possible for each event (INPUT, OUTPUT, CONNECTION, LOST)
INPUT: The function is called when there is at least a byte in the
input buffer
OUTPUT: The function is called when the system is sure the next write call
will not block
CONNECTION: Two cases is possible:
Client socket -> the connection is established
Server socket -> a client request a connection
LOST: the connection is lost
SetCallback accepts a combination of these flags so a same callback can
receive different events.
An event is generated only once and its state is reseted when the relative
IO call is requested.
For example: INPUT -> GSocket_Read()
CONNECTION -> GSocket_Accept()
