Handling of connection-related message reception is currently scattered
around at different places in the code. This makes it harder to verify
that things are handled correctly in all possible scenarios.
So we consolidate the existing processing of connection-oriented
message reception in a single routine. In the process, we convert the
chain of if/else into a switch/case for improved readability.
A cast on the socket_state in the switch is needed to avoid compile
warnings on 32 bit, like "net/tipc/socket.c:1252:2: warning: case value
‘4294967295’ not in enumerated type". This happens because existing
tipc code pseudo extends the default linux socket state values with:
#define SS_LISTENING -1 /* socket is listening */
#define SS_READY -2 /* socket is connectionless */
It may make sense to add these as _positive_ values to the existing
socket state enum list someday, vs. these already existing defines.
