[Serdev] TCP connection reuse

[samuel]

In SER stable version you are forced to change the define and
recompile the server  to modify the connection lifetime.

New SER version (ottendorf/ 2.0 ;) ) has a new configuration parameter
so you can modify the TCP behaviour without having to recompile SER:

tcp_connection_lifetime=20


Hope it helps,

Samuel.
