MEDIUM: connection: centralize handling of nolinger in fd management

Right now we see many places doing their own setsockopt(SO_LINGER).
Better only do it just before the close() in fd_delete(). For this
we add a new flag on the file descriptor, indicating if it's safe or
not to linger. If not (eg: after a connect()), then the setsockopt()
call is automatically performed before a close().

The flag automatically turns to safe when receiving a read0.
