The client may register a callback function to receive events.
Because there is no relation between the connected client and the
interface, all events are broadcasted to all clients that are
connected to the server.

When the socket is closed due to a connection loss, we currently use
close(). This is not enough since this will not remove the file
descriptor from the select loop. Let's use osmo_fd_close.

When osmo-e1d is terminated the socket file descriptor on the client
side will get permanent POLLHUP events. This means that the registered
callback gets called with flags OSMO_FD_READ but the received data will
be of length zero. We must detect this situations and close the file
descriptor on connection loss. Otherwise we would get called over and
over again in an endless loop, resulting in 100% CPU usage.

If we actually expect 3rd party applications to use libosmo-e1d to talk
to osmo-e1d, we'd better add some basic documentation on how this API
shall be used.

Align the behavior of osmo-e1d with that of DAHDI: If a timeslot is
opened once, it cannot be opened again by anyone until it is closed
by the current owner. This way we'd have the same failure semantics
in DAHDI vs. osmo-e1d, which is very useful in case of misconfiguration
when osmo-bsc + osmo-mgw would "fight" over a timeslot.
Add a osmo_e1dp_client_ts_open_force() function that allows to override
and get back the original behavior.

When opening a timeslot, the client can now specify the (from
application perspective) timeslot read buffer size. This breaks
ABI, but then we're still at a point where only prototype hardware
exists, so we can get away with it.

This adds the related code to the server and client side of the CTL
interface to switch a line between CHANNELIZED and SUPERCHANNEL.
