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.

Whenever the RIFO buffer fill drifts away from its target, it can be
automatically reset and filled to the initial prefill_frame_count value.
The average fill is measured over several seconds. A given deviation
in percent of the prefill_frame_count is used to trigger that reset.
If the deviation is not set (0), this feature is deactivated.
There are two reasons for this to happen: The GPS clock is missing, so
the receiving interface is not in sync with the transmitting interface.
The delay changes significantly, due to congestion on the path between
both peers. (poor internet connection)

This new mode (can be enabled per account) will force the E1OIP
protocol to always send all timeslots, i.e. not do any of the
suppression of timeslots that do not exhibit any change to the
previous E1 frame.

The function prototype for osmo_e1dp_client_destroy has a different
parameter name in its signature in proto_clnt.h than in prto_clnt.c,
let's rename it so that both are coherent. (srv -> clnt)

DAHDI trunkdev is a newly-introduced 'virtual trunk' character device
which is used instead of a real hardware driver. This means that an
application (such as osmo-e1d) can implement a virtual E1 trunk and
receive and transmit E1 frame data which is exposed to DAHDI users
just like the data from a real physical E1 span.
In order to build DAHDI trunkdev support into osmo-e1d, you will need
a special fork of dahdi containing the required support, currently
the laforge/trunkdev branch of the following repository:
https://gitea.osmocom.org/retronetworking/dahdi-linux

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.

This adds VTY commands at the 'account' level to configure those
settings. They will only become active on the next [re]connect
of the line.

Let's allow setting IP DSCP and socket priority via the VTY.
Note that you must still manually add a kernel egress QoS map from
socket priority to IEEE P802.1p PCP (Priority Code Point) like this:
ip link set dev eth0.7 type vlan egress-qos-map 0:0 1:1 5:5 6:6 7:7
This will create 1:1 mappings for socket priorities 0, 1, 5, 6 and 7 to
the respective IEEE PCP. A higher PCP typically means higher priority,
where voice is traditionally using "5".

This introduces initial support for operation as OCTOI (Osmocom
Community TDMoIP) server and client operation.
Various features are still absent (user authentication, support for
re-ordered packets), but this version is already able to provide
services to clients with dynamic IP addresses as well as servers.
The bulk of the OCTOI / E1oIP code is implemented as a shared library,
to facilitate the development of other servers and clients in the
future, and also to minimize the impact on the existing osmo-e1d code
base.

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.
Closes: OS#4654

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.
Change-Id: I765b5c3bc9e07b2353f8647e8260ff95df3727e6
We treat the superchannel as an extra, separate timeslot. Initially
I thought of simply re-using TS1, but keeping the superchannel
separate ensures that it doesn't inherit any state (like half-sent
HDLC frames) from another timeslot when we switch between the modes
at runtime.

This way clients and daemon don't have to be manually configured
to use the same default socket path.
