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.

Existing applications (such as those written for DAHDI) expect to
be reading data in buffer/chunk sizes. For example OsmoNITB: It
doesn't want to execute an expensive read/recv syscall to receive 11
bytes, if it needs at least 160 bytes.

This groups all HDLC-specific members together, in preparation
of adding more fields for other modes.

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

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.

SEQPACKET is great for preserving message boundaries on signaling
channels that use HDLC. However, its semantics, particularly regarding
truncation, are sub-optimal for RAW slots containing raw user
bitstreams (typically TRAU frames or PCM audio data).
So let's use SOCK_STREAM for RAW and keep SEQPACKET for HDLCFCS.

The idea is to generate a pair of virtual E1 interfaces (each with
identical number of lines), where each line A:n is connected to line B:n
of the pair and vice-versa.
This allows to test E1 using applications back to back against each
other, without any physical E1 circuits in between.

It is possible that fd=0 (stdin) is closed in a daemon scenario, and
subsequently fd=0 is reused for other files/sockets.

Let's add a VTY interface on TCP port 4269. The purpose is - for now -
not for configuration storage, but for state introspection.
