This adds the 'osmo-e1d-pipe' utlility program, which can be
used as a command-line client to open a given E1 timeslot and
connect it to stdin/stdout. This in turn allows to rediect
file input/output via the shell.

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.

'struct e1_ts' always had a back-pointer to the line it is part of,
but apparently this was never initialized so far.

We always want to know as much context as possible. Which exact
timeslot on which line of which interface ha logged something?

If the user application has closed the timeslot socket, we will
get error returns from read/write calls, which we must use to clean
up the daemon-side state for this timeslot.

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

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

By using llist_add_tail(), we add new elements at the end of the list,
rather than inserting at front. Among other things, this has the added
benefit that when the VTY prints information on lines, they are printed
in numerically ascending orrder (0,1,2, ...) and not the reverse.

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

libosmousb, recently introduced to libosmocore.git, is taking care
of main loop integration of libusb into osmo_select_main(). This
means we don't need to do any polling here anymore.

The idea of this code is to check captures made by ICE40 against
the known transmitted per-timeslots PRBS sequences.

e1-prbs-test is a small utility that can be used to do PRBS testing
on E1/T1 lines using DAHDI cards. A transmiter and receiver are
exchanging timeslot-specific PRBS sequences.
