Harald Welte 5523be4594 contrib/ Build e1-tracer host software
Run the different job types based on a new environment variable, as the
software has to be built with a different docker image. The related
osmo-ci patch adjusts the jenkins jobs accordingly.

Harald Welte 6cb6e6ec15 fw/e1-tracer: Initialize IDT82V2081 from within firmware in e1d mode
Initially it was a good choice to keep the LIU driver in the host
software (easier debugging/changes).  However, we never really needed it
to do anything but initialization of the LIU.

So in order to avoid having to teach osmo-e1d or other software the
details about the LIU initialization, let's do this from the firmware
*if* the e1d compatible USB configuration is used.

Harald Welte f9280b0de1 fw/e1-tracer: Additional USB configuration for "osmo-e1d compatible mode"
This adds a second USB configuration to the e1-tracer firmware.  This
configuration is closer to the USB configuration of an icE1usb and hence
paves the way for using osmo-e1d with the tracer.

The main conceptual difference between the existing "legacy"
configuration and this new "e1d compatible" configuration is to have two
USB interfaces, one for each direction of the traced E1 interface.  Each
interface has its own separate two altsettings, one for the disabled
and one for the enabled state.

Unmodified osmo-e1d will not work straight away with this, as it expects
ISO OUT and ISU Feedback endpoints, which a pure rx-only tracing device
of course doesn't have.

Harald Welte 326a08fe63 fw/e1-tracer: e1_start/e1_stop of individual channel
Let's split the starting and stopping between the two channels.

This is a preparation for a future e1d-compatible mode where each
channel (direction) has its own USB interface and hence must be
individually started/stopped.

    I get LIBUSB_TRANSFER_ERROR every so often (once every few hours) on my
    laptop.  Sure, it likely means there was some data lost, but the trace
    can continue juts fine after this error.  So make it non-fatal and
    continue running.

Now after some testing, I implemented a PID loop that seems to
present faster lock time and at least as good stability.

Parameters were not thorougly optimized just some 'hand' tuning
trying to simulate the behavior.
