the code creates a sink to read all traced packets and drop it.  but
this works only if we send to a local address and if there is not
another sink (like if we trace both UE and gNB in the same machine).
this sink's purpose is only to prevent to get automatic packets back
from the kernel saying "no listener". So, instead of killing the trace
when we can't create the sink (as done previously), we now just let the
trace in operation.

See e.g., egrep(1) [https://linux.die.net/man/1/egrep]:

> two variant programs egrep and fgrep are available. egrep is the same
> as grep -E. fgrep is the same as grep -F. Direct invocation as either
> egrep or fgrep is deprecated

See also the rationale of the POSIX description of grep
(https://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html):

> This grep has been enhanced in an upwards-compatible way to provide
> the exact functionality of the historical egrep and fgrep commands as
> well. It was the clear intention of the standard developers to
> consolidate the three greps into a single command.

The default values set by xran for DPDK socket memory/limit is 8192. It
is changed when the variable for the memory size, given down to xran, is
non-zero (cf also previous patch). Since the last patch, if nothing is
given in OAI configuration, OAI will pass down a size of 8192. However,
a configuration value of 0 is a valid choice (it is a pre-allocation,
DPDK will allocate dynamically), so modify the default in xran to be 0
so that all sizes, including 0, can be given to DPDK.

Note that the currently used implementation of xran will always try to
allocate this memory on NUMA node 0. If you want to use another one,
this field has to be set to 0 (no pre-allocation), and DPDK will
allocate it dynamically.

xran has a mechanism to request DPDK to allocate a configurable amount
of bytes for huge pages. We set it to 0 until now; expose this variable
through configuration, and provide a meaningful default 8192 MiB.
Provide documentation.

Mapping of data REs in DMRS symbol depends only on number of CDM group
no data. So the special case function that depended on delta is removed
and a single function is used.

like this:

  /oai-ran/openair3/SECU/snow3g.c:429:23: runtime error: left shift of 232 by 24 places cannot be represented in type 'int'

To use:

    cd <top directory of openair>
    mkdir build
    cd build
    cmake .. -GNinja -DENABLE_TESTS=ON
    ninja tests (alternatively: ninja snow3g_tests)
    ctest (alternatively: ctest -R snow3g_tests)

Build on ARM fails in the previous version, while the current master
(1a09d3bc) works. So let's update to a newer version to avoid problems
on ARM, and assuming x86 works.

- Better trace DLSCH decoding result
- Rename the decode result variable to separate with later ack/nack
  encode of this decoding result from 3GPP (not trivial true=1 coding)
- Cleanup decodeResult usage
- Remove unused defines
