repeating information

Update instructions and CI for cross-compilation on Ubuntu 22.
Note that for the dockerfile, we use egrep -L which has changed and does
not exit with code 0 on no match. Instead, use -vqz to invert return
code (0 if nothing found, otherwise 1).
iperf2 2.0.13, used in Ubuntu 20, does not need a "back channel"; we can
therefore use it in feMBMS (which does a broadcast, without back
channel). Ubuntu 22 comes with 2.1.5, which seems to require a back
channel, or at least, we cannot use it reliably in feMBMS. Hence,
downgrade to older iperf2 version.

This updates all images in the CI to Ubuntu 22. It also updates
corresponding documentation. Remove python(2) from the image, as it is
not needed. Update documentation.
It seems that the gcc coming in Ubuntu 22 does not like
stack-protector-strong, so remove it as well.
Since we compile Flexric, which does not support Ubuntu 22's default
gcc-11 (it hits a compile bug), switch to gcc-12 manually.
Since we update the compiler, we also need to be careful to use the right
address sanitizer version (which is bundled with the compiler version).
To avoid a reinstallation of the wrong asan version in target images, we
modify Ubuntu 22 targets to copy libasan from the base image. This is necessary
since we use update-alternative in the base image, but we don't want to
install compilers in the target images to use update-alternatives to
install the right asan version... This should be undone when switching
to Ubuntu 24 in the future, as it will have a newer default gcc version,
such that we don't need to update the compile in the first place.
Upgrade libpython in lteUE for U22 upgrade to make it compatible with
UHD.
A number of warnings appear when compiling flexric with gcc-12, which we
use in the next commit. Those have been fixed upstream. Switch to the
updated version to avoid warnings.
It seems libatlas-base-dev provided an `enum CBLAS_TRANSPOSE`, but we
don't install it anymore. Now, in Ubuntu, there is only a typedef'd
version in cblas.h; for RHEL(-derivatives), the same typedef'd version
is in cblas/cblas.h.
Ubuntu 18.04 is now in "Extended Security Maintenance", but otherwise
gets no updates. Remove it from supported distributions (regarding
installing packages); users can of course still use it.
Users are encouraged to upgrade to Ubuntu 20+.
Apart from the obvious change of adding ubuntu24.04 to supported
distributions, we need to remove liblapacke-dev as it is incompatible
with libatlas3-base. Installing both aborts with:
The following packages have unmet dependencies:
liblapacke : Breaks: libatlas3-base (< 3.10.3-14) but 3.10.3-13ubuntu1 is to be installed
It seems that we don't need it though, as liblapacke-dev installs the
right atlas library as a dependency.
Fix small issue noted when packing tlv value with tag 1 in which it would pack length*4 bytes, now calculated how many "segments" of 32 bits it needs to pack, same logic for unpacking tag value 1
Added missing support for packing/unpacking tag 0x001C (supportedMaxModulationOrderDl)
Now properly handles tag 0x0005 (NumConfigTLVsToReport) and subsequent TLVs that come after this value ( Table 3-9 SCF 222.10.02 )
Implement FAPI P5 message unpack, as well as message length check function procedure in FAPI P5 library.
Update check_nr_unpack_length in nfapi_p5.c to reference FAPI P5 message length check function.
Will be reused from other files in later commits.
Added packing/unpacking procedures for STOP.indication and ERROR.indication.
Separate a packing function for STOP.request for use in the NR FAPI library.
