Our CentOS based CI run is based on CentOS 7. CentOS 8 exists already
for some time and CentOS 7 will probably go end of life at some point.
This adds a CentOS 8 based CI run to be prepared for the time CentOS 7
goes away.

Raising an exception breaks out of the normal
flow of control of a code block. When an exception
is not handled, the interpreter terminates execution
of the program, or returns to its interactive main loop.

Most (all?) lazy tests are not being executed if "$KERN_MAJ" -ge "4" and
"$KERN_MIN" -ge "18". Currently most CI systems are running on something
with 5.4.x which means $KERN_MAJ is greater than 4 but $KERN_MIN is less
than 18 and so we are not running any lazy tests.
This commit removes the complete lazy test kernel version detection as
kernels on the CI systems are new enough to always have all required
features.

criu-ns performs double fork, which results in criu restore
using PID=2. Thus, if a user is trying to restore a process
with that PID, the restore will fail.

class ctypes.c_char_p
Represents the C char * datatype when it points to a zero-
terminated string. For a general character pointer that may
also point to binary data, POINTER(c_char) must be used.
The constructor accepts an integer address, or a bytes object.

So, here's the enhanced version of the first try.
Changes are:
1. The wrapper name is criu-ns instead of crns.py
2. The CLI is absolutely the same as for criu, since the script
re-execl-s criu binary. E.g.
scripts/criu-ns dump -t 1234 ...
just works
3. Caller doesn't need to care about substituting CLI options,
instead, the scripts analyzes the command line and
a) replaces -t|--tree argument with virtual pid __if__ the
target task lives in another pidns
b) keeps the current cwd (and root) __if__ switches to another
mntns. A limitation applies here -- cwd path should be the
same in target ns, no "smart path mapping" is performed. So
this script is for now only useful for mntns clones (which
is our main goal at the moment).

CRIU is already using multiple CI systems and not just Travis. This
renames all Travis related things to 'ci' to show it is actually
independent of Travis.
Just a simple rename.

Shellcheck (https://github.com/koalaman/shellcheck) can identify common
errors in shell scripts. This initial integration of shellcheck only
checks the scripts in the 'scripts/' folder. This commit fixes (or
disables) all reports of shellcheck to ensure this part starts error
free. I am not convinced this is really necessary as most changes do not
seem to be necessary for their circumstances. On the other hand it
probably does not hurt to use a checker to avoid unnecessary errors.

The docker hub container registry is not updated as fast as Fedora's
registry at registry.fedoraproject.org. Fedora's registry gets a new
image whenever there is a new version of rawhide, docker hub's rawhide
image can take a couple of weeks because the process is not automated.
Especially when Fedora branches of a new release we see lot's of errors
in CRIU's Fedora rawhide based Travis runs. Switch to Fedora's registry
to always have the newest rawhide images for our tests.

One of the most common CI errors we see is that package install fails
due to some hashsum mismatch or some DNS errors.
This adds a loop around each apt-get install call to do a clean, update
and install and if one of the steps fails it repeats it up to 10 times.

This adds the minimal configuration to run Fedora 31 based VMs on
Travis.
This can be used to test cgroupv2 based tests, tests with vdso=off and
probably much more which requires booting a newer kernel.
As an example this builds CRIU on Fedora 31 and reconfigures it to boot
without VDSO support and runs one single test.

One can pass --stream to zdtm.py for testing criu with image streaming.
criu-image-streamer should be installed in ../criu-image-streamer
relative to the criu project directory. But any path will do providing
that criu-image-streamer can be found in the PATH env.
Added a few tests to run on travis-ci to make sure streaming works.
We run test that are likely to fail. However, it would be good to once
in a while run all tests with `--stream -a`.

See "man memfd_create" for more information of what memfd is.
This adds support for memfd open files, that are not not memory mapped.
* We add a new kind of file: MEMFD.
* We add two image types MEMFD_FILE, and MEMFD_INODE.
MEMFD_FILE contains usual file information (e.g., position).
MEMFD_INODE contains the memfd name, and a shmid identifier
referring to the content.
* We reuse the shmem facilities for dumping memfd content as it
would be easier to support incremental checkpoints in the future.

It seems like Ubuntu introduced a overlayfs change which breaks CRIU:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1857257
This disables overlayfs (unfortunately) in most tests by switching to
devicemapper or vfs.
Upstream kernels do not seem to have this problem.
This also adds the 'docker-test' for xenial which still has a working
overlayfs from CRIU's point of view.
Also adjust Podman Ubuntu package location
Podman Ubuntu packages are now available via OBS and no longer via PPA.
