restore_creds uses prctl, so if we block this call in the seccomp filter
test, it causes things to fail (hang actually, seems we have some unhandled
error path here).

Running crit tool 4 times per test (decode, encode, decode --pretty
and encode back again) is way too slow. The majority of time, as
it turned out, goes on python load and arguments parsing. The en-
and de-coding works pretty fast.
So doing re-code logic in one python script for ALL images is way
way faster -- ~1 hour vs ~1 minute on my box.

When debugging it's useful to stop zdtm.py at certain points and
check what's going on out there. For this the --sbs (step-by-step)
option is introduced. It will make zdtm.py stop and wait for user
keypress before dump, before restore and after restore.

Right now zdtm spawns test into a pseudo-container and redirects its
output in a temp file. This is done not to mix outputs of tests, running
in parallel, with each other.
But if we run tests one by one or there's only one test in the list
we can safely print the output right on the screen.

Restore a receive queue in cases of:
1)socketpair with closed second end;
2)peer-less socket, who is a peer for others.
We use here a hack, it is the connect() with AF_UNSPEC family,
which clears peer of restoring socket. See unix_dgram_connect()
for the details.
This also makes socket_close_data test working.
SOCK_STREAM is supported in TCP_ESTABLISHED case in the same
function.

So here's the new test class that handles the test from
groups set. The class is inherited from zdtm_test one as
what it does is -- starts the pseudo-init in ns/uns flavors
and asks one to spawn() the sub-tests from the list.
All groups tests can only be run inside ns flavor, so if
the host flavor is asked, just the pseudo-init is spawned.
This is because using ns flavor is the easiest way to spawn
all the sub tests under this init (however, h flavor can be
supported by marking the pseudo-init as sub-reaper).
On stop this pseudo-init is signalled to stop, it in turn
stops all the sub-tests and then exits. When the pid
namespace destruction is complete, the sub-tests .out-s are
checked.

Introduce yet another tests set called 'groups'. Each test
in this set is a list of existing zdtm tests that can be
started side-by-side in an ns flavor.
To 'create' such a test the zdtm.py group action is used,
which lists tests and semi-randomly groups them together.
The grouping possibility is checked by comparing the .desc
files of those -- desc-s should coincide. One exception is
test dependencies, these are just merged together.
After running the group action there appears groups/ dir
with tests each containing just the list of zdtm tests
that are in a group. The respective .desc file is also
generated and this one matches the .desc for tests inside.

When starting inside ns flavor the test_init() routine prepares
the binary to be run inside namespaces. In particular this routine
fork()-s an init, execve()-s one to pick up mappings and exe from
the new mntns and then fork()-s the test itself. In order to go
back to test_init() for test initialization the execve() is done
again, but it's actually not required and confuses the reader.
