To run CRIU with ASan we have to use some non-default options:
- detect_leaks=0 - We have to many leaks for know. Let's disable until fixed.
- disable_coredump=0 - without this ASan library changes RLIMIT_CORE which
break rlmimits00 tests.
- log_path=asan.log - For some reason default output to stderr sometimes
doesn't work in CRIU. So error log will be stored
in asan.log.<pid> file instead.

For 32-bit fcntl() Glibc function calls sys_fcntl64(), which
needs struct flock64, otherwise the kernel gets a wrong struct.
For 64-bit, it's all the same.
Also unset errno before fcntl() and check return value of the call.

Yet they only test for ELF header, but soon I'll add more of them.
It's build with

and test output is in TAP format:
$ ./test/compel/handle_binary
ok 1 - check zero ELF header
ok 2 - check non-supported ELF header
ok 3 - check non-relocatable ELF header
ok 4 - check zero ELF header
ok 5 - check non-supported ELF header
ok 6 - check non-relocatable ELF header
(here two runs for x86_64 and x86_32 ELF binaries)
I'm planning to integrate it with Travis, so we will be
sure that compel is properly working (as this tests doesn't need
any ns and may be run on qemu-static).

cat *.pid works when we have only one running process at any moment.
That's because pidfiles contain no newlines and cat will just
concatenate content of all files present in directory. So, e.g., if we
have pidfiles:
31338
31359
31880
31884
31889
cat will build following string from those pidfiles:
3133831359318803188431889
Obviously, kill would fail to send signals to processes, because it's
now a single big number, which cannot be unambigously split back in
general case.
That's where awk comes in. We don't need to modify C part of tests to
print newlines at end of file. We just order awk to print content of
each file, which adds a newline at end - problem solved, kill can once
again parse, which PIDs it get and send proper signals to them. Also,
should be completely safe for zdtm.py, because it doesn't use Makefiles
and sends signals on it's own.

For ZDTM purposes, poll.c uses delta of 5 seconds, which is fine, since
tests don't take a very long time to pass. However, in vzt-cpt, we start
a batch with multitude of tests and starting them all could take over an
hour. Hence, the test is bound to fail. An easy solution would be to
introduce an environment variable, which would allow to specify the
delta - ZDTM_DELTA. If it's unset (which is default behaviour in ZDTM) -
it would default to 5 seconds. However, if it's set (what we can do from
vzt-cpt) - then it will use delta which is set by our test.

A unix socket can be bound to itself, so we need only one socket
instead of a pair of pipe.
If we use a socket, we can peek a message and if it isn't for us
we don't need to send it back.
Currently a process reads message from pipe, if it isn't for him,
it sends it back and sleeps for a random timeout. In a worst case
each waiter will read and send a message back, before the right
one will get it.
