Currenty a parent can go far away from child and we will need to wait
too long for checking results.
This pach limits delta to [MIN_DELTA, 2 * MIN_DELTA].
Thi patch should fix current errors for the CRIU-iter job in Jenkins.

ARCH is a user-facing variable and setting it on the command line
clobbers any manipulation attempted in the makefile. Following
the example of the Linux kernel makefiles, use a SRCARCH variable
instead for the internal, potentially fixed-up, architecture name.
This fixes the following error.
make ARCH=x86_64
Makefile:69: *** "The architecture x86_64 isn't supported". Stop.

When a process is started in a new pid namespace, the init process must
colleck zombies.
But before this the init process must waits the root test process, which
returns a status of preparation stage.
Currently these two operation can race, because the both ones call waitpid().

This test does a few operation in a loop
* create a mapping with random flags
* touch a few pages in a new mapping, if it's writable
This test has two processes. The second process goes a predefined value
of steps behind the first one. When we need to check the result, we stop
the first process, wait until the second process come to the same point
and compare these processes. The processes are dumped in different
states, but at the end both processes must be in the same state.

To people using vim, I'd suggest adding the following code to ~/.vimrc:
let c_space_errors = 1
highlight FormatError ctermbg=darkred guibg=darkred
match FormatError /\s\+$\|\ \+\t\|\%80v.\|\ \{8\}/

Here are client, server programs and two libraries for dumping client
sockets and syslog socket.
The client can ask server to save a value and then request it later.
We suppose that after dumping and restoring the client will get
the same value.
So the dump callback requests the value and save it in a file.
The restore callback creates a new socket and ask server to save the
value from the file.
v2: open a syslog socket
