In case criu check is run as non-root, a lot of information is printed
to a user, with the only missing bit is it should run it as root.
Fix it.
I still don't like the fact that some other stuff is printed here,
like the timestamp and the __FILE__:__LINE__, but this should be
fixed separately.

Move prctl constants into own header. They are
arch independent.
The x86 specific ARCH_SET_GS should be fetched from <asm/prctl.h>
(instead of defining own ones).

This patch adds check for "/proc/sys/kernel/sem_next_id" to make sure, that
kernel supports restore of IPC objects.

This types specifies a strict set of what is hidden behind
the fd. Thus these numbers should be in the description of
the fdinfo message.
Plus protobuf makes shure nothing else will be there.

This serves two things -- kills annoying data offset management
which makes protobuf switch too ugly. And removes the need to
seek the pipe data image, which in turn is the prerequisity for
streaming migration.
Memory usage is still optimal, since we still use splice on dump
path and on restore stage we F_GIFT pipe buffers to the kernel.

To reflect the change in kernel v3.4-rc4
update PR_GET_TID_ADDR and rename it to
PR_GET_TID_ADDRESS as it named in kernel.

The ability to set PR_SET_MM_AUXV is implemented
in kernel as a separate PR_SET_MM extension, so
we need to test if the kernel patch is applied
on a running system.
