BTRFS uses own device numbering scheme so lets do a trick
close one to what we have in CRIU itself -- mangle
device to match mountinfo output.

This test checks that the OverlayFS fixup for CRIU works correctly
by dumping and restoring a process that has an open file in an
OverlayFS mounted directory. This should work no matter if the
Kernel has the OverlayFS bug or not.

In test_msg() a buffer is allocated on stack to cook the outputed message.
This buffer's size was defined using the PAGE_SIZE constant defined in
zdtmtst.h file.
On some system like ppc64, the page size is large (64K), leading to massive
stack allocation, which may be too large in case of alternate stack like
the one used in the sigaltstack test.
This fix, defines a 2048 characters buffer for test_msg, and expose a
constant to allocate stack accordingly in the sigaltstack test.

Calls to setsockopt(PACKET_RX_RING/PACKET_TX_RING) are dependent of the

Using sysconf() page size makes these tests working on ppc64 where page

Since the page size may be different from an architecture/a system to
another it should not be hard coded to 4096.
As a consequence, several tests are failing on ppc64 due to a wrong page
size value.
This fix belongs to sysconf to get the current page size.

linux/seccomp.h may not be available, and the seccomp mode might not be
listed in /proc/pid/status, so let's not assume those two things are
present.
v2: add a seccomp.h with all the constants we use from linux/seccomp.h
v3: don't do a compile time check for PTRACE_O_SUSPEND_SECCOMP, just let
ptrace return EINVAL for it; also add a checkskip to skip the
seccomp_strict test if PTRACE_O_SUSPEND_SECCOMP or linux/seccomp.h
aren't present.
v4: use criu check --feature instead of checkskip to check whether the
kernel supports seccomp_suspend
