The memory in question is allocated and then remaped into
restorer with one call to mremap. Thus, to use the mem we
need to provide to users API for

* alloc memory
* get current allocation pointer
* convert current pointer into remapped one
* the remap itself

This would help combinding lots of small allocations such
as tcp sockets to unrepair, siginfos and posix timers.

Before doing something with mounts they should be marked as private,

If a parent mount point is shared with exteranl mntns, a child will be
umounted from the external mntns too.

For example:
$ mount -t tmpfs xxx /root/tmp/
$ mount --make-shared tmp
$ mkdir tmp/xxx
$ mount -t tmpfs xxx /root/tmp/xxx
$ touch tmp/xxx/a

$ unshare -m umount tmp/xxx
$ ls -l tmp/xxx/a
ls: cannot access tmp/xxx/a: No such file or directory

This patch changes a parent mnt to private for umounting childrens.

v2: exit if a mount point can not be marked ad private

This release goes on increasing the bugfix-to-features
ratio. Though we still have a lot of new stuff in the tool
the amount of bugs we've caught and fixed increases.

As a very notable feature it's worth mentioning that we
have prepared crtools to be ready to restore images,
converted from those generated by rh6-openvz kernel, i.e.
we are very close to have live-migration from rh6 to
whatever-it-will-be as the next openvz kernel.

1st stage is -- creating the timers. It may fail if kernel
allocated IDs in a manner we don't expect or runs out of
memory.

2nd stage is -- arm the timers. It cannot fail, since we've
validated the timespecs in advance and should happen after
we've waited for all the other tasks to complete the restore.

All timers are stopped during cpt/rst. We don't know in which moment
they are stopped and run, so this timeout is added to acceptable
