[CRIU] [PATCH 0/9] pie/util-vdso refactoring

[Dmitry Safonov]

This should come as a part of compat patches set, but as
I have saw vdso_fill_symtable I couldn't refrain from
refactoring that.

The first patch may be yet not needed, but as all following
patches were based on it, I send with it.
The second is not only about dropping undefined behavior, but
also made code more readable from my point of view.
The fith patch adds checking that we can dereference structure
from pointer from Elf header (before it checked that
the pointer lay in needed memory region, but not pointer's
structure member addresses).
The last three patches are mere cleanups.

The patches set was tested with Travis, but as criu-dev
is broken now, build for ARM/Aarch64 failed:
https://travis-ci.org/0x7f454c46/criu/builds/119550125
Anyway, it was tested on the top of compatible patches
set and the build for ARM/Aarch64 succeed:
