[CRIU] [PATCH 2/9] vdso: Introduce vdso pie-engine

[Cyrill Gorcunov]

It's quite minimal at moment and provides only two helpers

 - vdso_redirect_calls, to patch vdso area redirectling
   calls to some new place.

 - vdso_fill_symtable, to parse vma area as vdso library
   and fill symbols table with offsets and names.

Because these routines will be needed in both regular criu
code and restorer code -- we compile it in pie format.
