[CRIU] [RFC 0/3] compel: Ship std_ string helpers

[Cyrill Gorcunov]

NOT FOR MERGING!

Hi guys, while using volatile in https://github.com/xemul/criu/issues/279
for a fix I think we still might go further and simply drop off all
builtin_ helpers but rather provide ones in std_ compel module.
The work is still incompelete 'cause need to look intp powerpc
versions of asm-optimized helpers. But just to present you
some preliminary results. The idea is to use std_memset/memcpy
explicitly where needed.

Cyrill Gorcunov (3):
  compel: Move string helpers in STD subplugin
  criu: Use std_ helpers from compel library for builtins
  criu: Drop builtin_ helpers
