criu: Version 0.4 release

This is the first release, that actually doesn't require a custom
kernel in order to make all the tool features to work. Just take
the v3.8 (with proper config) and that's it :)

Another coolness about this release is the ARM port. In this case,
however, one does require a custom kernel, since the kcmp system
call is not wired into the ARM table in the upstream kernel :(

What else? Quite a lot, actually:

* C/R ability of a LOT of new stuff
* Remote syscall execution
* Deprecation of --namespace option
* Build system rework
* Ability to collect gcov info
