[CRIU] [PATCH cr 10/12] pipes: restore pipes data

[Andrey Vagin]

Restore all data in a one place.
Pipes data are saved in a file and they saved together with
a read tail, but they may be restored only with a write tail.

So we have to way:
* Find data in a file for each pipe
* Find pipe for each portion of data

Information about pipes are saved in memory, so I choose this way.
