[CRIU] [PATCH 19/26] pipes: Add c/r for fifo files

[Cyrill Gorcunov]

Basically pipes are superset over fifos,
so we integrate fifo c/r into pipes.c.

There os acatually a trick used to open fifo files --
since fifo may block on opening we create a fake fifo
to be able to proceed without sleeping.
