[CRIU] [PATCH 06/11] util-net: Itroduce send_fds/recv_fds routines

[Cyrill Gorcunov]

We will need these helpers to transfer file
descriptors from dumpee to our space.

Also make send_fd/recv_fd to be a wrappers over
send_fds/revc_fds to not duplicate the code.

Note the return code -2 is dropped from recv_x
routines, it is never analyzed anyway.
