To test migration through the file descriptor we should build and provide
a path to socket_scm_helper file. This way is inconvenient for acceptance
testing.
This series provides new functions to receive and send messages over a UNIX
socket. And adds a new migration test.

Oksana Vohchana (3):
  Adding functions _send_fds and _recv_fds
  Updates send_fd_scm function
  Acceptance test: FD migration
