cd911b83ce beam: Fix double close of fds in SendUnix
Instead of calling syscall.Close() on the fds in sendUnix() we call
Close() on the *os.File in Send(). Otherwise the fd will be closed, but
the *os.File will continue to live, and when it is finalized the
fd will be closed (which by then may be reused and can be anything).

This also adds a note to Send() the the file is closed.

5220dbeffd beam/examples/beamsh: commands are messages.
Commands in the pipeline should either implement or pass-through command messages.

This amounts to a proof-of-concept implementation of the "pipeline"
design of Docker plugins.

071e5e5a65 beam: Make extracted Fds CloseOnExec
Grab forklock to make sure no forks accidentally inherit the new fds
before they are made CLOEXEC There is a slight race condition between
ReadMsgUnix returns and when we grap the lock, so this is not
perfect. Unfortunately There is no way to pass MSG_CMSG_CLOEXEC to
recvmsg() nor any way to implement non-blocking i/o in go, so this is
hard to fix.
