Solomon Hykes c6f0a70141 Move utilities and interfaces out of `inmem` 
* `utils.Buffer`: a Sender which stores messages in a slice
* `utils.Copy`: beam equivalent of `io.Copy`
* `utlis.NopSender`: a Sender which silently discards messages
* `utlis.NopReceiver`: a Receiver which always returns EOF

Solomon Hykes b9c316df29 inmem: complete Copy implementation 
Copy can now handle arbitrary nesting of streams, without knowing the
underlying type of either the source or destination.

It does this by attempting `SendTo` and `ReceiveFrom`, then if that is
not supported, falling back to nested copies in separate goroutines.

Solomon Hykes 12b5459a1c inmem.StackSender: a dynamic beam forwarded with health checks 
StackSender forwards beam messages to a dynamic list of backend receivers.
New backends are stacked on top. When a message is sent, each backend is
tried until one succeeds. Any failing backends encountered along the way
are removed from the queue.

Solomon Hykes 2c9e18009f Fix stdin handling in engine.Sender and engine.Receiver 
This introduces a superficial change to the Beam API:

* `beam.SendPipe` is renamed to the more accurate `beam.SendRPipe`
* `beam.SendWPipe` is introduced as a mirror to `SendRPipe`

There is no other change in the beam API.

Alexander Larsson e9651077fc beam: Add simple framing system for UnixConn 
This is needed for Send/Recieve to correctly handle borders between
the messages.

The framing uses a single 32bit uint32 length for each frame, of which
the high bit is used to indicate whether the message contains a file
descriptor or not. This is enough to separate out each message sent
and to decide to which message each file descriptors belongs, even
though multiple Sends may be coalesced into a single read, and/or one
Send can be split into multiple writes.

Alexander Larsson faa83a0fc0 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.
