Also, use the channel to determine if the broadcaster is closed,
removing the redundant isClosed variable.

Before, this only waited for the download to complete. There was no
guarantee that the layer had been registered in the graph and was ready
use. This is especially problematic with v2 pulls, which wait for all
downloads before extracting layers.
Change Broadcaster to allow an error value to be propagated from Close
to the waiters.
Make the wait stop when the extraction is finished, rather than just the
download.
This also fixes v2 layer downloads to prefix the pool key with "layer:"
instead of "img:". "img:" is the wrong prefix, because this is what v1
uses for entire images. A v1 pull waiting for one of these operations to
finish would only wait for that particular layer, not all its
dependencies.

Allow to set the signal to stop a container in `docker run`:
- Use `--stop-signal` with docker-run to set the default signal the container will use to exit.

Without this change, there was a narrow race condition that would allow
writers to finish when there was still data left to write. This is
likely to be what was causing some integration tests to fail with
truncated pull output.

Calling runtime.Stack requires the buffer to be big enough to fit the
goroutines dump. If it's not big enough the dump will be truncated and
the value returned will be the same size as the buffer.
The code was changed to handle this situation and try again with a
bigger buffer. Each time the dump doesn't fit in the buffer its size is
doubled.

- Rename to Broadcaster
- Document exported types
- Change Wait function to just wait. Writing a message to the writer and
adding the writer to the observers list are now handled by separate
function calls.
- Avoid importing logrus (the condition where it was used should never
happen, anyway).
- Make writes non-blocking

The practice of buffering to a tempfile during a pushing contributes massively
to slow V2 push performance perception. The protocol was actually designed to
avoid precalculation, supporting cut-through data push. This means we can
assemble the layer, calculate its digest and push to the remote endpoint, all
at the same time.
This should increase performance massively on systems with slow disks or IO
bottlenecks.
