7d62e40f7e Switch from x/net/context -> context
Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".

Many vendored packages still use x/net/context, so vendor entry remains
for now.

7368e41c07 Docker pull/push with max concurrency limits.
This fix tries to address issues raised in #20936 and #22443
where `docker pull` or `docker push` fails because of the
concurrent connection failing.
Currently, the number of maximum concurrent connections is
controlled by `maxDownloadConcurrency` and `maxUploadConcurrency`
which are hardcoded to 3 and 5 respectively. Therefore, in
situations where network connections don't support multiple
downloads/uploads, failures may encounter for `docker push`
or `docker pull`.

This fix tries changes `maxDownloadConcurrency` and
`maxUploadConcurrency` to adjustable by passing
`--max-concurrent-uploads` and `--max-concurrent-downloads` to
`docker daemon` command.

The documentation related to docker daemon has been updated.

Additional test case have been added to cover the changes in this fix.

This fix fixes #20936. This fix fixes #22443.

5c99eebe81 Fix concurrent uploads that share layers
Concurrent uploads which share layers worked correctly as of #18353,
but unfortunately #18785 caused a regression. This PR removed the logic
that shares digests between different push sessions. This overlooked the
case where one session was waiting for another session to upload a
layer.

This commit adds back the ability to propagate this digest information,
using the distribution.Descriptor type because this is what is received
from stats and uploads, and also what is ultimately needed for building
the manifest.

Surprisingly, there was no test covering this case. This commit adds
one. It fails without the fix.

See recent comments on #9132.

f33fa1b8d3 Change push to use manifest builder
Currently this always uses the schema1 manifest builder. Later, it will
be changed to attempt schema2 first, and fall back when necessary.

572ce80230 Improved push and pull with upload manager and download manager
This commit adds a transfer manager which deduplicates and schedules
transfers, and also an upload manager and download manager that build on
top of the transfer manager to provide high-level interfaces for uploads
and downloads. The push and pull code is modified to use these building
blocks.

Some benefits of the changes:

- Simplification of push/pull code
- Pushes can upload layers concurrently
- Failed downloads and uploads are retried after backoff delays
- Cancellation is supported, but individual transfers will only be
  cancelled if all pushes or pulls using them are cancelled.
- The distribution code is decoupled from Docker Engine packages and API
  conventions (i.e. streamformatter), which will make it easier to split
  out.

This commit also includes unit tests for the new distribution/xfer
package. The tests cover 87.8% of the statements in the package.
