Revamp the integration test to cover these cases and make it more
robust.

Changes how the Engine interacts with Registry servers on image pull.
Previously, Engine sent a User-Agent string to the Registry server
that included only the Engine's version information. This commit
appends to that string the fields from the User-Agent sent by the
client (e.g., Compose) of the Engine. This allows Registry server
operators to understand what tools are actually generating pulls on
their registries.

This test was checking that it received every progress update that was
produced. But delivery of these intermediate progress updates is not
guaranteed. A new update can overwrite the previous one if the previous
one hasn't been sent to the channel yet.
The call to t.Fatalf exited the current goroutine which was consuming
the channel, which caused a deadlock and eventual test timeout rather
than a proper failure message.
Failure seen here:

The download manager assumed there was at least one layer involved in
all images. This can be false if the image is essentially a copy of
`scratch`.
Fix a nil pointer dereference that happened in this case. Add
integration tests that involve schema1 and schema2 manifests.

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.

Attempt layer mounts from up to 3 source repositories, possibly
falling back to a standard blob upload for cross repository pushes.
Addresses compatiblity issues with token servers which do not grant
multiple repository scopes, resulting in an authentication failure for
layer mounts, which would otherwise cause the push to terminate with an
error.

This allows easier URL handling in code that uses APIEndpoint.
If we continued to store the URL unparsed, it would require redundant
parsing whenver we want to extract information from it. Also, parsing
the URL earlier should give improve validation.

With the --insecure-registry daemon option (or talking to a registry on
a local IP), the daemon will first try TLS, and then try plaintext if
something goes wrong with the push or pull. It doesn't make sense to try
plaintext if a HTTP request went through while using TLS. This commit
changes the logic to keep track of host/port combinations where a TLS
attempt managed to do at least one HTTP request (whether the response
code indicated success or not). If the host/port responded to a HTTP
using TLS, we won't try to make plaintext HTTP requests to it.
This will result in better error messages, which sometimes ended up
showing the result of the plaintext attempt, like this:
Error response from daemon: Get
http://myregistrydomain.com:5000/v2/: malformed HTTP response
"\x15\x03\x01\x00\x02\x02"

Several improvements to error handling:
- Introduce ImageConfigPullError type, wrapping errors related to
downloading the image configuration blob in schema2. This allows for a
more descriptive error message to be seen by the end user.
- Change some logrus.Debugf calls that display errors to logrus.Errorf.
Add log lines in the push/pull fallback cases to make sure the errors
leading to the fallback are shown.
- Move error-related types and functions which are only used by the
distribution package out of the registry package.

This reverts commit 84b2162c1a.
The intent of this commit was to set an idle timeout on a HTTP
connection. If a read took more than 60 seconds to complete, or a write
took more than 60 seconds to complete, the connection would be
considered dead.
This doesn't work properly, because the HTTP internals apparently read
from the connection concurrently while writing. An upload that doesn't
complete in 60 seconds leads to a timeout.

`Upload` already closes the reader returned by `compress` and the
progressreader passed into it, before returning. But even so, the
io.Copy inside compress' goroutine needs to attempt a read from the
progressreader to notice that it's closed, and this read has a side
effect of outputting a progress message. If this happens after `Upload`
returns, it can result in a write to a closed channel. Change `compress`
to return a channel that allows the caller to wait for its goroutine to
finish before freeing any resources connected to the reader that was
passed to it.

A watcher would output the current progress item when it was detached,
in case it missed that item earlier, which would leave the user seeing
some intermediate step of the operation. This commit changes it to only
output it on detach if it didn't already output the same item.

Currently, the temporary file storing downloaded layer data is only
removed after a successful download or a digest verification error. A
transport-level error does not cause it to be removed. This is a
regression from 1.9 that could cause disk usage to grow until the Docker
daemon is restarted.

Things could go wrong if Watch was called after the last existing
watcher was released. The call to Watch would succeed even though it was
not really adding a watcher, and the corresponding call to Release would
close hasWatchers a second time.
The fix for this is twofold:
1. We allow transfers to gain new watchers after the watcher count has
touched zero. This means that the channel returned by Released should
not be closed until all watchers have been released AND the transfer is
no longer tracked by the transfer manager, meaning it won't be possible
for additional calls to Watch to race with closing the channel returned
by Released.
The Transfer interface has a new method called Close so the transfer can
know when the transfer manager no longer references it.
Remove the Cancel method. It's not used and should not be exported.
2. Even though (1) makes it possible to add watchers after all the
previous watchers have been released, we want to avoid doing this in
practice. A transfer that has had all its watchers released is in the
process of being cancelled, and attaching to one of these will never be
the correct behavior. Add a check if a watcher is attaching to a
cancelled transfer. In this case, wait for the transfer to be removed
from the map and try again. This will ensure correct behavior when a
watcher tries to attach during the race window.
Either (1) or (2) should be sufficient to fix the race involved here,
but the combination is the most correct approach. (1) fixes the
low-level plumbing to be resilient to the race condition, and (2) avoids
using it in a racy way.
