This fix tries to fix issues encountered when running a container with a hostname
that is longer than HOST_NAME_MAX(64).
Previously, `could not synchronise with container process` was generated as the
length of the regex check was missing.
This fix covers the length check so that a hostname that is longer than
HOST_NAME_MAX(64) will be given a correct error message.
Several unit tests cases and additional integration test cases are added as well.
This fix closes#21445.

Instead of implementing refcounts at each graphdriver, implement this in
the layer package which is what the engine actually interacts with now.
This means interacting directly with the graphdriver is no longer
explicitly safe with regard to Get/Put calls being refcounted.
In addition, with the containerd, layers may still be mounted after
a daemon restart since we will no longer explicitly kill containers when
we shutdown or startup engine.
Because of this ref counts would need to be repopulated.

This fix tries to fix Docker core dumps when removing network with special
characters. The issue is from the fact that when docker client tries to
pass the command to API, the networkID is not escaped in case of special
characters. This also means other commands (not just `docker network rm`)
may face the same issue (e.g., `docker network connect`).
This fix adds the URL path escape to properly handle it. In addition, an
integration test for network create and delete is added to cover the cases
in #21401.
This fix fixes#21401.

This allows a user to specify explicitly to enable
automatic copying of data from the container path to the volume path.
This does not change the default behavior of automatically copying, but
does allow a user to disable it at runtime.

This adds support for the passthrough on build, push, login, and search.
Revamp the integration test to cover these cases and make it more
robust.
Use backticks instead of quoted strings for backslash-heavy string
contstands.

This cleans up some of the use of the filepoller which makes reading
significantly more robust and gives fewer changes to fallback to the
polling based watcher.
In a lot of cases, if the file was being rotated while we were adding it
to the watcher, it would return an error that the file doesn't exist and
would fallback.
In some cases this fallback could be triggered multiple times even if we
were already on the fallback/poll-based watcher.
It also fixes an open file leak caused by not closing files properly on
rotate, as well as not closing files that were read via the `tail`
function until after the log reader is completed.
Prior to the above changes, it was relatively simple to cause the log
reader to error out by having quick rotations, for example:
```
$ docker run --name test --log-opt max-size=10b --log-opt max-files=10
-d busybox sh -c 'while true; do usleep 500000; echo hello; done'
$ docker logs -f test
```
After these changes I can run this forever without error.
Another fix removes 2 `os.Stat` calls when rotating files. The stat
calls are not needed since we are just calling `os.Rename` anyway, which
will in turn also just produce the same error that `Stat` would.
These `Stat` calls were also quite expensive.
Removing these stat calls also seemed to resolve an issue causing slow
memory growth on the daemon.

The issue comes from the implementation of volumeSplitN() where a
driver letter (`[a-zA-Z]:`) was assumed to follow either `:`, `/`,
or `\\`.
In Windows driver letter appears in two situations:
a. `^[a-zA-Z]:` (A colon followed by `^[a-zA-Z]:` is OK as colon is
the separator in volume option)
b. A string in the format like `\\?\C:\Windows\...` (UNC).
Therefore, a driver letter can only follow either a `:` or `\\`
This PR removes the condition of `/` before the driver letter so
that options like `-v /tmp/q:/foo` could be handled correctly. A
couple of tests has also been added.
This PR fixes#20122.

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 fix addressed the issue of test TestRestartStoppedContainer
in #21211. Inside the test, a `docker restart` command is
followed by a `docker logs` command. However, `docker restart`
returns immediately so there is no guarantee that `docker logs`
will wait until the restarted container completes the command
`echo foobar`.
This fix use the check of `{{.State.Running}} = false` to make
sure that the restarted container has already finished, before
invoking the `docker logs` command. The timeout is set to 20s
to make sure it passes WindowsTP4 check.
This fixes#21211.
