pkg/urlutil (despite its poorly chosen name) is not really intended as a generic
utility to handle URLs, and should only be used by the builder to handle (remote)
build contexts.
- IsURL() only does a very rudimentary check for http(s):// prefixes, without any
other validation, but due to its name may give incorrect expectations.
- IsGitURL() is written specifically with docker build remote git contexts in
mind, and has handling for backward-compatibility, where strings that are
not URLs, but start with "github.com/" are accepted.
Because of the above, this patch:
- moves the package inside builder/remotecontext, close to where it's intended
to be used (ideally this would be part of build/remotecontext itself, but this
package imports many other dependencies, which would introduce those as extra
dependencies in the CLI).
- deprecates pkg/urlutil, but adds aliases as there are some external consumers.

Commit 6ca3ec88ae deprecated the experimental
"--stream" option for the legacy builder, adding an error message is a client
attempted to use this feature.
However, the detection used the session-ID (`session=xxx` query parameter),
which happens to be set automatically by the CLI if it detects that the daemon
has session support. Because of this, builds fail when trying to perform them
on a daemon with the `--experimental` flag set.
This patch changes the detection to look for the `remote` query parameter, which
is set to "client-session" when using the `--stream` option with the classic
(non-Buildkit) builder.
Before this change, running `docker build` with an older (19.03 or older) cli
against a daemon with `--experimental` enabled caused an error:
$ dockerd --experimental &
$ docker pull docker:18.09
$ docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock docker:18.09 sh -c 'echo "FROM scratch" | docker build -'

With this patch, the error only occurs when trying to use the experimental
`--stream` option:
$ dockerd --experimental &
$ docker pull docker:18.09
$ docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock docker:18.09 sh -c 'echo "FROM scratch" | docker build -'

Errors should not be capitalized. This error was marked as
"being compatible" with the old error, However, looking at
the original error that was in place before d1faf3df27,
I noticed that the error was lowercase before, so it should
be ok to change it back to be lowercase.

By 0296797f0f, `progressReader`
and `remoteURL` were removed from arguments. So developers who
use `Detect` not need to care about when `ProgressReaderFunc`
is used.

The test was passing previously because the preamble was already buffered. After
the change to return Scanner.Err() the final read error on the buffer was no
longer being ignored.

This enables docker cp and ADD/COPY docker build support for LCOW.
Originally, the graphdriver.Get() interface returned a local path
to the container root filesystem. This does not work for LCOW, so
the Get() method now returns an interface that LCOW implements to
support copying to and from the container.
