For exec and attach use an upgrade request which the server responds
with HTTP 101 status. Since go 1.12 the Body can be casted to an
io.Writer and then use that to write to the server.
This does however not allow us to skip the ugly hack of overwriting
the default dialContext() because the ReadWriterCloser on the body
does not allow us to call CloseWrite() which is critical to correctly
close the stdin side. So we still have to extract the underlying
net.Conn for that.
Using the cast response.Body is important because the underlying http
lib reads from the socket to parse the header and response code of
course and it is possible that it read more content than needed that is
kept in its buffer but because we then only directly read from the
connection it was possible we miss the first few bytes of the message.
This should fix the issue and hopefully also some long standing
podman-remote missing output flakes in CI.

Add support for loading images directly from machine paths to avoid
unnecessary file transfers when the image archive is already accessible
on the running machine through mounted directories.
Changes include:
- New /libpod/local/images/load API endpoint for direct machine loading
- Machine detection and path mapping functionality
- Fallback in tunnel mode to try optimized loading first
This optimization significantly speeds up image loading operations
when working with remote Podman machines by eliminating redundant
file transfers for already-accessible image archives.

Prior to this commit `artifact remove --all` was not supported on remote
clients.
This patch adds a new artifact API endpoint `artifact/remove` which can
either take a list of artifacts to remove or remove all artifacts by
setting all=true.
This patch removes the temporary warning message in the tunnel interface
implementation of ArtifactRm if `--all` was passed on the command line
and uses the new `artifact/remove` endpoint.
This patch also updates the `artifact remove` command both remote and
local to accept a list of artifacts to remove rather than limiting to
just one.

Fixed the --build-context flag to properly send files for remote builds. Previously
only the main context was sent over as a tar while additional contexts were passed as
local paths and this would cause builds to fail since the files wouldn't exist.
New changes modifies the Build API to use multipart HTTP requests allowing multiple
build contexts to be used. Each additional context is packaged and
transferred based on its type:
- Local Directories: Sent as tar archives
- Git Repositories: link sent to the server where its then cloned
- Container Images: Image reference sent to the server, it then pulls the image there
- URLs/archives: URL sent to the server, which handles the download

Do not ignore ErrUnexpectedEOF from DemuxHeader(), if we fail to parse
the header there must have been a clear protocal error between client
and server which should be reported and not silently ignored. I wonder
ig this might explain why we have missing remote exec/attach output
without any error, it is possible we are eating some internal errors due
this.
Commit ba8eba83ef added the ErrUnexpectedEOF check but without any
explanation why that would be needed. The tests from that commit pass
without it locally but not in CI. With some debugging best I found the
issue is actually a test bug. The channel is not consumed until it is
closed which means the main test exists before the log reading goroutine
is done. And if the main test exists the first step it does is to kill
the podman service which then can trigger the ErrUnexpectedEOF server on
the still open http connection and thus the test case failed there.

Deadcode should that the ShouldRestart() API endpoint was never wired
into the router so the endpoint did not existed and the bindings called
a non existing endpoint which returnd 404 which the binding code
assumed means no restart.
As such remove all this code as it didn't do anything useful. And IMO
exposing a shouldrestart API always feeled wrong to me. The client
should not have to deal with this.
This commit does not change the behavior but it also does not make an
attempt to fix the broken restart handling with the rmeote client. Given
we do not seem to have any user reports about this it seems it is not
used.

As with `volume export`, this was coded up exclusively in cmd/
instead of in libpod. Move it into Libpod, add a REST endpoint,
add bindings, and now everything talks using the ContainerEngine
wiring.
Also similar to `volume export` this also makes things work much
better with volumes that require mounting - we can now guarantee
they're actually mounted, instead of just hoping.
Includes some refactoring of `volume export` as well, to simplify
its implementation and ensure both Import and Export work with
readers/writers, as opposed to just files.
Fixes#26409

Previously, our approach was to inspect the volume, grab its
mountpoint, and tar that up, all in the CLI code. There's no
reason why that has to be in the CLI - if we move it into
Libpod, and add a REST endpoint to stream the tar, we can
enable it for the remote client as well.
As a bonus, previously, we could not properly handle volumes that
needed to be mounted. Now, we can mount the volume if necessary,
and as such export works with more types of volumes, including
volume drivers.

In the case of an Decoder error which is not EOF we loop forever, as the
Decoder stores some errors each next Decode() call will keep returning
the same error. Thus we loop forever until we run out of memory as each
error was stored in pullErrors array as described in [1].
Note this does not actually fix whatever causes the underlying
connection error in the issue, it just fixes the loop/memory leak.

The --env is used to add new environment variable to container or
override the existing one. The --unsetenv is used to remove
the environment variable.
It is done by sharing "env" and "unsetenv" flags between both
"update" and "create" commands and later handling these flags
in the "update" command handler.
The list of environment variables to add/remove is stored
in newly added variables in the ContainerUpdateOptions.
The Container.Update API call is refactored to take
the ContainerUpdateOptions as an input to limit the number of its
arguments.
The Env and UnsetEnv lists are later handled using the envLib
package and the Container is updated.
The remote API is also extended to handle Env and EnvUnset.

A lot of types are moved and now deprecated which causes lint issues.
IDResponse is copied into podman because that has no new 1 to 1
replacement. For some fields that we set as part of the docker API I
added the nolint directive as these fields might be used by API
consumers.
For the other types it is mostly a 1 to 1 move.
ParseUintList is deprecated but we can use the same function from
github.com/containers/storage/pkg/parsers instead.
Note that it containers breaking changes to pkg/bindings which we should
not do generally but given the prevoius commit already has a unavoidable
breaking change we might as well fix the IDResponse issue once now.
