Fixes `docker system prune --filter until=<timestamp>`.
`docker system prune` claims to support "until" filter for timestamps,
but it doesn't work because builder "until" filter only supports
duration.
Use the same filter parsing logic and then convert the timestamp to a
relative "keep-duration" supported by buildkit.

- Only use the image exporter in build if we don't use containerd
Without this "docker build" fails with:
Error response from daemon: exporter "image" could not be found
- let buildx know we support containerd snapshotter
- Pass the current snapshotter to the buildkit worker
If buildkit uses a different snapshotter we can't list the images any
more because we can't find the snapshot.
builder/builder-next: make ContainerdWorker a minimal wrapper
Note that this makes "Worker" a public field, so technically one could
overwrite it.
builder-next: reenable runc executor
Currently, without special CNI config the builder would
only create host network containers that is a security issue.
Using runc directly instead of shim is faster as well
as builder doesn’t need anything from shim. The overhead
of setting up network sandbox is much slower of course.
builder/builder-next: simplify options handling
Trying to simplify the logic;
- Use an early return if multiple outputs are provided
- Only construct the list of tags if we're using an image (or moby) exporter
- Combine some logic for snapshotter and non-snapshotter handling
Create a constant for the moby exporter
Pass a context when creating a router
The context has a 10 seconds timeout which should be more than enough to
get the answer from containerd.

This utility wasn't very related to all other utilities in pkg/ioutils.
Moving it to longpath to also make it more clear what it does.
It looks like there's only a single (public) external consumer of this
utility, and only used in a test, and it's not 100% clear if it was
intentional to use our package, of if it was a case of "I actually meant
`io/ioutil.MkdirTemp`" so we could consider skipping the alias.
While moving the package, I also renamed `TempDir` to `MkdirTemp`, which
is the signature it matches in "os" from stdlib.

Setting cmd.Env overrides the default of passing through the parent

The OCI image spec is considering to change the Image struct and embedding the
Platform type (see opencontainers/image-spec#959) in the go implementation.
Moby currently uses some struct-literals to propagate the platform fields,
which will break once those changes in the OCI spec are merged.
Ideally (once that change arrives) we would update the code to set the Platform
information as a whole, instead of assigning related fields individually, but
in some cases in the code, image platform information is only partially set
(for example, OSVersion and OSFeatures are not preserved in all cases). This
may be on purpose, so needs to be reviewed.
This patch keeps the current behavior (assigning only specific fields), but
removes the use of struct-literals to make the code compatible with the
upcoming changes in the image-spec module.

The fillGo18FileTypeBits func was added in 1a451d9a7b
to keep the tar headers consistent with headers created with go1.8 and older.
go1.8 and older incorrectly preserved all file-mode bits, including file-type,
instead of stripping those bits and only preserving the _permission_ bits, as
defined in;
- the GNU tar spec: https://www.gnu.org/software/tar/manual/html_node/Standard.html
- and POSIX: http://pubs.opengroup.org/onlinepubs/009695399/basedefs/tar.h.html
We decided at the time to copy the "wrong" behavior to prevent a cache-bust and
to keep the archives identical, however:
- It's not matching the standards, which causes differences between our tar
implementation and the standard tar implementations, as well as implementations
in other languages, such as Python (see docker/compose#883).
- BuildKit does not implement this hack.
- We don't _need_ this extra information (as it's already preserved in the
type header; https://pkg.go.dev/archive/tar#pkg-constants
In short; let's remove this hack.

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.

Finish the refactor which was partially completed with commit
34536c498d, passing around IdentityMapping structs instead of pairs of
[]IDMap slices.
Existing code which uses []IDMap relies on zero-valued fields to be
valid, empty mappings. So in order to successfully finish the
refactoring without introducing bugs, their replacement therefore also
needs to have a useful zero value which represents an empty mapping.
Change IdentityMapping to be a pass-by-value type so that there are no
nil pointers to worry about.
The functionality provided by the deprecated NewIDMappingsFromMaps
function is required by unit tests to to construct arbitrary
IdentityMapping values. And the daemon will always need to access the
mappings to pass them to the Linux kernel. Accommodate these use cases
by exporting the struct fields instead. BuildKit currently depends on
the UIDs and GIDs methods so we cannot get rid of them yet.

This removes some of the checks that were added in 0cba7740d4,
but should no longer be needed.
- `dockerfile.BuildFromConfig()` is used for `docker (container) commmit` and
`docker (image) import`. For `docker import`, we're failing early already.
For `commit`, it won't be possible to have a container that doesn't have the
right operating-system, so there's no need to validate.
- `dispatchRequest.getImageOrStage()`: simplify the check; all checks resulted
in an error on Windows, so it came down to "Windows does not support FROM scratch".
- `dispatchState.beginStage()`: `image.OperatingSystem()` already defaults to the
`runtime.GOOS` if unset, so remove the local default fallback.

This argument was added for LCOW support, but it was only used to verify if
the passed platform (OS) matched the host. Given that all uses of this function
(except for one) passed runtime.GOOS, we may as well move the check to that
location.
We should do more cleaning up after this, and perform such validations early,
instead of passing platform around in too many places where it's only used for
similar validations. This is a first step in that direction.
