In GetDefaultDevices(), make sure MachineConfig has an AppleHypervisor
instance before attempting to access it. This fixes a SIGSEGV when
running with libkrun as machine provider.

wait for the healthy status on the thread where the container lock is
held. Otherwise, if it is performed from a go routine, a different
thread is used (since the runtime.LockOSThread() call doesn't have any
effect), causing pthread_mutex_unlock() to fail with EPERM.

The function that's handing us events will return an error after closing
the channel over which it's sending events, and its caller (in its own
goroutine) will then send that error over another channel.
The logic that started the goroutine is likely to notice that the events
channel is closed before noticing that the error channel has a result
for it to read, so any error that would have been communicated would be
lost.
When we finish reading events, check if the reader returned an error
before telling our caller that there was no error.

Under some circumstances podman might be executed with a different argv0
than the actual path to the podman binary. This breaks the reexec logic
as it tried to exec argv0 which failed.
This is visible when using podmansh as login shell which get's the
special -podmansh on argv0 to signal the shell it is a login shell.
To fix this we can simply use /proc/self/exe as command path which is
much more robust and the argv array is still passed correctly.

Adds provider detection for LibKrun in `pkg/provider/platform_darwin.go`.
Changes the macOS version check to 13 instead of 11, and now uses the `semver`
package to verify current version.

commit b3014c1c69 changed
GetRootlessRuntimeDir() to return an empty string for root, so that
its value is not exported as XDG_RUNTIME_DIR, and other programs like
crun can use a better default.
Now GetRootlessPauseProcessPidPath() uses homedir.GetRuntimeDir().
The homedir.GetRuntimeDir() function returns a value also when running
as root so it can be used inside a nested Podman.

Some programs have their configuration files relative to the user's
home. It would be convenient being able to mount these into the container, but
that requires expansion of `~` or `$HOME` in a label. This commit adds support
for that for the `runlabel` command.

AppleHV accepts a max 36 bytes for mount tags. Instead of using the fully qualified path for the mount tag, SHA256 the path, and truncate the shasum to 36 bytes.
Also correctly escape dashes in mounted paths.

Cache cleanups only happen if there is a cache miss, and we need to pull a new image
For quay.io/podman/machine-os, we remove all old images from the cache dir. This means we will delete any file that exists in the cache dir; this should be safe to do since the machine pull code should be the only thing touching this cache dir. OCI machine images will always have a different manifest, and won’t be updated with the same manifest, so if the version moves on, there isn’t a reason to keep the old version in the cache, it really doesn’t change.
For Fedora (WSL), we use the cache, so we go through the cache dir and remove any old cached images, on a cache miss. We also switch to using ~/.local/share/containers/podman/machine/wsl/cache as the cache dir rather than ~/.local/share/containers/podman/machine/wsl. Both these behaviors existed in v4.9, but are now added back into 5.x.
For generic files pulled from a URL or a non-default OCI image, we shouldn’t actually cache, so we delete the pulled file immediately after creating a machine image. This restores the behavior from v4.9.
For generic files from a local path, the original file will never be cleaned up
Unsure how to test, so:
[NO NEW TESTS NEEDED]

This PR adds libkrun support to podman machine. This is an experimental feature and should not be marketed yet. Before we unmark the experimental status on this function, we will need to have full CI support and a full podman point release has pased.
This work relies on the fact that vfkit and libkrun share a reasonably (if not perfectly) same API. The --log-level debug option will not show a GUI screen for boots as krun is not capable of this.

Effectively, this is an ability to take an image already pulled
to the system, and automatically mount it into one or more
containers defined in Kubernetes YAML accepted by `podman play`.
Requirements:
- The image must already exist in storage.
- The image must have at least 1 volume directive.
- The path given by the volume directive will be mounted from the
image into the container. For example, an image with a volume
at `/test/test_dir` will have `/test/test_dir` in the image
mounted to `/test/test_dir` in the container.
- Multiple images can be specified. If multiple images have a
volume at a specific path, the last image specified trumps.
- The images are always mounted read-only.
- Images to mount are defined in the annotation
"io.podman.annotations.kube.image.automount/$ctrname" as a
semicolon-separated list. They are mounted into a single
container in the pod, not the whole pod.
As we're using a nonstandard annotation, this is Podman only, any
Kubernetes install will just ignore this.
Underneath, this compiles down to an image volume
(`podman run --mount type=image,...`) with subpaths to specify
what bits we want to mount into the container.

Image volumes (the `--mount type=image,...` kind, not the
`podman volume create --driver image ...` kind - it's strange
that we have two) are needed for our automount scheme, but the
request is that we mount only specific subpaths from the image
into the container. To do that, we need image volume subpath
support. Not that difficult code-wise, mostly just plumbing.
Also, add support to the CLI; not strictly necessary, but it
doesn't hurt anything and will make testing easier.

This is something Docker does, and we did not do until now. Most
difficult/annoying part was the REST API, where I did not really
want to modify the struct being sent, so I made the new restart
policy parameters query parameters instead.
Testing was also a bit annoying, because testing restart policy
always is.

The Docker endpoint here is kind of a nightmare - accepts a full
Resources block, including a large number of scary things like
devices. But it only documents (and seems to use) a small subset
of those. This implements support for that subset. We can always
extend things to implement more later if we have a need.
