This patch adds a new --tls-verify flag to the `podman machine init`
sub command which matches many of our other commands. This allows the
user to optionally control whether TLS verification is enabled or
disabled for download of the machine image.
The default remains to leave the TLS verification decision to the
backend library which defaults to enabling it, this patch just
allows the user to explicitly set it on the CLI.
Fixes: #26517

this patch changes how the detection of wsl works.
The old way of using wsl --status command output to detect some missing features required by WSL is not fully reliable.
WSL checks if the wsl feature is enabled and if the vmcompute service do exist. However, this is not enough to identify if the virtual machine platform feature is enabled. The vmcompute service could exist because it has been installed by other tools or it could exist but being stopped.
The way proposed by this patch is to try execute the import command and,
if it fails, check the error and if it is related to the Host Compute
Service try to install all features required by WSL.
The flow is the same as before, the user is asked to execute the podman
machine init command with elevated privileges. Eventually, after
enabling WSL and VMP features, the user is asked to reboot the machine.
When the machine restarts, the powershell gets invoked again and execute
the command init.
The code also fixes some issues that could cause misbehaviors when
invoking recursively the elevated shell, like an unreleased lock, or a
missing file.

Add `--swap` argument to `podman machine init` command.
Passing an int64 value to this flag will trigger the Podman machine
ignition file to be generated with a zram-generator.conf file containing
the --swap value as the zram-size argument.
This file is read by the zram-generator systemd service on boot
resulting in a zram swap device being created.

When certain directories, like /tmp, get mounted over, FCOS/Linux can
act in unexpected ways. Added a sanity check for a list of directories
think might be impacted by this. Also, moved the volume parsing earlier
in the init process so we can catch problems before the expensive
decompression of machine images.
The following destinations are forbidden for volumes:
`/bin`, `/boot`, `/dev`, `/etc`, `/home`, `/proc`, `/root`, `/run`, `/sbin`, `/sys`, `/tmp`, `/usr`, and `/var`. Subdirectories

As issue #25112 points out, it was possible to start a machine on one of the darwin providers and then switch providers and start another one with a different name. This PR firstly prevents that use which is a forbidden use case.
Secondarily, performed some minor cleanup on the error messages being used so that the error would be specific to this condition.
This bug fix is for darwin only. In the case of Windows, we probably need to answer the question I raised in #24067 first, which is whether we want to stop allowing WSL to run multiple machines.

We need to take another lock to prevent concurrent starts from different
machines.
I manually tested it by starting three VM in parallel with:
podman machine start & podman machine start test1 & podman machine start test2
I also added a CI test that seems to work as expected (failed with the
old binary, worked with the new)
Before this patch I was able to start more than VM, with this patch it
now only starts one of them and the other ones will fail to start with
a proper error.

Currently we first read the conf and then lock, this is racy because
while we wait for the lock another process might change the state so

First make sure we check that a given VM exist when holding the VM lock
for it. The check in cmd/podman/machine/init.go is a nice quick out but
not enough to ensure that 2 processes to not create the same VM at the

checking if the VM config file exists.

Make sure we only update the machine config when we are locked.
While it doesn't make a functional differnce for cpu and memory it was a
problem for disk size. The disk size must be larger than the previous
one so we must have accurate data on the previous value.
Thus change the settings only while locked and refresh the config so we
have the current up to date values.

Previously, the locks were on the provider layer, which doesn't make a vm operation with a config file update atomic. Move them up a layer, so the entire function locks while doing provider and config operations.
This adds a Remove and a Set function to the shim layer.

When gvproxy exits it will delete the pidfile itself so we need to
account for that and juts ignore the case, it just means gvproxy was
able to exit successfully on its own.
Also remove the useless defer and return the error so we can get an
error exit code not just a print on stderr.
Currently it shows this error which is not helpful to any user:
unable to clean up gvproxy: "unable to read gvproxy pid file /run/user/1000/podman/gvproxy.pid: open /run/user/1000/podman/gvproxy.pid: no such file or directory"

Copy all proxy envs into the VM on each start, this allows for updates
without having to recrate the VM. This is implemented via shell script
that is passed via ssh to the VM after it is started.
With that we now use the same logic for all providers the old fw_cfg
logic for qemu has been removed and the WSL code as well which keeps the
behavior the same.
There is a small risk now because we only update the env via ssh that
processes started before will have the old incorrect env but it should
really only effect core system processes which likely do not need them
anyway. The podman system service should not be started at this point
so it should be good enough.
It also fixes the broken behavior with SSL_CERT_FILE/SSL_CERT_DIR which
were updated on each start which is not correct as the files are only
copied with ignition so these should not be updated and just set
statically when the VM was created.
e2e test has been added to ensure the behavior works as expected.

Podman machine reset is a new command that will "reset" your podman
machine environment. Reset is defined as:
* Stop and Remove all VMs
* Remove the following directories:
- configuration dir i.e. ~/.config/containers/podman/machine/qemu
- data dir i.e. ~/.local/.share/containers/podman/machine/qemu
When deleting, if errors are encountered, they will be batched and spit
out at the end. Podman will try to proceed even in error in doing what
it was told.

this pr represents a shift in how we download podman machine images.
these images will now be stored in oci registry and will replace the
default method of downloading an image. you can still use a reference
to a disk image as a path or url too with the --image-path switch.
the final registry and location of the images has not been determined;
and will need to be updated in podman as well.
i dont think we need to allow --image-path to accept a registry/image
for the podman 5.0 release. i do think there will be demand for this.
upgrades also need to be plumbed. for example, updating from an oci
registry.
once we make decisions on final image locations/registrties as well as
some behaviors of init and the oci pull, we must update the machine-init
documentation.

we should not panic podman when it has to deal with a podman4 machine
config. instead, we throw a soft error for `machine ls` and in all
other cases, we throw a hard error stating that the machine config is
incompatible.
a future PR will provide instructions on how to recover from this.
current idea is something like `podman machine reset` which blows
everything away machine-wise.
