Fix one minor issue with vfkit error handling. First checking if err !=
nil OR errors.Is() is pointless as the err != is already true.
Second nilerr complains because we return nil when we hit an error
branch, in this case this is correct because an error means VM is
stopped.

It qemu cannot be compiled anyway so make sure we do not try to compile
parts where the typechecker complains about on windows.
Also all the e2e test files are only used on linux as well.
pkg/machine/wsl also reports some error but to many for me to fix them
now. One minor problem was fixed in pkg/machine/machine_windows.go.

By enabling UserKnownHostsFile=/dev/null, and CheckHostIP=no
options to the defaults we prevent the user from adding the host key
multiple times and from flakes that can raise Remote Host Id change.

When removing the gvproxy pid file, under CI conditions we could hit a
case where the PID file being removed seemed to have an open handle on
it still. I could not find anything in podman that left an open handle
and gvproxy would have quit before this, so we think it is likely
another process holding it. I could not find root cause with CI because
I could not trip the flake.
this new code allows windows (specifically hyperv bc WSL does not use
GVProxy) to ignore an ERROR_SHARING_VIOLATION.

This adds generic utility to convert file system path into URL structure.
Instead of string manipulation it uses URL parsing and building routines.
Appending absolute path to `unix:///` URL out of the box correctly
handles URL format on Windows platform, where filepath should be prepended
by additional `/` before drive letter.

When the file is empty it is possible our code panics as bar.ProxyReader
returns nil when the bar is finished which is the case for 0 size as it
doesn't have to read anything from there. However as this happens on
different goroutines it is race and most of the time still works.
To fix this simply skip the progress bar setup for empty files.
While at it fix the deprecated argument in the tests.

In case of timeouts actually log the command again and make sure to send
SIGABRT to the process as go will create a useful stack strace where we
can see where things are hanging. It also kill the process unlike the
default Eventually().Should(Exit()) call the leaves the process around.
The output will be captured by default in the log so we just see the
stack trace there.
And while at it bump the timout up to 10 mins, we are hitting hard
flakes in CI where machine init takes longer than 5 mins for unknown
reasons but this seems to be good enough.

Currently all podman machine rm errors in AfterEach were ignored.
This means some leaked and caused issues later on, see #22844.
To fix it first rework the logic to only remove machines when needed at
the place were they are created using DeferCleanup(), however
DeferCleanup() does not work well together with AfterEach() as it always
run AfterEach() before DeferCleanup(). As AfterEach() deletes the dir
the podman machine rm call can not be done afterwards.
As such migrate all cleanup to use DeferCleanup() and while I have to
touch this fix the code to remove the per file duplciation and define
the setup/cleanup once in the global scope.

On linux and macos the connections are stored under the home dir by
default so it is not a problem there but on windows we first check
the APPDATA env and use this dir as config storage. This has the problem
that it is not cleaned up after each test as such connections might leak
into the following test causing failues there.

One problem on FCOS is that the root directory is immutable, as such in
order to mount arbitrary paths from the host we must make it mutable
again and create these dir on boot in order to be able to mount there.
The current logic was racy as it used one unit for each path and they
all did chattr -i /; mkdir -p $path; chattr -i / and systemd can run
these units in parallel. That means it was possible for another unit to
make / immutable before the unit could do the mkdir. I pointed this out
on the original PR[1] but we never followed up on it...
Now this here changes several things. First have one unit that does the
chattr -i / (immutable-root-off.service), it is hooked into
remote-fs-pre.target which means it is executed before the network
mounts (virtiofs) are done.
Then we have another unit that does chattr +i /
(immutable-root-on.service) which turn the immutable root back on after
remote-fs.target which means all mount are done at this point.
Additionally the automount unit is removed because it does not add any
value for us and it was borken anyway as it used the virtiofs tag as
path so systemd just ignored it.

The current timeout was not long enough. Systemd default is 90s so we
should wait for at least that long. Also it really doesn't make sense to
throw an error we saying we failed waiting for stop. We should hard
terminate the VM in case a graceful shutdown did not happen.

Stop copying the pre-pulled uncompressed machine disk into the individual test dir. The machine pull code already makes a copy of the disk into the test's HOMEDIR/.local/share/containers/podman/machine, and works off that copy.
Before the change: TESTDIR/<image> is copied to TESTDIR/podman_test/<image> by the test, and then podman machine copies the image to TESTDIR/podman_test/.local/share/containers/podman/machine/provider/<image>
After the change: TESTDIR/<image> is copied to TESTDIR/podman_test/.local/share/containers/podman/machine/provider/<image> by podman machine
The image that is actually run is at TESTDIR/podman_test/.local/share/containers/podman/machine/provider/<image> in both instances.

We do a soft stop via systemd to allow graceful shutdown behavior.

Regardless of the CI issue we should always to the hard terminate in

First of some commands ignored cmd.Wait() error which means it was
impossible to notice any command errors. And others only returned
the wait error as it which when a command fails is just
`exit status <code>` which is not helpful at all.

2. Reduce bitwise operations to improve code maintainability

I'm hitting a bug with 9p when trying to transfer large files.
In RHEL at least 9p isn't supported because it's known to have a
lot of design flaws; virtiofsd is the supported and recommended
way to share files between a host and guest.
Add a new hidden `PODMAN_MACHINE_VIRTFS` environment
variable that can be set to `virtiofs` to switch to virtiofsd.

When running with "log-level=debug" and libkrun as machine provider,
spawn a Terminal to execute "krunkit" to enable users to have full
access to the VMs console for debugging purposes.
Users obtain an interactive, text console with scrollback. It's possible
to interact with both the kernel and GRUB2. To obtain even additional
debugging information, users can add "console=hvc0" to the linux kernel
command line through GRUB2 (it may be worth considering extending the
initial configuration of the VM to add that argument by default).
