The new apple silicon processesors (m1/m2) are capable of using a performent apple
hypervisor (included in macos). Our "virtual providers" for podman
machine are part of an interface design. This PR provides an
implementation of the interface to begin the work for supporting the
apple hypervisor. It is basically only a skeletal PR.
The actual code for using the hypervisor and launching a machine will
come as several new PRs following the inclusion of this one.
There will likely be code reuse between the applehv and qemu code; but
none of that code is being moved at this time. It will be moved "on
demand" during development.

Before making / mutable/immutable, podman-machine checks if the mount is
being done in /home or /mnt. However the current check is always going
to be true:
```
!strings.HasPrefix(mount.Target, "/home") || !strings.HasPrefix(mount.Target, "/mnt")
```
is false when mount.Target starts with "/home" and mount.Target starts
with "/mnt", which cannot happen at the same time.
The correct check is:
```
!strings.HasPrefix(mount.Target, "/home") && !strings.HasPrefix(mount.Target, "/mnt")
```
which can also be written as:
```
!(strings.HasPrefix(mount.Target, "/home") || strings.HasPrefix(mount.Target, "/mnt"))
```
The impact is not too bad, it results in extra 'chattr -i' calls which
should be unneeded.

qemu fails when the same `fw_cfg` options is used more than once.
Since the current logic always adds a new option on each machine load
this will fail on the second start.
We can fix this by checking if the option is already set and replace but
I think it is easier to just not commit the option in the config and add
it dynamically on start. User that hit this bug have to recreate the
machine.

When trying to connect to the qemu ready socket we should check if the
qemu process is still running, if it is not we can just error out. There
is no point in retrying.
To do so we have to directly call wait with WNOHANG.
Also change StartProcess to os/exec package which is higher level and
allows us to use a buffer as qemu stderr fd.

This addresses:
Symlinks don't work on podman machine on macOS Monterey when using volumes feature #13784
This change does NOT exactly fix the bug, but it does allow the user to
work around it via 'podman init' option, e.g.:
podman machine init -v "$HOME/git:$HOME/git:ro:security_model=none"
If the default security model were to be changed to 'none', then that
would fix the bug, at the possible cost of breaking any use cases that
depend on 'mapped-xattr'.
The documentation of the purpose and behavior of the different security
models seems to be rather light:
https://wiki.qemu.org/Documentation/9psetup#Starting_the_Guest_directly
From testing, it appears that the mapped-xattr security model intends to
manage symlinks such that the guest can see the symlinks but the host
only sees regular files (with extended attributes). As far as I can
tell, this behavior only makes sense when the guest is the only thing
that ever needs to create and read symlinks. Otherwise, symlinks created
on the host are unusable on the guest, and vice versa.

Interrupting a `podman machine start` (ex: with CTRL-C) would leave
`Starting: true` in the machine's config file. Due to #14469 any

The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.

add three new config entries Starting (bool) Created (time) LastUp (time) to actually

When starting a VM that has been configured with volume mounts, the
podman client attempts to connect via TCP to localhost, which runs
gvproxy to proxy an ephemeral port to the VM's ssh port. Previously,
gvproxy was listening on all interfaces and IP addresses, but this
behavior has changed to listening only on the IPv4 loopback address.
Without this change, if a newer build of gvproxy is used, a podman
machine configured with volume mounts will hang forever after "podman
