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.

qemu need the id to start with a letter for some reason.
If this is not the case qemu will fail:
```
qemu-system-x86_64: -device virtserialport,chardev=ad053e0bb519f_ready,name=org.fedoraproject.port.0: Property 'virtserialport.chardev' can't find value 'ad053e0bb519f_ready'
er
Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.

To fix this we just add an "a" in front of it.

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.

Also document existing ro and rw options.
Also remove misleading statement about /mnt. By my observation, this
line is incorrect. If the intended meaning is different, then I don't
understand.
The default volume is mounted read/write and is not within /mnt.

Connecting with `podman machine ssh` can results in the following

Best would probably be to remove `LC_ALL` (and other locale and lang
env vars) from `/etc/ssh/sshd_config.d/50-redhat.conf` in the CoreOS
image, but I'm not terribly sure how, so this is a quick alternative.

- New `VMPidFilePath` field in MachineVM config holds the path for the
qemu PID file
- qemu is now started with the `-pidfile` argument set to `VMPidFilePath`
- Machines created before this won't have the VM PID file configured,
stopping these VMs will revert back to waiting on the state to change
away from `Running`, plus an added 2s sleep to give time for the VM to
exit and to avoid potential issues
- Machines created after this will have a VM PID file configured and
stopping the machine will wait indefinitely for the VM to exit

This PR covers two edge cases discovered by fiddling with machine
manually. It is possible (like after a manual cleanup of a machine)
that a leftover qemu socket file can indicate the prescense of a machine
running.
Also, reveal the error of a Exec.Command by wrapping the generic error
around what was in stderr.

Interrupting a `podman machine start` (ex: with CTRL-C) would leave
`Starting: true` in the machine's config file. Due to #14469 any
subsequent starts would fail since Podman would think the machine is
still in the process of starting.
Fixed here by listening for the interrupt signal and setting `Starting:
false` in the event.

This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

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.
This should help maintainability.

podman machine was using the file modification time to get the running status
add three new config entries Starting (bool) Created (time) LastUp (time) to actually
keep track of when these events happened. This means we can use the config file
to actually store this data and not mess up the created/last-up time.
This fixes the issues where the machine would report running 15 seconds before it was up.
Also fixes the issue of modifying the file manually and saying the machine is "up"
