Having the device node last makes it easy for us to test the same line
on various devices. That is not the most common use-case - normally we'd
expect our users to have one mouse and run several commands on it
(that's the case during debugging as well).
So let's change the device node to be the first argument, it makes for
easier typing/copy-paste, etc.
Plus it makes it a lot more obvious which one the full command is
(`dpi set 800` in this example)
```
$ ratbagctl hidraw4 dpi set 800
```

The SVGs must not be part of any stable API, there is too much behavior
implied that we cannot/do not specify. So it's perfectly likely that a future
change in the SVGs or rendering libraries breaks things in some detail. But
then we cannot update the SVGs without risking breaking other clients that
rely on the current behavior.
Besides: we only have one theme, called "gnome" because a push
towards having SVGs for other themes never happened.
And that theme isn't gnome-specific, it merely looks GNOMEy. The theme is very
much piper-specific in that it requires certain elements that piper cares
about. Currently anyway, if we make this part of our API, piper cannot change
that behavior ever without breaking others.
So let's drop SVG handling completely and rely on the clients to sort it out
for themselves.
For now the SVGs are left in the tree to make it easier to copy to Piper. Once
that's done, we will remove those too.

When the SVGs need to be maintained elsewhere, we need something reliable to
match devices with SVGs. The easiest is to provide a unique model string,
usually composed from the usb/bluetooth information.
A string format was chosen to make it more flexible for the glorious future
where we have something other than usb or bluetooth devices. Meanwhile, the
format is the well-known "usb:1234:56ef:0" string (bus, vid, pid, version).
The version in this string is a future-proof safeguard for libratbag. It will
be used where libratbag supports two devices with the same VID/PID and where
this is not otherwise differentiable. We don't have any such devices yet, so
libratbag just returns a hardcoded 0.
The format is currently defined for usb and bluetooth, in the future we may
have other strings.
The base guarantee is that this is a reliable identifier for the model that
will never change for that model. IOW this is what piper can use to map
devices to their SVGs.

The led type was the physical led type to describe where the LED sits.
This property is basically unused and of questionable use anyway. GUI
applications would need to rely on drawings of the mouse anyway. Scripts don't
really care because ratbagctl uses the led index anyway. The only time this
matters is when we're looking at (human) device discovery. But even then just
trying to set the LED is enough to figure out which one is which.
So let's drop this API on the assumption that it's not really needed and
maintaining and extending that enum forever is not necessary.
This is not a full purge, merely the DBus API that gets dropped.

We started with event nodes for some reason lost in the distant past (probably
because that's what a lot of other tools use). But since we exclusively deal
with hidraw devices here and event nodes only serve to look up the hidraw
node, let's get rid of that indirection layer and work with hidraw directly.
Note that changes how ratbagctl works, it used the event nodes before. So
anyone who hardcoded the event node in one way or another is going to see
breakage. Then again, the "eventX" string was the device ID as advertised by
ratbagd, so it's supposed to be treated as an opaque string anyway.

Strings on DBus need to be valid UTF8, some of the default profile names on
the G700 include the degree character (" Profile n° 1"), the whole string ends
up being invalid UTF8.
This results in two issues:
- ratbagd gets quietly kicked off the bus when it sends that string
- ratbag-command throws an exception because Python is unhappy about the
non-UTF8 string:
UnicodeEncodeError: 'utf-8' codec can't encode character '\udcb0' in position 3: surrogates not allowed
The quick workaround here is to strip anything that's not ASCII from the
profile name. The same may be necessary for some device names too, but let's
wait until we see that.
For ratbag-command we convert the string to bytes and back using the 'ignore'
argument, this way we should see the original profile string without the
printf errors.
This is an incomplete fix, we'll have the same issue if a user tries to set a
non-ASCII name. The long-term fix is to convert whatever we have (probably ISO
8859-1, but can we detect that?) into UTF8 before passing it around. That
would also mean converting it back before writing to the device.

This isn't used by anything in the tree and Piper doesn't use it either.
(`ratbagctl` queries it from the sodipodi name in the SVG).
Plus, assuming we run sandboxed the filename is useless anyway, `GetSvgFd()`
takes care of this bit though.

* tools: canonicalize path first in udev_device_from_path
This fixes a problem in which running ratbag-command with the path to a
device node symlink (e.g. /dev/logi-g502 -> /dev/input/event4), such as
one created by a udev rule, would not work correctly, due to the code
failing to resolve the symlink prior to checking for the presence of the
"/dev/input/event" prefix.
This resulted in nonsensical error messages (shown below) and the
curious inability to run ratbag-command successfully with anything but
the actual raw path to the device node itself (e.g. /dev/input/event4
would work fine, but /dev/logi-g502 would not, despite both being valid
ways of getting to the same device node).
Error: Can't open '/dev/logi-g502': Success
Error: Device '/dev/logi-g502' is not supported
Note that this same problem also prevented the usage of autogenerated
symlinks by udev, i.e. '/dev/input/by-id/' and '/dev/input/by-path/'.

If we're sandboxing the client we don't have access to the SVG files directly.
So pass a read-only file descriptor to the client over DBus and let them deal
with the SVG that way.
In ratbagd.py we pull the fd off but we convert the quirky dbus error into a
normal FileNotFoundError(), much easier to catch in the caller.
On the ratbagctl side we now have to search the SVG for it's name - stored in
the 'sodipodi:docname' attribute by Inkspace. This isn't guaranteed to exist
or be always correct, but meh, it's close enough. We could continue to use the
GetSvg() call here but I want to deprecate that and remove it in the near
future.

In some cases we get Piper trying to use None as a list, see
https://github.com/libratbag/piper/issues/237
This can be reproduced by returning an error (e.g. -ENOMEM) from
ratbagd_get_devices(). That error isn't handled anywhere on the client side,
the effective result is that the property is None when calling
proxy.get_cached_property().
The error is visible on the bus:
method call time=1535084121.223284 sender=:1.1311 -> destination=:1.1310
serial=7 path=/org/freedesktop/ratbag1;
interface=org.freedesktop.DBus.Properties; member=GetAll
string "org.freedesktop.ratbag1.Manager"
error time=1535084121.223433 sender=:1.1310 -> destination=:1.1311
error_name=org.freedesktop.DBus.Error.NoMemory reply_serial=7
string "Cannot allocate memory"
Make ratbagd.py more robust here and always return an empty list for those
properties where we expect an array. This papers over the real bug which is
that a) we need better logging in ratbagd on errors and b) something on the
other side needs to handle this error.

clang analyzer doesn't know how to handle __attribute__(cleanup()).
There are only 2 warnings raised because the analyzer only look at the

2 are detected by clang and then marked as memory leak.
