The current invocation doesn't work:
$ busybox dc "100" "5" / p
dc: can't open '100': No such file or directory
Fix it so that it does:
$ busybox dc -e "100 5 / p"

One of the messages that is printed on failure was missing
the "WARNING:" prefix. Address that too.

Soon openrc-settingsd (hostnamed) will uses these properties so the
information can be exposed to apps like GNOME Settings.
Let's also move the shellcheck comment to the outer scope, otherwise
we'd need four of these comments now, and let's not use ${} but just $.
Allow calling the script with:
SPLASH_CONFIG=$srcdir/splash.ini devicepkg_build $startdir $pkgname
In order to pass a custom splash config, as it will be used with the
PineNote (MR 2910).
We need to generate the splash screens separately for each device,
because they are specific to the device's display resolution.
At the moment we do this dynamically during the installation process.
This has the advantage that there is no need to re-build all device
packages when one of the splash screen is changed (or a new one is added).
In reality, however, the splash screens do not change very frequently.
On the other hand, generating the splash screens dynamically has signficant
disk usage overhead for a minimal ("none" UI) rootfs:
The Python interpreter together with the necessary libraries requires
about ~60 MB of disk space on aarch64.
The splash screens itself require about ~100 KB for 720x1280.
This is not necessary if we move the splash screen generation into
devicepkg-dev, which is used to build the device package for all devices.
Another advantage is that we no longer need the (rather complicated)
caching mechanism for splash screens - so we actually end up with less
lines than before.
rootfs size for samsung-a5ulte ("none" UI):
Before: 450M
After: 388M (-62M)
After this change, every(!) device package needs to be rebuilt once.
No changes are necessary in device packages.
* Automatically generate a calibration matrix for libinput
This takes the calibration matrix for wayland and divides the pixel
offsets by the device width/height.
* Bump pkgrels of devices using devicepkg-dev
This causes new packages to be generated, using the new devicepkg-dev
version.
