Onboard: Add onboard virtual keyboard

[pratheekshasn]

Summary of Changes

The PR adds the virtual keyboard "Onboard" to meta-openembedded.

Justification

#AB2491688 requires the keyboard to be present on scarthgap as well.

The virtual keyboard "Onboard" (present on kirkstone) had been removed from scarthgap due to build errors on python 3.12. This PR adds back the same with corrections required for python3.12.

Implementation

Changes that differ from kirkstone:

1. The recipe inherits setuptools3 instead of distutils3. This change is required since distutils3 has been deprecated in python3.12 and the compile step fails. Since the compile fails, there are no packages that get installed.
2. The recipe also installs the autostart file that gets generated at the staged folder's python site-packages folder to /etc/xdg/autostart folder. This is necessary because of the first change. setuptools3 installs files to the site-packages folder no matter what absolute path is specified as the prefix for the installation path.
3. There is a new patch file that is now added to the recipe: onboard_hover_seg_fault.patch. This patch was found online here.
   Currently, when the mouse pointer hovers on a key, the app crashes with a segmentation fault, and this is what the patch fixes.

Other required changes can be seen in this PR in the meta-nilrt layer.

The keyboard can now be launched and used just like in kirkstone.

Testing

• I have built the core package feed with this PR in place. (bitbake packagefeed-ni-core)

Tested by installing the built IPK on a VM.

• Keyboard launch
• Type on keyboard by clicking on the keys
• Click on other windows (like the file explorer) to test that the keyboard goes to the background
• Click on any window or textbox where something can be typed to test that the keyboard is back in focus and can type

Have y'all discussed upstreaming this? If we cannot convince meta-OE upstream to revive the recipe, then we should instead move everything into meta-nilrt.

Changes look fine.

But since we'd like to submit this upstream first, mentioning scarthgap in commit message is not ideal as we'd be submitting to master branch. So something like Onboard: Add onboard virtual keyboard would be better.

Once this ends up in upstream, we can do upstream merge to get the change into our repo.

Before sending upstream, please test it in poky and make sure the recipe is usable on its own i.e., it builds, produces valid package which is installable and usable without any NI specific changes from the meta-nilrt layer.

This is not accurate, please fix.

Refer https://docs.yoctoproject.org/contributor-guide/recipe-style-guide.html#patch-upstream-status - I think it can be classified as "Inactive-Upstream", and the reason to [lastcommit: when (and/or) lastrelease: when].

I know we mention Not Submitted as one of the reasons in https://github.com/ni/meta-nilrt/blob/nilrt/master/next/docs/styleguide.md#L133 but haven't found mention of it upstream.

[pratheekshasn]

I have fixed this now.

[chaitu236]

Looks good. Can be sent upstream now.
