Create a development image

[zehnm]

For developing low level functions for the YIO-Remote it's best to run the application on the same environment as the final release. Issues pop up much earlier and it's easier to debug the cause.

Goals:

• [x] Base the image on the develop branch
  • Whenever possible only add additional tools
  • Libraries must remain in the same version, otherwise the develop branch must be upgraded as well
• Add required tools for Qt remote interactions:
  • [x] rsync
  • [ ] sftp
  • [ ] gdb server for remote debugging
• [x] Add wpa-supplicant configuration file template in boot partition
• [x] Add config.txt & cmdline.txt templates for HDMI output in boot partition
• Add support for additional hardware
  • [x] Device overlays and drivers for Pimorony's HyperPixel 3.5 screen
  • [ ] Device overlays and drivers for Pimorony's HyperPixel 4.0 screen
• [ ] Detailed logging
• [x] Optional: add USB support to Kernel
  • [ ] Optional: USB gadget drivers for serial console and network

I've started refactoring the project structure in branch refactor-buildroot-project to simplify developer configurations and regular RPi builds.

Regular RPi Zero-W and RPi 3 boards with HDMI and USB touch screens are now supported in the master branch:

• build.sh rpi0w
• build.sh rpi3
