Custom roboRIO HAL: Where to find C library for roboRIO fpga?

Those C bindings are for a different FPGA image running on the roboRIO. That API and that FPGA are designed to closely mimic the myRIO counterparts. This will certainly be updated in future years (it was only released yesterday!). However, I don't believe it is what you are looking for.

I found you!

There is a higher level presentation floating around the Internet that I wrote years ago. As for registers, WPILib is the most accurate documentation.

This way I can access libNiFpga directly instead of having to go through the roborio-specific frontend. I was able to get some rudimentary parsing done with a crappy python script.

That's actually what I would recommend. Except not manually parsed. Use the NiFpga API for accessing registers. That's all the ChipObject does.
