drm/doc: Document drm_file.[hc]
Well, mostly drm_file.h, and clean up all related things:
- I didnt' figure out the difference between preclose and postclose.
The existing explanation in drm-internals.rst didn't convince me,
since it's also really outdated - we clean up pending DRM events in
the core nowadays. I put a FIXME in for the future.
- Another FIXME is to have a macro for default fops.
- Lots of links all around, main areas are to tie the overview in
drm_file.c more into the callbacks in struct drm_device, and the
other is to link render/primary node code to the right sections in
drm-uapi.rst.
- Also moved the open/close stuff to drm_drv.h from drm-internals.rst,
seems like the better place for that information. Since that section
was rather outdated this amounted to full-on rewrite.
A big missing piece here is some overview graph, but I think better to
wait with that one until drm_device and drm_driver are also fully
documented.
