In order to implement the gem export callback, we need a type to represent
struct dma_buf. So - this commit introduces a set of stub bindings for
dma_buf. These bindings provide a ref-counted DmaBuf object, but don't
currently implement any functionality for using the DmaBuf.

JFYI - After talking a bit to the Asahi folks, it seems like that we're
actually a ways off from Asahi having any actual usecase for the export()
callback - so I'm going to just drop the dma_buf bits here for the next
version of the patch series

Agh! Sorry for the spam, I should have double checked the code before writing
this as I realized the reason I didn't implement this. Correct me if I'm wrong
here since it's the first time I've interacted very much with this API in the
kernel but: it seems like the reference counting for dma_buf obj
…though, I just realized immediately after sending that response to you that I
mentioned that this type is reference counted in the commit message - but I
never actually added an implementation for AlwaysRefCounted. So, that's at
least one additional thing I will make sure to add. Similarly though,
