 1.12  19-Dec-2021  riastradh amdgpu: amdgpu_dma_buf.c
 1.11  19-Dec-2021  riastradh drm: Another pass over i915 and some supporting logic.

This makes a shim around sg_table, which essentially represents two
things:

1. an array of pages (roughly corresponding to bus_dma_segment_t[])
2. an array of DMA addresses stored in a bus_dmamap_t

Both parts are optional; different parts of i915 use sg_tables to
pass around one or both of the two parts. This helps to reduce the
ifdefs by quite a bit, although it's not always clear which part of
an sg_table any particular interface is actually using which is why I
was reluctant to do this before.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")
