Log message:
Add a new so_seek member to "struct file" such that we can have seekable
files that aren't vnodes. Move the vnode-specific code into its own
function. Add an implementation for the "DMA buffers" that can be used
by DRI3/prime code to find out the size of the graphics buffer.
This implementation is very limited and only supports offset 0 and only
for SEEK_SET and SEEK_END. This doesn't really make sense; implementing
stat(2) would be a more obvious choice. But this is what Linux does.
ok guenther@, visa@
