* In a previous update in 2021 many copyright ranges were truncated
accidentally, and some files have been copy-pasted with wrong years. These
dates have been fixed based on git history and original copyright messages.
* We need to check for map writes even if the mapped buffer isn't the one that's
referenced by a submit but still overlaps it. We do this by moving to the heap
for all placed resources so any map to a buffer on a heap is checked as long
as any buffer bound to that heap is referenced.
