Add NULL checks from master
The big "don't check for NULL" cleanup requires backporting some of the lowest-level functions to actually do nothing if NULL is given. This will make it easier to backport fixes to release branches, where master assumes those lower-level functions are "safe" This commit addresses those tickets: 3798 3799 3801.
