Subject: [Bug c/20318] New: RFE: add attribute to specify that a function never returns NULL

It would be useful to have a function attribute which specifies that the
function never returns NULL.

Currently the GCC 4 snapshots with -O2 -Wall generate ~15 spurious warnings in
the Subversion source code which could be eliminated if a couple of functions
could be marked as never returning NULL.
