I posted v5 where I added _dl_audit_premap_dlmem
audit extension for dlmem. It allows (with the demo
test-case) to feed an fd to dlmem().
Obviously you can't do anything like this with the
APIs that already have or use an fd.

Note: this isn't the only extension that I need.
I just wanted to add them later. But to demonstrate
you the advantage of dlmem(), I had to add one
of them directly to v5.
