This is a refresh of the user-only patch set from March.
I do not attempt to implement any part of a kernel abi wrt mmap
and/or mprotect. Instead, it uses a x-tagged-pages property to
assume that all anonymous pages have tags.
The tests added are disabled by default, but do pass if you have
binutils 2.32 installed.

I'm going to skip reviewing this until we have a defined
kernel ABI to compare against.
