docs/devel: more documentation on the use of suffixes
Using _qemu is a little confusing. Let's use _compat for these sorts of things. We should also mention _impl which is another common suffix in the code base.

lock held, the function that expects the lock to be already held
usually uses the suffix ``_locked``.
+If a function is a shim designed to deal with compatibility
+workarounds we use the suffix ``_compat``. These are generally not
+called directly and aliased to the plain function name via the
+pre-processor. Another common suffix is ``_impl``; it is used for the
