I actually don't particular care if we keep them or not, except that if
we keep them, we need to give them a prefix.

We can either introduce an eieio-compat package full of defaliases, or
do what we did with cl/cl-lib and turn eieio.el into a deprecated compat
package (and introduce a new package eieio-lib to replace it).

No, it can be autoloaded, like the definitions in cl-macs, cl-seq, and
cl-extra get autoloaded.
