sage.functions is the home for symbolic functions; this package will not be included in the distribution package sagemath-standard-no-symbolics (#32601), nor in smaller distributions such as sagemath-polyhedra (#32432).

sage.functions.log.log is not a symbolic function but only wrapper def that either delegates to a symbolic function or calls a method. We move it to sage.misc.functional so that non-symbolic uses of it do not pull in symbolics; and change these imports.

There is already a function log in sage.misc.functional, deprecated since #19444 (Sage 8.1). We replace it.

We keep a non-deprecated import of log in sage.functions.log for symbolic uses.

Similar to what was done in #32717 for sqrt.
