Make `fset` and `defalias` signal an error on attempts to create circular alias chains. This is more effective, efficient and convenient than permitting alias loops to be created and trying to detect them at run time each time a function is called, which is what we have been doing until now, badly. * lisp/help-fns.el (help-fns--analyze-function): Don't pass obsolete argument. * lisp/subr.el (function-alias-p): * src/data.c (indirect_function, Findirect_function): Simplify. Now error-free, second argument obsolete. (Ffset): Detect loops. * test/lisp/help-fns-tests.el (help-fns--analyze-function-recursive): * test/lisp/subr-tests.el (test-alias-p): Adapt tests. * test/src/data-tests.el (data-tests-fset, data-tests-defalias): New. * doc/lispref/eval.texi (Function Indirection): * doc/lispref/functions.texi (Defining Functions, Function Cells): Update manual. * etc/NEWS: Announce.
