Use obarray functions from obarray.

* lisp/abbrev.el (copy-abbrev-table, abbrev-table-p, make-abbrev-table,
  abbrev-table-get, abbrev-table-put, abbrev-table-empty-p,
  clear-abbrev-table, define-abbrev, abbrev--symbol, abbrev-table-menu):
  delegate to obarray.el functions.
* lisp/loadup.el: load obarray before abbrev
* test/automated/abbrev-tests.el: new tests
