* richcarl/eliminate_lib_module/PR-1786/OTP-15072:
  Fix minor issues
  Eliminate call to ct:get_progname() in ts_erl_config
  Use \n escape instead of integer 10
  Move error formatting to erl_error.erl and delete lib.erl
  Move extended parse functions in lib.erl to erl_eval.erl
  Move lib:eval_str/1 into mod_esi.erl
  Remove lib:progname/0
  Eliminate call to lib:progname/1 in slave.erl
  Add ct:get_progname/0
  Remove lib:error_message/2
  Remove lib:flush_receive/0
  Remove lib:send/2 and lib:sendw/2
  Move lib:nonl/1 into yecc.erl

by using a cooperative strategy that will make
any process accessing the table execute delelete_all_objects_continue
until the table is empty.

This is not an optimal solution as concurrent threads will still
block on the table lock, but at least thread progress is made.
