* ext/readline/extconf.rb: checked to have clear_history in

readline library.
* ext/readline/readline.c (hist_get, hist_each, Init_readline): 
  The offset specified for the argument of history_get() might be
  different in GNU Readline and libedit. If use libedit, it was
  corrected that the computational method of the offset specified
  for the argument of history_get() when the Readline module was
  initialized was decided.
  (hist_get, hist_set): If use libedit, accesses first an input
  content in history when specifies the negative offset for the
  argument of history_get() or replace_history_entry(). Then
  checks the offset is negative in ruby.
  (rb_remove_history): When compiling, it corrects it to warning
  when libedit is used.
  (hist_clear, Init_readline): added Readline::HISTORY.clear
  method. [ruby-dev:35551]
* test/readline/test_readline_history.rb: added unit test for
  Readline::HISTORY.
