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.
