[issue8065] Memory leak in readline.get_current_history_length

[Mark Dickinson]

I've fixed this leak in r83670 through r83672.  It's still using the old, inefficient method (get the state, read the length, free the state), because without good tests I don't want to disturb things too much.  In particular, it's not clear whether libedit keeps the history_length variable properly updated.

There are still the remaining issues of:

 - better testing for the readline module, and
 - attempting to work around libedit bugs.

Perhaps those should become separate issues, though?
