The libreadline starting from version 6 is licensed as GPLv3. For some
use cases it is not acceptable to use this license.

In the NetworkManager the libreadline is used by nmcli.
This change allows using libedit instead of libreadline.

Following adjustments were made:
1. The history_set_history_state() is not supported in the libedit.
   Instead, the where_history() with remove_history() were used to remove
   the history content if needed.

2. rl_complete_with_tilde_expansion - it is the binary flag used only
   when one wants to have the expansion support. The libedit is not
   supporting and hence exporting this flag.
