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.
The rl_startup_hook function has different prototype in libreadline and
in the libedit.
To fix this issue, arguments of hook function has been wrapped to C
preprocessor macro and properly adjusted.
