Makes sense in order for the user to know that they're actually typing
the password (edited just to illustrate the point, the actual output was
shamefully messy and perhaps needs fixing too):
$ nmcli c up Wrathmosphere
Passwords or encryption keys are required to access the wireless network 'Wrathmosphere'.
Password (802-1x.password): *********
Having it in libnm doesn't make any sense and prevents using it for more
internal functionality.
Too bad nm_utils_wifi_strength_bars() is already a public API.
No problem -- replace it with a compatible yet dumber equivalent.
In most cases, it copies the entire strv needlessly.
We can do better.
Also, the max_tokens argument is handled wrongly (albeit
not used anywhere anymore).
In a later commit we'll add a new generic client function used by
nmcli and nmtui. nm-client-utils.c seems the right place for it, so
move the file to the base library that is used by both clients.
While at it, also put in that file some functions that will be needed
by nmtui.
These functions are only used by nm-meta-setting-desc.c. Make them internal.
Unfortunately, they are part of "common.h" which cannot be used without
the rest of nmcli. Still todo.
