Corinna Vinschen c02ac89f28 Add -i/--input option to locale(1) 
The default UI language returned by GetUserDefaultUILanguage does not
necessarily reflect what the user really wants.  E. g., the system could
be en_US, but the desired language is en_CA, without having a CA langpack
installed.

Changing the settings under "Languages" and changing the keyboard layout
is only affecting the so-called  "Input language", while what's returned
by GetUserDefaultUILanguage is the "Display language".  Changing the
latter requires installing MUI langpacks.

Thus, we introduce a way to fetch the "Input language" using the -i or
--input option.

Also clean up documentation of locale(1).
