common: cli_readline: Improve command line editing
This improves the cread_line() function so that it will correctly
process the 'Home', 'End', 'Delete' and arrow key escape sequences
produced by various terminal emulators. This makes command line editing
a more pleasant experience.
The previous code only supported the cursor keys and the 'Home' key, and
only for certain terminal emulator configurations. This adds support for
the 'End and 'Delete' keys, and recognises a wider range of escape
sequences. For example, the left arrow key can be 'ESC O D' instead of
'ESC [ D', and the 'Home' key can be 'ESC [ H', 'ESC O H', 'ESC 1 ~' or
'ESC 7 ~', depending on what terminal emulator you use and how it is
configured.

value).
