It allows for getting and setting the background color. Notably, Vim uses
OSC 11 to learn whether it's running on a light or dark colored terminal
and choose a color scheme accordingly.
Tested with gnome-terminal and xterm. When called with "?" argument the
current background color is returned:
$ echo -ne "\e]11;?\e\\"
$ 11;rgb:2323/2727/2929

Changed in v2:
* Reordered the type condition by their numeric value
* Updated the places that iterate oscs[] with correct array length
* Backed out the change of the OSC terminator sequence
