[-- Attachment #1: Type: text/plain, Size: 69632 bytes --]

Add a new Backtab keysym (KT_FN index 30) that produces the standard
backtab escape sequence \e[Z. This replaces F246 which was unused.

Update all keymaps to use Backtab for Shift+Tab instead of Meta_Tab.
In most cases the Meta_Tab binding already existed for Alt+Tab; where
it was missing, it has been added.

This change affects keymaps across all architectures: i386, amiga,
atari, mac, sun, and pine.

From v2:

Moved Backtab to index 255 — the last slot in the KT_FN table, which has 
no kernel UAPI name (the kernel only goes up to K_F245 = K(KT_FN, 254)).
