Allow boards to optionally include loadkeys to set a custom keymap.
showkey and dumpkeys (normally only needed for development) can also be
optionally included.
Remove *.map from .gitignore; this was probably intended for build
artifacts that are now excluded via the build/ directory.
Add reboot and poweroff to shell history, which is useful for devices
lacking full hardware keyboards to escape the recovery shell with just
"up" and "enter".

Build kbd and ship setfont if enabled with CONFIG_KBD.
When CONFIG_KBD is enabled, setconsolefont.sh will double the console
font size on large displays (>1600 lines tall as a heuristic).
