This file has not been synchronized with the one in Poky since previous
versions of DEY. Not much has changed, but sync it anyway.
Also:
* Get SHOWCURSOR from formfactor config files, but fallback to one
value depending on HAVE_TOUCHSCREEN if it was not configured.
* Rename the bbappend to the version generic '_%.bbappend'
