Based on patches by jruesga from CyanogenMod sources. This commits adds
support for the Asus Transformer dock special keys. For this commit to 
work, kernel and device tree commits are needed to implement the device 
specific handling

Support NoGapps style package signature faking

Unfortunately due to GMSCore libraries for clients carrying out signature checks on the GMS app,
users are not able to use open source equivalents, and are being strong-armed (by apps) into using
non-free libraries for these functions. NoGapps is an open source implementation of these libraries.

Unfortunately, a patch like this is necessary in order to permit apps to be convinced they are talking
to the closed-source GMSCore. As this "DRM" is implemented at app-level, it's possible to do this,
without the Android OS itself being "fooled" by the faked signatures.

This commit is from the NoGapps project, I am just submitting it on their behalf.
