Selecting the right ABI
-----------------

During the development of android 7, qualcomm made changes to the android
hardware level APIs. They added support for a secondary builtin display, and
made other changes. This affected the existing ABI of the hardware compositor
module (HWC). Since this change affected the values passed between the parts of
the platform in a sublte way, the platform is now configured at build time,
resulting in two platform modules.

Thus the android platform of mir needs to identify the type of HWC module at
load time. The check for the HWC ABI happens with the help of android properties
and the vendor name of the HWC module. The following properties are checked:
- ro.build.version.release
- ro.build.vanilla.abi
- ro.build.qti_bsp.abi

The changed ABI version of the platform is named after the project CodeAurora
Forum (CAF). It will be selected when the hwc vendor name is 'CodeAurora Form'
and the android version is newer than 7. When 'ro.build.vanilla.abi' is set, an
unchanged ABI is assumed, while 'ro.build.qti_bsp.abi' does the opposite.
