- standardisded on a single context argument
- removed Device.init() no longer necessary as initilize now
automatically gets propagated up the hierarchy. Renamed the existing
use of it to "initilize".
- related pylint cleanup.
uname is not available on all Android devices, and we cannot rely on
busybox for establishing the ABI, as we need to get the ABI before we
can depoly the right version of busybox.
In both cases, the ABI is now obtained by executing "uname -m" on the
device and perfroming a mapping from the returned machine architecture
a known ABI. If no known ABI is found the architecture string itself is
returned.
added more paths to pull by default when device.get_properties is
invoked during run initialization. Also moved the LinuxDevice
implementation into BaseLinuxDevice, so that AndroidDevice tires to pull
the same files (on top of the Android-specific stuff).
