camera_calibration_file can just be labeled
as camera_data_file. And use sensors_device
for the accelerometer.

Move bools into seperate file

By moving bools into a seperate file, the standard
BOARD_SEPOLICY_ functionality can be applied to override
and union booleans, and adjust values simply at build time.

Fix insertkeys.py to resolve keys.conf path entries in a portable way

Currently a path to a key in keys.conf must be fully qualified or have
the -d option appended. This fix will allow paths to have environment
variables that will be expanded. This will give portability to the
entries. For example the following entry will now be resolved correctly:
[@NET_APPS]
ALL : $ANDROID_BUILD_TOP/device/demo_vendor/demo_dev/security/net_apps.x509.pem
