Convert to use direct access to the data store (instead of bb.data.*Var*())

This is the result of running the following over the metadata:

sed \
-e 's:bb.data.\(setVar([^,()]*,[^,()]*\), *\([^ )]*\) *):\2.\1):g' \
-e 's:bb.data.\(setVarFlag([^,()]*,[^,()]*,[^,()]*\), *\([^) ]*\) *):\2.\1):g' \
-e 's:bb.data.\(getVar([^,()]*\), *\([^(), ]*\) *,\([^)]*\)):\2.\1,\3):g' \
-e 's:bb.data.\(getVarFlag([^,()]*,[^,()]*\), *\([^(), ]*\) *,\([^)]*\)):\2.\1,\3):g' \
-e 's:bb.data.\(getVarFlag([^,()]*,[^,()]*\), *\([^() ]*\) *):\2.\1):g' \
-e 's:bb.data.\(getVar([^,()]*\), *\([^) ]*\) *):\2.\1):g' \
-i `grep -ril bb.data *`
