[1/2] SystemUI: Update network traffic indicator

Android measures the amount of data transferred in bytes,
however, by convention, data rates should be measured in bits
per second.

*Convert the change in total data and time to bits and seconds,
and then divide the amount transferred by the number of
seconds that have elapsed.

*Update the labels and have them use the correct SI prefixes.

*Factor out or add @hide to public methods and constructors

*Remove all Runnables and Messages from Handler queue when
disabled

*Minor formatting changes to stay consistent with Android's
code-style guidelines.

PS2: Set maximum digits to prevent it from filling the statusbar
PS3: Rebase
PS4: Add ability to display either bits or bytes
