The 50 methods that appeared on the GC stacks of the most applications
require 13KB of native heap for their uncompressed register maps, and
the full set took 5ms to uncompress. Pre-computation doesn't represent
a significant improvement in space or time, at the cost of a big pile
of strings in ZygoteInit.
I'm leaving the method in ZygoteInit, but it's not called, and the
static final String[] of method descriptors is empty. We may want to
revisit this later.

2 levels as recorded at plug and unplug events. During charge cycles this would be useful because it would tell us
what the start and end levels were in the last discharge cycle. However during a discharge cycle this information could
be misleading as it would give you the level at the last unplug event (beginning the the discharge cycle) and last plug
event (end of the previous discharge cycle).
Now we are still keeping track of 2 values, but they are "discharge cycle start level" and "discharge cycle current level".
During a discharge cycle this will give you the level the current discharge cycle started at, and the current level. During
a charge cycle the same data will be supplied as before (the start/end of the last discharge cycle).
