The CellSignalStrengthCdma class previously allowed
the values in the class to be kept as negative ints
but expected them to be parceled as positive ints.
This led to a confusing mess that is best unwound
by calling the actual constructor for the class and
letting the parcel values be an implementation detail.
This CL removes all of the parcel-time coersion and
instead expects that the class be constructed using
a constructor rather than by manually parceling and
then using the class to un-parcel. In addition, the
range checking for inputs is now done only once, and
values are no longer mutated in the parcel/unparcel
process.
