misc: Rename the (De|En)codeVarint function _(De|En)codeVarint32.

DecodeVarint implicitly truncates its inputs to 32 bits, and that should be
obvious from its name, and so not a surprise to the caller. EncodeVarint also
has the suffix added for consistency. Both functions are only used in
protolib.py, so add a _ to make it private (in the python sense) to the
module.
