* Added flow summaries for the BDE `bslx` byte-stream deserializers (`BloombergLP::bslx`). Constructing a `ByteInStream` or `GenericInStream` from a byte buffer or streambuf taints the stream, each `get*` method (`getInt32`, `getString`, `getArray*`, ...) propagates that taint into the deserialized output (and keeps the returned stream tainted for chained calls), and `InStreamFunctions::bdexStreamIn` propagates taint from the stream to any deserialized object.
