0c6c135967 Go: exclude protobuf read steps from cleartext-logging query
This query already treats structs differently to usual: it includes field -> whole struct taint steps, but explicitly excludes struct -> field steps. This means that a logging framework sinking an entire struct with a tainted field yields an alert, but we don't get FPs caused by writing field `x` but then reading field `y`.

However, protobuf messages have a special treatment, with taint usually associated with the whole struct and getter methods propagating that taint out. Suppressing these getter method steps specifically for the cleartext-logging query mirrors its treatment of structs in general and avoids this sort of field-mismatch FP.

On the downside we will miss same-field propagation like `m.field = password; Log(m.GetField())` if we don't have source code for the implementation of `m`. However this is hopefully unusual since the typical use of protobufs is to serialize and deserialize, rather than using the struct as a general-purpose datastructure.

8266a22332 Kotlin: fix method types when an inherited method implements a collection type
In this circumstance the compiler seems to generate a specialised version of the implementing function with its argument type replaced by the interface-implementing child class' type parameter. However it stores a back-pointer to the real declared function, which we should use as the call target.
