This makes two types of fix:
1. Align parameter names on overridden methods where the superclass
has `@param` javadoc.
2. Use `@hide` on `protected final` methods that refer to package-private
types. This will hide these symbols from Dackka javadoc generation
but not (currently) from the artefacts distributed on Maven. These
methods are currently unusable outside their package anyway (e.g. by
external developers) because of the dependency on a package-private
type.
This also changes some HLS, SmoothStreaming, and IMA code where I've renamed
parameters of overridden methods to be consistent across the type
hierarchy.
