- Make TypeCreator and TreeCreator extend Serializable.
- When replacing a SerializedTypeTag with a TypeTag or WeakTypeTag,
do not use scala.reflect.runtime.universe.rootMirror, since
it is unlikely to find user classes; instead, create a runtime
mirror using the context ClassLoader of the current thread.
Use the same logic for SerializedExpr.
- Remove writeObject/readObject methods from SerializedTypeTag
and SerializedExpr since they are unused.
- Add @throws annotation on writeReplace and readResolve methods.
- Handle SecurityException if the current thread cannot access the
context ClassLoader.
- To make type tags of primitive value classes serializable, make
PredefTypeCreator a top-level class. Otherwise, it would
retain a reference to the enclosing Universe,
rendering the TypeCreator non-serializable.
Binary compatibility:
- Keep nested PredefTypeCreator class to avoid backward binary
incompatible change.
- Keep `var` modifiers on the class parameters of
SerializedTypeTag for backward binary compatibility.
- Adds filter rules to forward binary compatibility whitelist:
- `TypeCreator`, `PredefTypeCreator`, and `TreeCreator` must now
extend from `Serializable`.
- Must have new class `scala.reflect.api.PredefTypeCreator`
to avoid problematic outer reference.

This brings all the files into line with the .gitattributes
settings, which should henceforth be automatically maintained
by git.

As the experience has shown, there's no need for a separate layer of reflection
in scala-library.jar. Therefore I'm putting an end to it.

Instead of trying to serialize the entire universe and failing miserably
(which happens now), exprs and type tags will now serialize their creators
and deserialize into scala.reflect.basis.
Since creators produced by reification are not serializable right now,
serialization will crash. That's a small improvement over state of the art
functionality-wise, but it's a step forward robustness-wise.
Next step in this direction is generation of serialization code for creators.
