Adding serialization support to utilib. See src/adt/utilib/Serialize.h
- new classes: Serialization_Manager, SerialObject?, SerialPOD
- bugfix: utilib/test/tests.cpp did not catch exceptions thrown by test
cases
- bugfix: In certain cases, assigning an Any to an empty AnyFixedRef?
created a reference to the original Any (instead of just
incrementing the reference count - led to segmentation fault in
specific cases where the original Any was a function return value)
- efficiency: Any::to_value_any() makes a better attempt to avoid
unnecessary copies
