24384d1d1e Added overloaded version of Deserializer::ReadOwnedPtr which allows
the target pointer to be passed by reference.  This can result in less
typing, as the object to be deserialized can be inferred from the
argument.

ff37ccc570 Removed ReadVal from SerializeTrait<T>, and also removed it from
Deserializer.

There were issues with Visual C++ barfing when instantiating
SerializeTrait<T> when "T" was an abstract class AND
SerializeTrait<T>::ReadVal was *never* called:

template <typename T>
struct SerializeTrait {
 <SNIP>
  static inline T ReadVal(Deserializer& D) { T::ReadVal(D); }
 <SNIP>
};

Visual C++ would complain about "T" being an abstract class, even
though ReadVal was never instantiated (although one of the other
member functions were).

Removing this from the trait is not a big deal.  It was used hardly
ever, and users who want "read-by-value" deserialization can simply
call the appropriate methods directly instead of relying on
trait-based-dispatch.  The trait dispatch for
serialization/deserialization is simply sugar in many cases (like this
one).

066ff5b7f2 Rewrote backpatcher. Backpatcher now stores the "has final pointer"
flag in the **key** of the backpatch map, as opposed to the mapped
value which contains either the final pointer, or a pointer to a chain
of pointers that need to be backpatched.  The bit flag was moved to
the key because we were erroneously assuming that the backpatched
pointers would be at an alignment of >= 2 bytes, which obviously
doesn't work for character strings.  Now we just steal the bit from the key.

eb9409dbb9 Implemented deserialization of references. References are handled
just like pointers, except that they cannot be backpatched.  This
means that references are essentially non-owning pointers where the
referred object must be deserialized prior to the reference being
deserialized.  Because of the nature of references, this ordering of
objects is always possible.

Fixed a bug in backpatching code (returning the backpatched pointer
would accidentally include a bit flag).

5973ef40ca Updated backpatching logic during object deserialization to perform
eager backpatching instead of waithing until all objects have been
deserialized.  This allows us to reduce the memory footprint needed
for backpatching.

6a13dfdc6d Added default implementation of SerializeTrait<> that dispatches to
calling member functions of the target type to perform type-specific
serialization.
                         
Added version of ReadPtr that allows passing references to uintptr_t
(useful for smart pointers).

3bd9dcc08f Updated backpatching during object deserialization to support "smart"
pointers that employ unused bits in a pointer to store extra data.

6e9b496643 Split Serialization.h into separate headers: Serialize.h and
Deserialize.h Serialization.h now includes trait speciailizations for
unsigned long, etc.
