62724da930 Added versions of ReadPtr that takes an explicit SerializedPtrID. This allows 
clients of the Deserializer to read the pointer ID before they are ready
to deserialize the object (which can mean registering a pointer reference
with the backpatcher).

Changed some methods that took an argument "SerializedPtrID" to "const SerializedPtrID&" (pass-by-reference).  This is to accommodate a future
revision of SerializedPtrID where it may be much fatter than an unsigned
integer.

fe0c882e5a As Chris and Evan pointed out, BreakCriticalMachineEdges doesn't really need 
to be a pass of its own.  Instead, move it out into a helper method.

1a8a08a690 Added "random access" to the Deserializer to allow a client to jump to any 
serialized block in the bitstream, including a block in an entirely different
nesting than the current block. This is useful for deserializing objects from
a bitstream in an order different from the order that they were serialized.

48a396948f Updated Deserializer class to provide more information about the current 
block that is being visited in the bitstream.  The client can also now
skip blocks before reading them, and query the current abbreviation number
as seen from the perspective of the Deserializer.  This allows the client
to be more interactive in the deserialization process (if they so choose).

ec8cd06555 Added typedef "SerializedPtrID" to represent the pointer handle written to disk 
instead of just using "unsigned".  This gives us more flexibility in changing
the definition of the handle later, and is more self-documenting.

Added tracking of block stack in the Deserializer.  Now clients can query
if they are still within a block using the methods GetCurrentBlockLocation()
and FinishedBlock().
