The existing code for method StreamingMemoryObject.fetchToPos does not respect
the corresonding call to setKnownObjectSize(). As a result, it allows the
StreamingMemoryObject to read bytes past the object size.
This patch provides a test case, and code to fix the problem.

The reading of 64 bit values could still be optimized, but at least this cuts
down on the number of virtual calls to fetch more data.

Returning more information will allow BitstreamReader to be simplified a bit
and changed to read 64 bits at a time.

Every MemoryObject is a StreamableMemoryObject since the removal of
StringRefMemoryObject, so just merge the two.
I will clean up the MemoryObject interface in the upcoming commits.
