Fix buffer size: 64bit GLBufferSizeTracker, hash over addr+size, save fail-fast hash cache, ..

Relates to GlueGen 6b6b9b3b81cdc85b7260664ebec547756a6be5d7, branch sgothel_wip_fixes01.

Memory object size is ptrdiff_t, hence long (64bit).
The hash value must include size as well, otherwise boundaries cannot be verified. (security)
Double check hash collisions while adding a new MemoryObject.
