Log:
[CMLIB][NTOS:CONFIG]
- The BaseBlock->Length member is really the size in bytes of the full hive, minus the
header (base) block size.
- Remove the last remnents of the "hack of doom" aka. the one similar in
magnitude to the US national debt, addendum to r61621 and r26712. The FileSize can be
computed with BaseBlock->Length.
