[svn-r14353] Description:
- Add hash value for skip list string types, to reduce # of string
comparisons.
- Fixed bug with metadata/small data block aggregator adding size == 0
block into file free space list.
- Refactored metadata/small data block aggregator code into single set of
common routines.
- Changed block aggregator code to be smarter about releasing space in the
'other' block when the 'other' block has aggregated enough data.
Tested on:
