bytes, in order to get the query planner ot make use of estimated row sizes.
This check-in uses magic numbers in a few places (for example, estimates of
the size of output rows) and needs lots of refinement.  Consider this a
proof-of-concept only.

e13e9f54b0 Completely remove the iScanRatio field. The PRAGMA index_list(TABLE) command 
shows the estimated row size in the forth column.  It also generates a row
for the table with an index name of NULL.  The query planner still does not
take row size estimates into account - that is the next step.
