3495d20dbe Multiply all cursor step cost estimates by the estimated size of the row in 
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.
