Sample rows from clusters.

Assumes clusters have been loaded by loadClusters/loadOneCluster.

Parameters:

	nRows	total number of rows in the clusters; if set to 0, full table scans should be done
	nRowsActual	actual total number of rows in the clusters
	nCols	number of columns in each cluster
	nClusters	number of clusters
	proj	columns to be projected
	skipRows	read every "skipRows" rows
	mode	sampling mode (SAMPLING_BERNOULLI or SAMPLING_SYSTEM)
	rate	sampling rate
	seed	Bernoulli sampling RNG seed
	clumps	number of system sampling clumps
	expectedNumRows	expected number of rows in scan result; normally should be the same as nRows unless skipping rows or testing exception cases

Generate bitmaps to pass as input into row scan exec stream.

Parameters:

	nRows	number of rows in table
	skipRows	generate rids every "skipRows" rows; i.e., if skipRows == 1, there are no gaps in the rids
	bitmapTupleDesc	tuple descriptor for bitmap segment
	pBuf	buffer where bitmap segment tuples will be marshalled

Returns:

size of the buffer containing the marshalled tuples

Configuration parameters can also be set ad hoc, from the command line, as pairs name=val. These take precedence.
