Description

QOutProcessor has

    ppm.add(new PatternReplacementPair(Pattern.compile("\\{\"writeid\":[1-9][0-9]*,\"bucketid\":"),
        "{\"writeid\":### Masked writeid ###,\"bucketid\":"));

which causes something like

{"writeid":### Masked writeid ###,"bucketid":536870912,"rowid":0}	2
{"writeid":### Masked writeid ###,"bucketid":536870912,"rowid":1}	3

in the *.q.out file. For example, acid_meta_columns_decode.q

This was needed when the ROW__ID contained global transaction ID which
changed depending on which tests were ran previously. Since 3.0, ROW__ID uses per table writeId which is stable and is safe to put in the .out file
