Feature #6152 (Variant Annotation Tool): Added annoStreamVcf, whichled to yet more significant changes to annoRow: instead of every row
declaring its type and annoRow{Free,Clone} taking a numCols argument
that is meaningless for wig, now annoRow{Free,Clone} take the row's
source annoStreamer as an argument.  The annoStreamer now has public
members (rowType and numCols) that provide all information needed about
the row.  annoStreamer constructors need to set rowType.
