change a varchar field to a longblob in gwasCatalog because it wasn't
big enough to hold the data in the flat files.
Fixing corner case: if we hit the end of rowBuf in nextRowFromBuffer,
then discover in asdDoQueryChunking that we don't need to query again,
then we need to reset rowBuf because when we return to nextRowFromBuffer,
we check rowBuf->size which should be 0.  We could also check self->eof,
but I think it's cleaner to have the correct rowBuf state.
