@abstract Structure for one alignment covering the pileup position.
@field  b      pointer to the alignment
@field  qpos   position of the read base at the pileup site, 0-based
@field  indel  indel length; 0 for no indel, positive for ins and negative for del
@field  is_del 1 iff the base on the padded read is a deletion
@field  level  the level of the read in the "viewer" mode

@discussion See also bam_plbuf_push() and bam_lplbuf_push(). The
difference between the two functions is that the former does not
set bam_pileup1_t::level, while the later does. Level helps the
implementation of alignment viewers, but calculating this has some
overhead.

  @discussion Notes:

   1. qname is zero tailing and core.l_qname includes the tailing '\0'.
   2. l_qseq is calculated from the total length of an alignment block
      on reading or from CIGAR.
