Organize barcode codes into modules.
Previously all the files in barcode are lumped together. The naming of some files are inconsistent, leading to difficult understanding of the structure. Now files are grouped based on different barcode type like in zxing. This also matches what it looks like in other xfa folders. The file names in each folder could be further modified to be consistent. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/842043002
