Organize barcode codes into modules.

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.

As long as we're moving stuff around, can we get rid of the redundant /src
directory following /fxbarcode?  There's nothing else in fxbarcode/ except for
src/.  Thanks!

Sure and that's what I thought too. Same thing happens in other folders as
well...

Many thanks for also getting rid of the include directories.  Its much easier to
work in a world where the .h and .cpp have the same name and live in the same
directory.  If this builds, its fine. LGTM.

I can build with ninja gyp, so changes in gyp should be fine.

Having trouble with gn build, which broke in xfa branch, although seems related
to freetype.
Can you take a look at https://codereview.chromium.org/815103002#msg12 ?

Once that's fixed, I will land.

Now build both with gyp and gn. Landing now.
