This makes it possible to compile on the bots without hardcoding paths
to Ant, Java and ffmpeg deep into the Python scripts (hardcoded paths exists only in the buildbot configuration).
For bots, the ANT_HOME, JAVA_HOME and FFMPEG_HOME environment variables must be set to the install locations for each of these dependencies, for Windows.
This CL also improves the return code handling to make failures easier to detect when things break.
TEST=running build_zxing.py without Ant or Java in the PATH, but with
ANT_HOME, JAVA_HOME and FFMPEG_HOME set. Running Chromium's src/chrome/test/functional/webrtc_video_quality.py.

These changes make the execution abort earlier on an error (like a tool is not found) and makes it easier to figure out what's wrong.
Made build_zxing.py executable.
BUG=None
TEST=Local runs of the PyAuto test src/chrome/test/functional/webrtc_video_quality.py in Chromium.

The barcode encoder generates barcodes as PNG files, than converts them to YUV files,
then stitches these into one YUV video file and finaly overlays this video over the
base video to produce a YUV video of the base with encoded barcodes in the upper part
of the video.
The decoder gets a YUV video with overlaid barcodes and first splits it into PNG files,
than decodes every file, and finally generates a stats file.
The encoder and decoder use Zxing and its Java command-line tools for the encoding and
decoding. They also use ffmpeg for the conversion between PNG and YUV and vice versa.

The tools could be used from trunk as:
./tools/barcode_tools/barcode_encoder.py --barcode_height=32 --base_frame_width=352
--base_frame_height=288 --base_yuv=<path_nad_name_to_base_file>
--output_yuv=<path_nad_name_to_output_file>
./tools/barcode_tools/barcode_decoder.py --yuv_file=<path_and_name_to_yuv_file>
--yuv_frame_width=352 --yuv=frame_height=288 --barcode_height=32
--stats_file=<path_and_name_of_stats_file>
By default the width of the barcodes is the same as the width of the base YUV frames.
This could be changes with the command-line option --barcode_width
