The frame_analyzer which is used by compare_videos.py needs to handle
barcode errors. As before the reference and the test video can contain
repeated frames. When there are barcode decode errors in the test video,
then we should not let that contribute to the skipped frames score. When
there are barcode decode errors in the reference video, then we need to
take proper care to still calculate skipped barcodes when the
corresponding frames are not present in the test video and the test
video does not have a frame with a barcode decode error that could have
been the same frame as the one in the reference.
A new metric total number of skipped frames and for number of decode
errors is introduced. Barcodes that appears in the test video, but not
in the reference video are also listed.

Issue: This API was calculating the file_header and frame_header offset only for the first frame which is not the right logic. We need to skip the file and frame header every time we extract a new frame.
Also added a unit test case which compares the extracted frame with the frame stored in text file.

Breaking some trybots due to memory error.

Add support for --label flag to the frame_analyzer, that
decides what label shall be used for the perf output.
BUG=none
TEST=
Make sure to have zxing and ffmpeg in the PATH.
Create a captured video (from running vie_auto_test custom call)
webrtc/tools/compare_videos.py --ref_video=reference_video.yuv --test_video=captured_output.yuv --frame_analyzer=out/Release/frame_analyzer --label=TEST_VGA
And then inspecting the output that is prefixed with RESULT.
