platform_build/tools/releasetools/img_from_target_files.py
Tao Bao 32fcdab512 releasetools: Switch to Python logging.
Converts the following files to Python logging.

add_img_to_target_files.py
blockimgdiff.py
build_image.py
check_ota_package_signature.py
common.py
img_from_target_files.py
make_recovery_patch.py
ota_from_target_files.py
sparse_img.py
verity_utils.py

This separates logging outputs from normal outputs, and allows easier
switching between different verbosity levels. It also supports adjusting
logging config via environment variable (LOGGING_CONFIG).

Test: `m dist`
Test: `python -m unittest discover build/make/tools/releasetools`

Given a target-files zipfile, produces an image zipfile suitable for
use with 'fastboot update'.
Usage: img_from_target_files [flags] input_target_files output_image_zip
-z (--bootable_zip)
Include only the bootable images (eg 'boot' and 'recovery') in
the output.
