c0f77ee489 Check the completeness of original blocks during target files validation
The validate_target_files.py checks the 'incomplete' field of the range
in file_map. And range has already considered the shared blocks and
could be smaller in size than the original file range. Therefore, the
'incomplete' flag was set on the original range in common.py; and we
should switch to use the original range also during validation.

I also checked another flag usage in CanUseImgdiff(), and it has
explicitly rejected cases of shared blocks.

65b94e92be releasetools: Add a common base class for unittests.
All the releasetools unittests extend the common base class of
test_utils.ReleaseToolsTestCase. Define tearDown() in the base class to
do the clean-up works.

73dd4f45f3 releasetools: Set default stdout and stderr in common.Run().
stdout and stderr will default to subprocess.PIPE and subprocess.STDOUT
respectively (which is the expected behavior from most of the existing
callers), unless caller specifies any of them.

c6bd70a5e6 releasetools: Raise on image building errors.
The image building functions in build_image.py have been returning
(success, result) or special values to indicate the validity of the
result. The same logic can be better expressed by raising exceptions
instead, because
 a) using a special value relies on caller to check for that magic
    value;
 b) exceptions can carry additional messages other than a boolean does,
    e.g. the output from the failing command;
 c) caller can have cleaner code flow without explicitly checking for
    the validity of the result.

This CL changes such functions to raise on errors. The majority of these
functions are internal to build_image.py only, except for BuildImage()
that has a few callers in add_img_to_target_files.py (which all die upon
error anyway).

Test: `m dist`
Test: python -m unittest test_build_image
Test: python -m unittest test_add_img_to_target_files
Test: python -m unittest test_validate_target_files
Test: Inject an error to the depended binaries (e.g. avbtool), and check
      that build_image.py exits with error messages.

35f4ebc957 releasetools: Clean up the use of partition_size.
Unless using dynamic partitions, `partition_size` should be a fixed
value that equals to the partition size in BoardConfig. It should stay
the same when building an image for that partition. Only the actual
image size that's used to hold the filesystem could be adjusted. This CL
cleans up the uses of `partition_size` and `image_size` to better
reflect such logic.

With dynamic partitions, the only thing that changes is the need to
compute `partition_size` upfront. Once that's done, `partition_size`
should remain unchanged.

b4ec6d752a Remove the hard-coded path of build_verity_metadata.py.
build_image.py used to invoke build_verity_metadata.py with a hard-coded
path of 'system/extras/verity/build_verity_metadata.py', which makes it
hard to run unittests from non-$(ANDROID_BUILD_TOP) directory.

This CL adds the dependency on the tool, so that it gets installed to
$(HOST_OUT_EXECUTABLES), then removes the hard-coded path.

ba557707d8 releasetools: Support validating Verified Boot images.
For a given (signed) target-files.zip, this CLs allows verifying the
Verified Boot related images. It works with both of VB 1.0 and VB 2.0
images.

As part of the CL, it also moves validate_target_files.py to argparse,
which is more flexible than the traditional getopt module.

Also add unittests for the VB 1.0 path. VB 2.0 tests will be added in
follow-up CL.

Example usage:

- Run the script on aosp_bullhead target-files.zip.

$ ./build/make/tools/releasetools/validate_target_files.py \
    --verity_key build/target/product/security/verity.x509.pem \
    --verity_key_mincrypt build/target/product/security/verity_key \
    aosp_bullhead-target_files-4522605.zip

- Run the script on aosp_walleye target-files.zip.

$ ./build/make/tools/releasetools/validate_target_files.py \
    --verity_key external/avb/test/data/testkey_rsa4096.pem \
    aosp_walleye-target_files-4627254.zip
