Many source files under vendor/google_devices
are old third party code with too many clang-tidy
misc-macro-parentheses warnings.

sign_target_files_apks.py calls common.GetBootableImage() but without
calling 'OPTIONS = common.OPTIONS' first. In common.GetBootableImage(),
we should use the local info_dict parameter instead of OPTIONS.info_dict.
Test: sign_target_files_apks.py generates signed-TF.zip successfully.

This shouldn't be necessary for most makefiles, since we add
$(LOCAL_GENERATED_SOURCES) to this already included, but for prebuilts
that aren't actually prebuilts (Soong modules), we need to pass
dependencies so that the generated headers are built before being used.

This updates the build system for the new Android Verified Boot
codebase. As this is based on Brillo Verified Boot, this change replaces
the existing BVB support.
Android Verified Boot is enabled by the BOARD_AVB_ENABLE variable
BOARD_AVB_ENABLE := true
This will make the build system create vbmeta.img which will contain a
hash descriptor for boot.img, a hashtree descriptor for system.img, a
kernel-cmdline descriptor for setting up dm-verity for system.img and
append a hash-tree to system.img.
Additionally, the descriptors are left in boot.img and system.img so a
third party can create their own vbmeta.img file linking - using the
option --chain_partition - to these images. If this is not needed
footers can be erased using the 'avbtool erase_footer' command. It's
also harmless to just leave them in the images.
By default, the algorithm SHA256_RSA4096 is used with a test key from
the AVB source directory. This can be overriden by the
BOARD_AVB_ALGORITHM and BOARD_AVB_KEY_PATH variables to use e.g. a
4096-bit RSA key and SHA-512:
BOARD_AVB_ALGORITHM := SHA512_RSA4096
BOARD_AVB_KEY_PATH := /path/to/rsa_key_4096bits.pem
To prevent rollback attacks, the rollback index should be increased on a
regular basis. The rollback index can be set with the
BOARD_AVB_ROLLBACK_INDEX variable:
BOARD_AVB_ROLLBACK_INDEX := 5
If this is not set, the rollback index defaults to 0.
The variable BOARD_AVB_MAKE_VBMETA_IMAGE_ARGS can be used to specify
additional options passed to 'avbtool make_vbmeta_image'. Typical
options to be used here include '--prop', '--prop_from_file', and
'--chain_partition'.
The variable BOARD_AVBTOOL_BOOT_ADD_HASH_FOOTER_ARGS can be used to
specify additional options passed to 'avbtool add_hash_footer' for
boot.img. Typical options to be used here include '--hash_algorithm' and
'--salt'.
The variable BOARD_AVBTOOL_SYSTEM_ADD_HASHTREE_FOOTER_ARGS can be used
to specify additional options passed to 'avbtool add_hashtree_footer'
for systems.img. Typical options to be used here include
'--hash_algorithm', '--salt', and '--block_size'.

In BBOTA, we generate patches based on _all_ the blocks of a pair of
input files (src and tgt). For security incremental OTAs, one common
pattern is that only a few blocks are changed in odex files (e.g.
headers). We don't really need to stash/patch the unchanged blocks.
This CL analyzes the unchanged blocks in odex files and computes the
diff for the changed blocks only. It reduces the OTA install time by
about 25% to 40% in our experiments, by paying an increase of 5% to 30%
OTA generation time cost.
