We pack _all_ the APK certs info into META/apkcerts.txt at build time,
including the ones that are not installed for the target. When
detecting for compressed APKs, we should only count the ones that are
actually installed.

When creating ext4 images with mke2fs, it may skip allocating some
blocks if they contain all zeros. As a result, there could be less
blocks listed in the block map than the actual file length.
For example, for a file with a length of 112200-byte (27+ blocks),
the listed blocks in block.map could be '43665-43688' (24 blocks).
Because some all-zero blocks are not taking actual space.
The generated ext4 images are perfectly valid - kernel will figure out
that data block is not allocated and writes all zeros into user buffer.
However, we can't fully reconstruct a file from its block list in our
Python script. Ideally this can be avoided by mounting or parsing an
ext4 image directly, which is yet to be supported in our script.
This CL skips checking for such files to avoid failing
validate_target_files.py.

Test: validate_target_files.py passes on targets with mke2fs generated
images (e.g. marlin).

Some OWNERS files use secondary email addresses, so we only

Commit 21803d3574 only added compatibility
metadata for A/B OTA packages, because by that time we didn't use
'ro.treble.enabled' property to determine if a target was Treble-enabled.
This CL uses 'ro.treble.enabled' to guard the packing of compatibility
metadata for both of A/B and non-A/B OTA packages. It also switches to
checking the system/vendor fingerprints to determine if there's an
update to the partition (previously it was computing the SHA-1 of the
images, which may have unintentionally changed due to issues that give
non-repetitive builds).
Bug: 64339310
Test: Generate OTA packages (full and incremental) on Treble-enabled
targets (sailfish, as well as a non-A/B angler target with
Treble-enabled locally); check that the compatibility.zip entry
exists.
Test: Generate OTA packages on Treble-unenabled non-A/B target (angler);
check that the compatibility.zip entry doesn't exist.

This entry only exists in non-A/B full OTA path. However, this file has
never been loaded by recovery - recovery was only reading the one from
the recovery image (which also has been removed by a recent change in
[1]).

Compressed APKs can be identified by a "compressed=<ext>" entry in
the apkcerts.txt file. When we encounter such an entry, we need to
decompress the file to a temporary location before we process its
certs. When we're signing, we should also recompress the package
after it's signed.

Test: compared signed output before / after this change, verify that
it's bitwise identical when no compressed APKs are present.

In BOARD_AVB_MAKE_VBMETA_IMAGE_ARGS, if we have defined
"--include_descriptors_from_image" with an image file whose path points
to source tree, add_img_to_target_files.py or sign_target_files_apks.py
may fail to find the file. Because these scripts may run without a
source tree, by taking target_files.zip as the only input.
This CL scans additional locations in the input target_files.zip to find
those missing files in avb_vbmeta_args. As long as the files are included
in the target_files.zip, they get a second chance to be found.
Bug: 63910867
Test: As follows:
1. Setup BOARD_AVB_MAKE_VBMETA_IMAGE_ARGS with a local file path;
2. Remove the local file;
3. sign_target_files_apks.py fails without this CL;
4. sign_target_files_apks.py works.

Brotli has a better compression ratio than deflation. So for non-AB
full OTA, we can compress the new.dat with brotli first and store it
in the zip package.
This increase the OTA generation time by ~5 minutes for a full OTA
(measured based on 2.0G system.new.dat)

Currently we're writing META/misc_info.txt to the new TF.zip during
ReplaceVerityPrivateKey(). We should delay that until we have replaced
everything in need. Otherwise we won't be able to replace/overwrite
that zip entry (unless `zip -d` first).
This CL also cleans up the return value of ReplaceVerityPublicKey() and
ReplaceVerityKeyId(), since the caller no longer needs the values.
Test: sign_target_files_apks.py and check the generated signed TF.zip.
