We should disable using imgdiff if *any* of the source and target
partitions uses squashfs.

We use imgdiff to handle files in zip format (e.g. jar/zip/apk) for
higher compression ratio.
For system/vendor in squashfs, a) all files are compressed in LZ4
format; b) we use 4096-byte block size in their sparse images, but the
files in squashfs may not be laid out as 4K-aligned. So the blocks for
a given file as listed in block map may not form a valid zip file, which
may fail the patch generation with imgdiff.
Disable using imgdiff for squashfs images, and use bsdiff instead.

The first line returned by awk is empty. In consequence, when
fs_config computes its mode it will consider this line as a file (no
trailing slash) and affect the default android_files mode which is
0644. The mode for the root directory should be the default
android_dirs mode 0755.
Add a special case in fs_config to consider empty line as a directory.

This moves build/tools/apksigner/core to its own project tools/apksig.
The move also renames the moved Java packages from
com.android.apksigner.core.* to com.android.apksig.* to reflect the
new name of the library.

add_img_to_target_files.py has an option of "-a" to add missing
images only. Under this option, the script should skip copying
the radio images for A/B devices when given image exists already
under "IMAGES/".
Test: Run the command on an A/B device, the existing radio images under "IMAGES/" don't get overwritten; and missing images are added correctly.

This adds an APK signer primitive which preserves as much of the input
APK as possible. For example, it preserves the order of APK entries
and preserves their contents, including compressed form and alignment
of data.

For A/B OTAs, by default it calls 'openssl pkeyutl' to sign the payload
and metadata with the package private key. If the private key cannot be
accessed directly, a payload signer that knows how to do that should be
supplied via "--payload_signer <signer>".
The signer will be called with "-inkey <path_to_private_key>",
"-in <input_file>" and "-out <output_file>" parameters.
Test: Use a dummy signer, call 'ota_from_target_files.py --payload_signer <signer> <target_files.zip> <ota.zip>' and verify the signatures in the generated package.

Replace verity keyid with the keyid extracted from cert

extracted from --replace_verity_keyid and written to the

This surfaces relevant NoSuchAlgorithmExceptions to the caller instead
of rethrowing as other exception types. Some setups need to be able to
distringuish issues due to their own misconfiguration
(required crypto algorithm mising -- NoSuchAlgorithmException) from
issues with the APK being signed or verified.

verifying APK JAR signatures. Unfortunately, the behavior of Android
kept changing in interesting ways between different platform versions.
This is hard-coded as a big lookup.

For acp, we've been using an old prebuilt in prebuilts/sdk, but it's not
part of the SDK. Instead, we'll use a prebuilt in the build-tools
repository.
For ijar, we've been using the host libstdc++ to workaround the lack of
libc++ on some unbundled branches. Instead, use a prebuilt that can use
libc++.
For ziptime, we've been disabling it on unbundled branches, due to the
lack of libc++. Instead, use a prebuilt version of ziptime that can use
the prebuilt libc++.

This switches PKCS#7 SignedData generation code from Bouncy Castle to
OpenJDK's proprietary internal API. This is to avoid depending on a
huge library that's not really needed. In the longer term, it's best
to add our own implementation of PKCS#7 SignedData building, parsing,
and verification. This will give the code more power to mimic what the
Android platform does.

This patch uses subprocess.communicate instead of subprocess.wait to
prevent deadlock if any of the child processes outputs too much data,
and redirects the subprocess output to stdout when running in verbose
mode.
With this patch `ota_from_target_files -v` prints the delta_generator
output in stdout, and no output if '-v' is not passed.

This adds the ApkVerifier class which verifies APKs using APK
Signature Scheme v2 only. In a follow-up commit this class will be
extended to verify APKs using JAR signature scheme when necessary.
The APK verifier is designed to not just verify an APK, but also
report errors, warnings, and information about signers in a structured
way, to enable tools to surface this information to users in various
ways.

This modifies JAR signing code to produce DSA signatures which are
accepted by all Android platforms rather than only API Level 9 and
higher.
The issue is that by default Bouncy Castle uses OID 1.2.840.10040.4.3
(dsaWithSha1) in PKCS #7 CMS SignerInfo whereas Android accepts that
only since API Level 9. However, OID 1.2.840.10040.4.1 (dsa) is
accepted by all Android platforms.
