The signature size will be 512 bytes when signing the payload
with 4096 bits key. This cl determines the key size with
"openssl rsa -modulus"
The new key in testdata is generated by
"openssl genrsa -out testkey 4096"

Test: generate and verify an OTA package

For example, verify a target_files.zip that has system AVB-signed as a
chained partition.
$ build/make/tools/releasetools/validate_target_files.py \
signed-target_files-4904652.zip \
--verity_key verifiedboot_pub.pem \
--avb_system_key_path system_pub.pem
Note that verifiedboot_pub.pem should be the key (either public or
private) to verify vbmeta.img, and 'system_pub.pem' should be the key
(either public or private) for the chained partition of system.
testdata/testkey.key is the private key converted from
testdata/testkey.pk8 for testing purpose (`openssl pkcs8 -in
testdata/testkey.pk8 -inform DER -out testdata/testkey.key -nocrypt`).

The following is a buggy pattern that won't capture anything into err.
The issue is benign, since a failed run would be eventually captured by
a subsequent check.
p = Run(["aapt", ...], stdout=subprocess.PIPE)
output, err = p.communicate()
if err:
raise ...
This CL changes the error detection to be based on the return code from
aapt. It also adds some sanity test to ensure the call to aapt works.
The test app is built from AOSP com.android.cts.ctsshim (chosen mostly
because of its small size).
Test: python -m unittest test_common

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

Since we have been carrying test certificates in testdata/ for other
tests, do the same for test_sign_target_files_apks.py. Copy
verity.x509.pem from build/target/product/security/ to testdata/ for
that purpose.
Also capture the stderr output in ReplaceVerityKeyId().
Test: python -m unittest test_sign_target_files_apks

When calling 'openssl x509 -pubkey' to extract the public key from a
certificate, openssl 1.0 and 1.1 handle the '-out' parameter
differently. openssl 1.0 doesn't write the output into the specified
filename, which leads to the payload verification failure in
check_ota_package_signature.VerifyAbOtaPayload(). This CL addresses
the issue by always collecting the output from stdout instead.
It also refactors the two copies into common.ExtractPublicKey(), and
adds unittest. get_testdata_dir() is moved into test_utils.py that holds
common utils for running the unittests.

Test: python -m unittest test_common
Test: python -m unittest test_ota_from_target_files
Test: Run sign_target_files_apks with '--replace_ota_keys' on marlin
target_files zip. Check the payload pubkey replacement.
Test: Trigger the tests with forrest, and tests no longer fail on
machines with openssl 1.0.1.

Create a wrapper class that handles the payload signing, which unifies
the paths with and without external signer. Also add tests for the newly
added class.
The test keys under testdata/ are created with the script in
development/tools/make_key. testdata/testkey_with_passwd.pk8 uses
password "foo".
Test: python -m unittest test_ota_from_target_files
Test: Get identical A/B OTA packages w/ and w/o the CL.
