In aosp/1581143 , we banned generation of SPL downgrade OTAs. However,
caller of OTA script can still force an SPL downgrade OTA by passing
--spl_downgrade flag. If this flag is specified, we propagate it to OTA

At the end of OTA generation, we will use some private key to sign the
OTA payload. Since signing happens after the payload is being generated,
if caller passes an incorrect key path, caller won't notice it until 1
hour later when delta_generator finishes. At which point caller has to
staart from scratch, pass in another key path, and wait for an hour.
Let's detect incorrect key path before calling delta_generator, so
caller will get an error message right at beginning.

Previously we allow all spl downgrade OTA to generate. But applying such
OTA often causes device to hang and rollback, because keymaster refuses
to attach if it detects spl downgrade. When such error happens, it's
really hard to debug. So instead of debugging a mysterious boot failure,
let''s prevent such OTA from generating in the first place.

Background in http://go/android-partial-updates. For partial update
(e.g. system-only) or devices with mixed build, the current
fingerprint & device name no longer suffice as the precondition to
install the package.
Therefore, we need to additionally include the per-partition build
props into the ota metadata. We also define a protobuf for the metadata
so it can be extended later. The metadata of the legacy format is also
kept for backward compatibility.

The values of the ro.boot* variables are not part of the image files
and are provided (e.g. by bootloaders) at runtime. Meanwhile, their
values may affect some of the device build properties, as a different
build.prop file can be imported by init during runtime.
This cl adds an option to accepts a list of possible values for some
boot variables. The OTA generation script later use these values to
calculate the alternative runtime fingerprints of the device; and
list the device names and fingerprints in the OTA package's metadata.
The OTA metadata is verified by the OTA server or recovery to ensure
the correct OTA package is used for update. We haven't made any
restrictions on what ro.boot* variables can be used for fingerprint
override. One possible candidate can be the skus listed in
ODM_MANIFEST_SKUS.

This reverts commit b21e48b499.
In practice, some partners use the 'import' statement to override
the device fingerprint at runtime. The runtime fingerprint will
later add to the metadata of OTA package, so that the OTA server
can deliver the package to corresponding devices correctly.
This CL supports parsing a subset of import statement that the init
process recognizes. And we loose the restriction based on how the
dynamic fingerprint is used in practice. Right now, we only searches
for the override of brand, name and device. And the placeholder
format should be ${placeholder}, with its value supplied by the
script caller.
As part of the implementation, we generate all the possible
combinations of the input boot variables. And recalculate the
fingerprint for each of the combination. Though we load the
build.prop multiple times, the logic is easier to follow. Also,
it's more convenient to enhance the logic if we only want to
allow some of the boot variables combination later.

The signature size is needed during payload hashing and signing.
We used to sign the update_engine's payload with RSA keys only. In
this case, the signature size always equals the key size. But the
assumption is no longer true for EC keys, whose DER-encoded signature
size is a variant with a maximum size.
Therefore, we always give the maximum signature size to the delta
generator, who then add paddings to the real signature if necessary.
The maximum signature size is calculated by calling the delta_generator
with the new option '--calculate_signature_size'. For custom payload
signers, we also deprecate the '--payload_signer_key_size' and replace
it with '--payload_signer_maximum_signature_size'.
The EC key in the test is generated with:
The EC key in the unittest is generated with the command:
openssl ecparam -name prime256v1 -genkey -noout -out prime256v1-key.pem
openssl pkey -in prime256v1-key.pem -out testkey_EC.key

This change is part of a topic that moves the recovery resources from the
system partition to the vendor partition, if it exists, or the vendor directory
on the system partition otherwise. The recovery resources are moving from the
system image to the vendor partition so that a single system image may be used
with either an A/B or a non-A/B vendor image. The topic removes a delta in the
system image that prevented such reuse in the past.
The recovery resources that are moving are involved with updating the recovery
partition after an update. In a non-A/B configuration, the system boots from
the recovery partition, updates the other partitions (system, vendor, etc.)
Then, the next time the system boots normally, a script updates the recovery
partition (if necessary). This script, the executables it invokes, and the data
files that it uses were previously on the system partition. The resources that
are moving include the following.
* install-recovery.sh
* applypatch
* recovery-resource.dat (if present)
* recovery-from-boot.p (if present)
This change includes the platform build system and release tools changes to
move the recovery resources from system to vendor (or /system/vendor). The
release tools need to know where to generate the recovery patch, and they
discover this from misc_info.txt variable board_uses_vendorimage, which the
platform build system generates.
We remove applypatch from PRODUCT_PACKAGES, but it is added back as a required
module in target/product/base_vendor.mk.
Several release tools rely on the misc_info.txt board_uses_vendorimage variable
to know how to generate and detect the recovery patch.
This change partially removes the --rebuild_recovery flag from the
merge_target_files.py script. The flag will be fully removed in a follow-on
change.

Instead of relying on META/{system,vendor}_{manifest,matrix}.xml
and blindly copy compatibility.zip from target files package to
OTA package, do a static check on the input target files package
before generating the OTA package.
META/{system,vendor}_{manifest,matrix} does not contain ODM manifest
fragments, which is incorrect.
Also, the on-device check of compatibility.zip uses a old libvintf
binary on the device, which may not understand the incoming VINTF
metadata. This change removes the on-device check. Hence, it removes
the requirement of forwards compatibility of libvintf.
This behavior can be skipped with --skip-compatibility-check.
