The change in [1] removed duplicating radio images from RADIO/ to
IMAGES/. When getting the target_files zip for generating secondary
payload, we need to additionally copy the files under RADIO/ over.

BuildInfo already has dict-like getters. This CL adds the matching
setter method to keep it backward compatible with device-specific
scripts that expect a dict.
It also adds items() method that allows iterating the items.

We used to write a fake post-timestamp into package metadata for
"--override_timestamp", which allows a package to be pushed based on
the fake timestamp. This CL stops doing that by using the designated
"ota-downgrade=yes" instead, but keeping the "--override_timestamp" flag
for backward compatibility.
Now both "--override_timestamp" and "--downgrade" allow pushing packages
with downgrade timestamps. The only differenece is that "--downgrade"
enforces a data wiping, because it's intended a real downgrade (based on
Android version or security patch level). "--override_timestamp" serves
the path of a legit "upgrade", but unfortunately with build timestamps
in reverse order (e.g. the two builds are cut from different branches).
With this CL, we write "post-timestamp" to all packages.

ota_from_target_files.py:
Rename PropertyFiles._GetPropertyFilesString to
PropertyFiles.GetPropertyFilesString.
Currently only PropertyFiles.Compute and
PropertyFiles.Finalize gives access to _GetPropertyFilesString.
But Compute force sets reserve_space=True,
and Finalize requires reserved_length.
_GetPropertyFilesString is useful method that can
be used outside releasetools.
One of the usage is in bootable/recovery/updater_sample/.

We've added support in brillo_update_payload that allows additionally
looking for images under RADIO/ in the given target_files zips [1]. This
avoids having duplicate radio images in target_files zips.
Also adjust the unittest in test_ota_from_target_files.py to cover this
path.
As a result of this CL, the radio images will no longer appear in the
image archive (i.e. <target>-img.zip) as well - they are less useful
anyway because we have packed only the _updatable_ pieces that are part
of full bootloader/radio images.

In FinalizeMetadata and PropertyFiles, we need to reserve space between
the calls to Compute() and Finalize(). We used to put a 10-byte
placeholder, in the hope of covering the 'offset:length' space for the
metadata entry, as well as the possible value changes in other entries.
However, this could fail in two possible cases: (a) metadata entry
itself has a large offset (e.g. staying near the end of a 1-GiB package,
where the offset itself has 10-digit); or (b) the offsets for other
entries change substantially due to entry reordering. Note that for case
(b), it's space inefficient to always reserve 15-byte for _each_ token
in the property-files.
This CL handles both of these two cases. For (a), we bump up the 10-byte
to 15-byte, which is large enough to cover a package size up to 10-digit
number (i.e. ~9GiB) with a metadata entry size of 4-digit. All these
15-byte will be used for the metadata token alone.
For (b), we add a fallback flow that would retry one more time, but
based on the already signed package that has entries in desired order.

This CL exposes ota-property-files flag for non-A/B OTA packages.
Currently the line only contains the info for the METADATA entry, for
example "ota-property-files=metadata:69:286". This allows system updater
to just download the METADATA entry, as opposed to downloading the
entire package, to learn about the info regarding the OTA package (e.g.
post-OTA build fingerprint). Note that this requires the OTA server-side
support to pass down the flag along with the update URL.

AbOtaPropertyFiles writes 'ota-property-files' into package metadata.
Comparing to StreamingPropertyFiles, AbOtaPropertyFiles additionally
writes a token of 'payload-metadata.bin' for a virtual entry that's head
of the 'payload.bin'. This entry can be used by the system updater to
verify if a payload is applicable to the underlying device.
AbOtaPropertyFiles intends to replace StreamingPropertyFiles, as it
covers all the info of the latter. We keep them both in P, and will
remove the latter in later release.

This CL breaks down ComputeStreamingMetadata() into mutiple member
functions of StreamingPropertyFiles class, which correspond to the
two-pass logic when generating streaming property files (aka streaming
metadata).
StreamingPropertyFiles.Compute() does the work for the first pass, by
putting placeholders before doing initial signing. Finalize()
corresponds to the second pass, where the placeholders get replaced with
actual data. Verify() can be optionally called to assert the correctness
of the work.
The separation between Compute() and Finalize() is to allow having
multiple StreamingPropertyFiles instances (in coming up CLs). This way
we can call Compute() multiple times for each instance, followed by only
one call to SignOutput(). And similarly for Finalize().

This CL adds a new flag '--skip_postinstall' that allows skipping all
the postinstall hooks when generating an A/B OTA package (default:
False). Note that this discards ALL the hooks, including non-optional
ones. Should only be used if caller knows it's safe to do so (e.g. all
the postinstall work is to dexopt apps and a data wipe will happen
immediately after).

By default, an A/B OTA package doesn't contain the images for the
secondary slot (e.g. system_other.img). Specifying
"--include_secondary" that's introduced in this CL allows generating
a separate payload that will install secondary slot images. Both
payloads will be added to the generated A/B OTA package.
An example A/B OTA package with secondary payload
|
+-- payload.bin
|
+-- payload_properties.txt
|
+-- secondary/payload.bin
|
+-- secondary/payload_properties.txt
|
+-- ...
Such a package needs to be applied in a two-stage manner. During the
first stage, the updater applies the primary payload only. Upon
finishing, it reboots the device into the newly updated slot. It then
continues to install the secondary payload to the inactive slot, but
without switching the active slot at the end (needs the matching support
in update_engine, i.e. SWITCH_SLOT_ON_REBOOT flag).
Due to the special install procedure, the secondary payload will be
always generated as a full payload.

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.
