Currently, whether contains patch or verbatim, compute with file size
and patch size.
But ota file must be compressed with zip, so it should be better with
compressed size than uncompressed.

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

Test: Create an incremental with two builds with one of them uses squashfs.

(cherry picked from commit f8acad1480)
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.

Generate a new file containing care_data of system (and vendor)
partition, and add it under META/ of target file package. For
A/B update, copy this file to OTA package for later use by
update_verifier.

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.

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.

* commit '21528c5e053e28cd52d603eded53ffaf36d22637':
releasetools: Only verify the blocks to be touched.
Change-Id: I053c7da789c44916456109c5153f6628fe38c849
For incremental BBOTAs, we used to verify the integrity of all the
blocks in the source partition. In order to reduce the time cost under
recovery, this CL changes to only verify the blocks that will be touched
in the given OTA package (BBOTA >= 3 only). This is a trade-off between
performance and reliability.

This CL fixes the bug in [1] (copy-paste error) and reenables it.
We need to handle a special case that an OTA goes from a source build
without OEM properties to a target build with those properties (or vice
versa). Add support in OTA scripts to deal the case properly, by a)
using two oem_props variables to handle source and target builds
respectively; b) adjusting the fingerprint/thumbprint assertions to
allow a mix of both.

We used to use the update-binary from the target build when creating
incremental OTAs. But for downgrade OTAs, we should use the one in the
source build instead, which is actually newer.

Add --downgrade flag to ota_from_target_files.py script. It allows
generating an incremental OTA that updates from a newer build to an
older one (based on timestamp comparison). "post-timestamp" line in the
metadata file will be replaced by "ota-downgrade=yes". A data wipe will
always be enforced, so "ota-wipe=yes" will also be included in the
metadata file.

The CL in [1] added support for --oem_no_mount. It missed one place that
guards the OEM mounting.
[1] commit 8608cde944
Change-Id: I6ecaa94cd0866e0fd4fc88cb0aa3ebf55cde2968
We may have devices with OEM-specific properties but without an OEM
partition (e.g. the properties might be set by init based on hardware
SKUs). For such devices, we supply --oem_no_mount to skip mounting the
OEM partition in the updater-script. The option is only meaningful when
-o (--oem_settings) is specified.
