Limit the number of blocks in command zero to 1024 blocks. This
prevents the target size of one command from being too large and
might help to avoid fsync errors during the OTA update.

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
passed through --replace_verity_keyid. The veritykeyid in the
BOOT/cmdline of input target files is replaced with keyid
extracted from --replace_verity_keyid and written to the
output target files.

It replaces the package verification key (change of path due to
system_root_image flag), as well as the payload verification key.

update_engine now accepts POWERWASH=1 to schedule a factory reset in
the post-install phase. Hook up with the --wipe_user_data flag in the
OTA script.

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.

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.

Modify the abort() function in the OTA update generation script to
report an error code. The recoveryimage will parse the code and write it
into last_install for further data analysis.
