This also whitelists the ro.build.user property, which may change based
on host username.

This changes the build system to provide the signapk tool with the
minSdkVersion of the APK being signed. signapk in turn will then use
SHA-256 instead of SHA-1 if minSdkVersion is 18 (JB MR2) or higher
(see c2c49ed0c1).
To avoid increasing incremental OTA update package sizes for already
released platforms, release build scripts disable the above logic when
signing target files ZIPs for pre-N platforms.

This reverts commit de5bc04717 because it's breaking some builds. Turns out some APKs have multiple sdkVersion attributes returned by aapt.

It calls brillo_update_payload to generate the payload for A/B update.
And packages the payload according to Android OTA package format.
Note that it only supports generating full/incremental OTAs with this
CL. Signing for release may not work properly at the moment.

Modify the number of max blocks per transfer to reduce splitting of
large files during patch generation. This will reduce the size of
final incremental OTA updater package. In specific, the size limit
for each file to transfer is set to 1/8 cachesize instead of a fix
number.

With BOARD_USES_RECOVERY_AS_BOOT = true, we skip building the
non-ramdisk boot.img but building the recovery image as boot.img. It
contains recovery's ramdisk (e.g. with /sbin/recovery). It depends on
the bootloader parameter (skip_initramfs) to determine the actual mode
to boot into.

Add a function check_first_block to read block0 and output a message
on screen if the device has been remounted. The function is called
for version >= 4 only; it executes after a failing block verification
and before recovery attempts.

append2simg can be slow, so generate error correction data before verity
data is appended, and append all metadata to the image at the same time.

This makes the signapk tool use Conscrypt (where possible) instead of
the platform-default JCA providers and the Bouncy Castle JCA provider.
This speeds up (by 10-30%) APK and OTA update signing because
Conscrypt's crypto primitives are backed by BoringSSL.
Previously, the signapk tool consisted only of the signapk.jar.
Because Conscrypt is backed by native code, signapk now consists of
signapk.jar and crypto_openjdk_jni shared library. This requires that
users of the tool be updated to provide a suitable -Djava.library.path
argument to the Java runtime. This change updates all known users of
the tool inside the Android source tree to do so.

We used to silently ignore the return value from apply_patch() even if
it had failed. It gives us more trouble to investigate the failure when
the affected file/partition gets touched in subsequent OTAs. This CL
adds the checking of the return value and aborts the update accordingly.

Add an option "--log_diff <filename>" to ota_from_target_files.py
script. When enabled, it logs the differences between the source
and target builds into <filename> when generating incremental OTAs.
Also move target_files_diff.py into releasetools/ so that it can be
packed into otatools.zip.

The packaging script is broken when we set TARGET_NO_RECOVERY and
SYSTEM_ROOT_IMAGE both. With TARGET_NO_RECOVERY set, we don't have
RECOVERY/RAMDISK/etc/recovery.fstab. It thus fails the assertion in
common.LoadRecoveryFSTab() that "/" must exist in fstab when enabling
SYSTEM_ROOT_IMAGE.

Vendor-specific images (radio, bootloader and etc) used to stay in
RADIO/ in target_files zip. A/B updater expects them to be available
under IMAGES/. Make a copy for such images when calling
add_img_to_target_files.py.
We cannot move them directly from RADIO/ to IMAGES/, because we will
delete everything under IMAGES/ when signing for release.

We can generate a special OTA package that verifies all the partitions
(boot, recovery, system, vendor and etc) on a device. It also calls
device-specific script to verify bootloader and radio images. This
ensures a flashed device contains all the desired images faithfully.
Usage:
ota_from_target_files.py --gen_verify target_files.zip output.zip

Don't generate recovery.img when calling 'make dist' if

[1] changed to use a fixed timestamp for all the generated images
(either the one under $ANDROID_PRODUCT_OUT/ or the one added into the

resync all the files. This CL changes to use a fixed timestamp only when
packaging into the target_files zip.
