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.

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.

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.

Substantially improves the performance of some BlockImageDiff steps on
large images. GenerateDigraph and AssertSequenceGood are now linear in
the number of blocks in the target image rather than quadratic in the
size of the partition. FindVertexSequence tracks the score of each
vertex, the set of sources and sinks, and maintains a heap for finding
the best vertex to use for the greedy step, instead of repeatedly
re-scanning the set of remaining vertexes.

Add "ota-required-cache" into the metadata file in an OTA package,
which shows the minimum free space on /cache to apply the update.
Add "ota-type" into the metadata file, which shows the OTA type for
this package (i.e. one of FILE, BLOCK and AB).
Also add the cache free space check into updater-script when generating
block-based incremental OTAs (we only had such lines for file-based
incrementals before).

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

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.

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.

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.
