For file-based OTAs, we used to remove unneeded files in ascending
order, which failed to delete non-empty directories. Reverse the order
to fix the issue.
For example, now we have the following in our generated script:
delete("/system/app/Calculator/arm/Calculator.odex",
"/system/app/Calculator/arm/",
"/system/app/Calculator/Calculator.apk",
"/system/app/Calculator/");

Instead of wrapping a host module definition in 'ifeq($(HOST_OS),...)'
in the Android.mk files, define which hosts are supported using
LOCAL_MODULE_HOST_OS.
A blank LOCAL_MODULE_HOST_OS means that linux and darwin are supported.
A non-empty LOCAL_MODULE_HOST_OS lists the supported HOST_OSs.

For file-based OTAs, symlinks in the source build but not in the target
build will be deleted. However, if a symlink is replaced by a regular
file in the target build, the file will be accidentally deleted when
applying (resuming) the same package again.
Verify the checksum of a symlink that will be unpacked or renamed to.
Delete the file only if it doesn't have the target checksum.

Split large files for BBOTA v3.
Revise stash for BBOTAs when needed.
Assert the stash size when generating OTAs.
Changes in [1] break the backward compatibility of the OTA scripts. Fix

So that we can support building both linux and windows binaries at the

For BBOTA v3, we need to stash source blocks to support resumable
feature. However, with the growth of file size and the shrink of the
cache size, source blocks that represent a file are too large to be
stashed as a whole. CL in [1] solves the issue by replacing the diff
command with a "new" command. However, it may increase the generated
package size substantially (e.g. from ~100MB to ~400MB).
With this CL, if a file spans too many blocks, we split it into smaller
pieces by generating multiple commands. For the same case above, it
reduces the package size to ~150MB.
One potential downside is that after splitting, files like .jar,
.apk and .zip can no longer use imgdiff. We may lose the potential
benefit of using imgdiff for patch size reduction.

(cherry picked from commit 9a5caf2c30)
When generating incremental BBOTAs (v2 and above), we need to ensure
that the needed runtime stash is below the given threshold. If it's
running out of space on /cache, we replace the command that uses a
stash with a "new" command instead.
This may increase the OTA package size, since it is carrying more full
blocks instead of patches. It gets even worse for large files that span
a number of blocks, because currently we will store all the blocks for
the file as "new" blocks if stashing cannot be satisfied. We may further
optimize by splitting them into smaller chunks so that most of them can
still be stashed.

(cherry picked from commit 82c47981bd)
With block-based OTA v2 and v3, it requires stash space on the /cache
partition to back up blocks during an update. We need to ensure that
it doesn't exceed the partition size. Since there might be other files
on /cache as well, we use cache_size * threshold as the maximum allowed
size. The threshold defaults to 0.8, which can be overridden by command
line option '--stash_threshold'.

For squashfs, we currently don't have a system.map. So the whole system
image will be treated as a single file. But for some unknown bug, the
updater will be killed due to OOM when writing back the patched image to
flash (observed on lenok-userdebug MEA49). Prior to getting a real fix,
we evenly divide the non-zero blocks into smaller groups (currently 1024
blocks or 4MB per group).
