With the change in [1], it zeroes out extra blocks that might be read
by dm-verity. We should update the expected number of blocks that get
touched.

For a DataImage, we may have no mapping of ZERO or NONZERO blocks. Don't
write those groups if they are empty.

In BBOTAs if the last block of a DataImage is padded, we should always
write the whole block even for incremental OTAs. Because otherwise the
last block may be skipped if unchanged, but would fail the post-install
verification if it has non-zero contents in the padding bytes.

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.

So that we can support building both linux and windows binaries at the
same time on a linux host. This replaces the ifeq($(HOST_OS),...) checks
in Android.mk files.

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.
