We still support HOST_OS=windows for the SDK host tools cross-builds, but
that's only when USE_MINGW is set when running under linux.

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.

In BBOTA v2, the stash size computation is inaccurate. A stash will be
used only once, so we deduct its size from stashed_blocks right after
its use. However, the stash doesn't actually get freed until being
overwritten by another stash or destroyed at the end of an update. This
leads to OTA failures due to insufficient space on /cache. This CL
changes the BBOTA v2 script to generate an explicit free right after
its use.

This moves all of the date references under build/ to using a single
datetime that can be set manually using BUILD_DATETIME.
It also adds an option, OVERRIDE_C_DATE_TIME, that if set to true, will
redefine __DATE__ and __TIME__ for all C/C++ files so that it matches
BUILD_DATETIME.

When the root directory is included in system, the assumption that
system is mounted at /system breaks down. Redirect /system to /
in that case.

A few properties are stored as links to the files in the out/
directory, which are no longer available when (re)packing from
target_files zip. Redirect those properties to the actual files in
the unzipped directory when repacking.

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'.

file_contexts (specified by SELINUX_FC) is needed both when building
and (re)packaging. We used to use the copy in out/ when building, and
looked for the copy in BOOT/RAMDISK/ when packaging from target_files
zip. With system_root_image enabled, the file_contexts needed for
building and packaging might be different from the one on device. So
we explicitly pack the file as META/file_contexts in target_files zip.
Also refactor out the overriding of selinux_fc property into
common.LoadInfoDict().

dm-verity may touch some blocks that are not in the care_map due to
block device read-ahead. It will fail if such blocks contain
non-zeroes. As a workaround, we mark them as extended blocks and
zero out explicitly to avoid dm-verity failures.

Due to the change in https://lwn.net/Articles/546473/, kernel reserves a
few extra blocks (lesser of 2% and 4096 blocks) on ext4 FS which leads to
OTA update failures. Adjust the size computation if the device has
BOARD_HAS_EXT4_RESERVED_BLOCKS := true.
It amends the last attemp in [1]. Now it computes the used blocks from the
make_ext4fs output, instead of altering its argument.

Build additional images requested by the product makefile.
This script gives the ability to build multiple additional images and
you can configure what modules/files to include in each image.
1. Define PRODUCT_CUSTOM_IMAGE_MAKEFILES in your product makefile.
PRODUCT_CUSTOM_IMAGE_MAKEFILES is a list of makefiles.
Each makefile configures an image.
For image configuration makefile foo/bar/xyz.mk, the built image
file name
will be xyz.img. So make sure they won't conflict.
2. In each image's configuration makefile, you can define variables:
- CUSTOM_IMAGE_MOUNT_POINT, the mount point, such as "oem", "odm"
etc.
- CUSTOM_IMAGE_PARTITION_SIZE
- CUSTOM_IMAGE_FILE_SYSTEM_TYPE
- CUSTOM_IMAGE_DICT_FILE, a text file defining a dictionary
accepted by BuildImage() in tools/releasetools/build_image.py.
- CUSTOM_IMAGE_MODULES, a list of module names you want to include
in the image; Not only the module itself will be installed to proper
path in the image, you can also piggyback additional files/directories
with the module's LOCAL_PICKUP_FILES.
- CUSTOM_IMAGE_COPY_FILES, a list of "<src>:<dest>" to be copied to
the image. <dest> is relativ to the root of the image.
To build all those images, run "make custom_images".
