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.

append2simg on a large image is fairly slow, so append verity metadata to

Append error-correcting codes to verified partitions provided that
PRODUCT_SUPPORTS_VERITY_FEC is true.
This moves verity metadata to be after the hash tree, and requires

[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
target_files zip). It makes 'adb sync' after 'fastboot flashall' to
resync all the files. This CL changes to use a fixed timestamp only when
packaging into the target_files zip.

A few properties are stored as links to the files in the out/

target_files zip. Redirect those properties to the actual files in
the unzipped directory when repacking.

fs_config function from libcutils, in order to properly set the xattr FS
used to define device specific uid, gid, permissions and capabilities,
now needs TARGET_OUT make variable to be passed explicitly to all tools
using it:
fs_config
fs_get_stats used by mktarball.sh
make_ext4fs used by mkuserimg.sh
mksquashfs used by mksquashfsimage.sh

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".

Added support to build system.img that combines contents of /system and
the ramdisk, and can be mounted at the root of the file system.
To enable this feature, define BoardConfig.mk variable:
BOARD_BUILD_SYSTEM_ROOT_IMAGE := true
Ideally we would just change TARGET_OUT (the path of the staging system
directory) to under TARGET_ROOT_OUT. But at this point many places in
the build system assume TARGET_OUT is independent of TARGET_ROOT_OUT and
we can't make it easily configurable.
Instead this implementation takes the least intrusive approach:
We don't change TARGET_OUT or TARGET_ROOT_OUT. We just assemble a
temporary staging directory that contains contents of both TARGET_OUT
and TARGET_ROOT_OUT, in build_image.BuildImage() of
tools/releasetools/build_image.py.
When build_image.py is directly called from the makefile, we pass in the
parameters from the global dictionary; when build_image.BuildImage() is
called from add_img_to_target_files.py, we need to override values to
point to files extracted from the target_files zip file.
We need to combine the fs_config files of both /system and ramdisk,
when fs_config is enabled.
Also this change refactored build_image.BuildImage() by moving the extra
parameters to the image property dictionary.

A device can set up BOARD_SYSTEMIMAGE_JOURNAL_SIZE (number of journal blocks)
in its BoardConfig.mk.
To disable journaling, set "BOARD_SYSTEMIMAGE_JOURNAL_SIZE := 0".
BOARD_VENDORIMAGE_JOURNAL_SIZE and BOARD_OEMIMAGE_JOURNAL_SIZE work in
similar way.
