LLVM_RELEASE_VERSION is unused from envsetup.sh and during product
config loading. LLVM_PREBUILTS_VERSION is still used in envsetup.sh, so
needs to stay.
Delay reading core/clang/config.mk until after Soong's variables are
read so that we don't need a copy of LLVM_PREBUILTS_BASE.

Add BOARD_VNDK_VERSION and LOCAL_USE_VNDK to specify the version of the
VNDK that will be used globally, and whether to use the VNDK on a module
basis.
If the board is using the VNDK:
* LOCAL_COPY_HEADERS may only be used by modules defining LOCAL_USE_VNDK
* LOCAL_USE_VNDK modules will compile against the NDK headers and stub
libraries, but continue to use the platform libc++.
* LOCAL_USE_VNDK modules will not have the global includes like
system/core/include, but it will use device-specific kernel headers.
This change does not attempt to enforce any linking constraints, that
will come in a later patch.

We are investigating replacing make_ext4fs with the upstream tool mke2fs.
To mitigate the trouble that may arise if the new tool behave differently
compared to the old one, there will be a transition period.
Devices that want to use the new way of creating ext4 images can set the
variable "TARGET_USES_MKE2FS" to true in their BoardConfig.mk
By default, the build system will choose the old tool 'make_ext4fs'.

When dumping make configuration (dump-many-var, dump-var-*), we only
load config.mk, not main.mk. One of the first things that main.mk does
is to include config.mk, so these moves are safe.
Turning off the implicit rules and other make configuration / sanity
checks should happen in all cases, so move them to config.mk
Move dont_bother_rules to config.mk so that it can be used by the ninja

Pruning $(OUT_DIR) can be overaggressive if $(OUT_DIR) matches the name
of any directory in the source tree that contains Android.mk files.
Pruning $(OUT_DIR) is no longer necessary, as one of the first things

This updates the build system for the new Android Verified Boot
codebase. As this is based on Brillo Verified Boot, this change replaces
the existing BVB support.
Android Verified Boot is enabled by the BOARD_AVB_ENABLE variable
BOARD_AVB_ENABLE := true
This will make the build system create vbmeta.img which will contain a
hash descriptor for boot.img, a hashtree descriptor for system.img, a
kernel-cmdline descriptor for setting up dm-verity for system.img and
append a hash-tree to system.img.
Additionally, the descriptors are left in boot.img and system.img so a
third party can create their own vbmeta.img file linking - using the
option --chain_partition - to these images. If this is not needed
footers can be erased using the 'avbtool erase_footer' command. It's
also harmless to just leave them in the images.
By default, the algorithm SHA256_RSA4096 is used with a test key from
the AVB source directory. This can be overriden by the
BOARD_AVB_ALGORITHM and BOARD_AVB_KEY_PATH variables to use e.g. a
4096-bit RSA key and SHA-512:
BOARD_AVB_ALGORITHM := SHA512_RSA4096
BOARD_AVB_KEY_PATH := /path/to/rsa_key_4096bits.pem
To prevent rollback attacks, the rollback index should be increased on a
regular basis. The rollback index can be set with the
BOARD_AVB_ROLLBACK_INDEX variable:
BOARD_AVB_ROLLBACK_INDEX := 5
If this is not set, the rollback index defaults to 0.
The variable BOARD_AVB_MAKE_VBMETA_IMAGE_ARGS can be used to specify
additional options passed to 'avbtool make_vbmeta_image'. Typical
options to be used here include '--prop', '--prop_from_file', and
'--chain_partition'.
The variable BOARD_AVBTOOL_BOOT_ADD_HASH_FOOTER_ARGS can be used to
specify additional options passed to 'avbtool add_hash_footer' for
boot.img. Typical options to be used here include '--hash_algorithm' and
'--salt'.
The variable BOARD_AVBTOOL_SYSTEM_ADD_HASHTREE_FOOTER_ARGS can be used
to specify additional options passed to 'avbtool add_hashtree_footer'
for systems.img. Typical options to be used here include
'--hash_algorithm', '--salt', and '--block_size'.

This was printing "error:", but not actually triggering an error.
Instead of trying to write a single line bash script to handle this,
move the actual check into python. This allows us to print all of the
errors for a single module before triggering the failure.
Also updates the warning format and the warn.py script to properly parse
these warning. Many of the java:sdk -> java:platform warnings are false
positives due to the lack of LOCAL_SDK_VERSION markings on prebuilts.
Individual tags can be marked as warnings now, which lets us check for
system libraries linking against vendor libraries (which won't work on
AOSP). I'm not sure this is a completely valid check, which one reason
that it's just a warning.

Remove the global linker search path, as it can cause spurious build
failures. If a library with the same name as a system library is in the
process of being written to the directory in the global search path, and
the linker may try to read the partially-written built one instead of the
system one. We already use full paths to libraries for target builds,
do the same for host builds. Also remove the normalize library
functions, they are no longer necessary.

soong_zip parallelizes the compression when creating a zip file, which
makes these packaging steps far shorter.
zip2zip skips the decompression and recompression during the -img- file
creation.
For an aosp_arm64-eng aosp/master build:
target_files.zip: 92s to 60s
symbols.zip: 147s to 7s
img.zip: 64s to 0.5s
There's still room to parallelize the image compression during
target_files.zip (add_img_to_target_files step takes most of the time)
