This mode is also supported on the target despite not having the

For dex preopt and JNI library extraction, we should remove the
classes.dex and .so files before we sign the APK so that there
isn't an entry in the manifest.
Prebuilt APKs which are pre-signed will simply not have the files
removed. This may cause some system.img bloat, but signature checks make
this necessary.

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.

The proto handling will modify the set of dependent libraries, but
this was not actually accounted for in dependency handling because
dependencies had already been established.

If LOCAL_WHOLE_STATIC_LIBRARIES contains a library that has
two files that have the same name but are in different
directories, only the first gets included.
This fix detects this case, and uses the m option to ar to force the
duplicate object to the end of the archive. After this, using the p
option gets the correct object file.

In anceint time we didn't have an "sdk" product so that we had to run
"make sdk" in a device product configuration.
Now we have SDK specific product configuration and we don't do "make
sdk" in device product configuration.

The transitive symbol resolving causes build breakage when a binary
has indirect dependency on the NDK library.
We only observed such behaviour in the aarch64 toolchain.

In commit e9dd9f2bf we moved "include $(BUILD_SYSTEM)/android_manifest.mk"
forward before the variable intermediates.COMMON gets defined. That's a
mistake.
This change replaced the tentative variables
package_expected_intermediates_COMMON and guessed_intermediates with
their proper counterparts defined in base_rules.mk.
If their values differ in the two file, that's an error and we should
fix.

- You can give a .aar as source file to a prebuilt static Java library
module. The build system will set up dependencies and rules to extract
classes.jar and other resource files.
- To build against a prebuilt AAR module, use:
LOCAL_STATIC_JAVA_AAR_LIBRARIES := <module names of aar prebuilt AARs>
The build system will set up rules to merge the library's
AndroidManifest.xml with the main AndroidManifest.xml, add the AAR's
resource dirs and link/merge the AAR's classes.jar.

(cherry picked from commit e9dd9f2bfc)
Now libart is the only supported runtime and
we don't need the build variables PRODUCT_RUNTIMES and
DALVIK_VM_LIB.

We use search LOCAL_DPI_VARIANTS in the list of
"$(PRODUCT_AAPT_PREF_CONFIG) $(PRODUCT_AAPT_PREBUILT_DPI)"
and the first takes precedence.
That way if we don't have a best match, we fall back to the second best,
the way how it worked with PRODUCT_AAPT_CONFIG previously.

We had discussed the idea of making all host tools default to using
ASAN. Even if we don't make it the default, this makes it easy for the
user to switch all host binaries over.

Pass -fsanitize=address instead of manually specifying asan libraries
and other linker flags.
Note that we enable LOCAL_ALLOW_UNDEFINED_SYMBOLS by default for host
builds because ASAN only links symbols in the final executable, so
there will _always_ be undefined symbols in intermediate libraries.
