fix: boot fails on ASAN builds with VNDK restriction
templatize ld.config.txt
Make default namespace for system processes isolated
vndk: add vendor/lib(64)/vndk for vendor namespace
Implement system namespace for vendor process
Use the legacy linker namespace configs when target is sanitized
Permit /system/lib/vndk-sp/hw/ for 'sphal' namespace
Add system/${LIB}/vndk to default namespace for vendor.
Add [test] section for /data/[nativetest|benchmarktest]
/data/nativetest[64] processes are running with the new ns config
Fix the bug that caused boot failure on ASAN builds with VNDK
restriciton. The major cause is because incorrect (old) ld.config.txt
was used when the build is sanitized, which prevented the dynamic linker
to find some VNDK libs that only exist in /system/lib/vndk; the old
ld.config.txt does not have the directory in its search paths. So, this
CL fixes the problem by having the same ld.config.txt for both sanitized
and non-sanitizied builds.
Furthermore, ld.config.txt is modified so that dependency to
libclang_rt* libs are redirected to those in /system/lib directory. This
ensures that the sanitizer runtime libs are not dual loaded but are
provided for both platform and vendors.

The default namespace for system process now becomes isolated, which
means it can load only the libs that are in search.paths and under
permitted.paths.
/system/framework, /system/app, /system/priv-app, /vendor/app, /data,
etc are added to the permitted paths since libart should be able to
dlopen odex files under the locations.
Following directories become unavailable:
/system/lib/vndk
/system/lib/vndk-sp

When the vndk is extended by vendor, the libs in vendor/lib(64)/vndk
will override system/lib(64)/vndk libs. Vendor binaries will search
vndk libs in vendor/lib(64)/vndk prior to system/lib(64)/vndk.
Also, remove a workaround for libsdm-color.so

For vendor process default namespace searches as following order:
1. /vendor/lib/(hw|egl), /vendor/lib: Vendor libs + VNDK-vnd-ext
2. /system/lib/vndk-$(ver): VNDK libs
3. /vendor/lib/vndk-sp-$(ver): VNDK-SP-vnd-ext
4. /system/lib/vndk-sp-$(ver): VNDK-SP
and searches system namespace (/system/lib) only for LL-NDK libs.
This configuarion is used only with BOARD_VNDK_VERSION is defined.

The new linker namespace config causes problem when the target is
sanitized: vendor libs which are loaded in the sphal namespace can't
link against to libclang_rt* libs which are in /system/lib directory
because the directory is not allowed for sphal namsapce.
Long-term solution would be installing libclang_rt* to both /system/lib
and /vendor/lib so that vendor libs can link against to the one in
/vendor/lib.
Until the work is done, let's just disable the new linker namespace
config when the target is to be sanitized.

(cherry picked from commit 90a2487776)
We have both system and vendor tests in the same directory
/data/nativetest. Since we can't distinguish system and vendor tests at
runtime, we choose to run all of them with the legacy namespace
configuration where /system/lib and /vendor/lib are both accessible
without any restriction. Furthermore, /system/lib/vndk-sp is added to
the list of accessible directories for tests since some libs (such as
libion.so) exist only in the directory but not in /system/lib.
This will change in the future when we install system and vendor tests
into different directories (vendor tests goes into ./vendor subdir).
Then, we will run the tests with [system] or [vendor] configurations
depending on their paths.

Native tests under /data/nativetest[64] directory is now running with
the same linker namespace configuration as /system/bin/* processes.
This allows us to stop mimicing the linker namespace configuration of the

- Move the load bias stored out of ElfInterface into Elf. For the compressed
sections, the load bias was not the same as the data from the uncompressed
section.
- Move the initialization of the compressed section into Init. It was too easy
to forget to call the init of the compressed section.
- Do not automatically add in load bias to the pc before calling ElfInterface
code. Do all of the pc manipulations in the Elf object.
- Change the interface GetFunctionName code to pass in the load_bias instead
of modifying the pc inside the code.
- Modify the Step function to pass in the elf offset, not add it to the pc.
It is necessary to have two different relative values when executing the
Step: a pc that is relative to the beginning of the elf for the reading data
the actual instructions when trying to determine if this is in a signal
frame, and a pc that is relative to the map for finding the appropriate
unwind information.
- Add a feature to Unwinder so that an unwind can be stopped if it ends up
in map that has a specified suffix. This is so that the ART unwinding
code doesn't require skipping the compressed section. Instead, stop at
if trying to unwind through a known suffix code that means the code is
in java code. This is important because the compressed section data is
not only used by the jave compiled code, so that will continue to work.
- Fix tests for restructuring, add new tests for new functionality.
Test: Ran art test 137-cfi using new unwinder as default.
Test: Ran new unit tests.

Children of init that use any of the SELinux wrapper functions,
including make_dir(), mkdir_recursive(), and plenty others, need to
first initialize the sehandle with SelabelInitialize().
I wish there were a better solution, but early init doesn't actually
want this handle initialized, so that is a valid use case. Ueventd
needs to initialize this before fork()'ing, so lazy initialization is
not universally acceptable either. Likely we won't have other
children that fork() then exec() init again, so this should be okay.

subcontext_test had been failing due to setexeccon() failing to
transition to vendor_init context. This is a good thing as nothing
other than init should be able to transition into this context.
I don't want to add code to skip the setexeccon() call only for the
tests, so I instead call setexeccon() with the return value of
getcon(). This works however only for root, so these tests are
skipped for non-root.

wait_for_prop sets a flag that prevents the action queue from
continuing while otherwise allowing init's main loop to continue
executing. This cannot be done from a subcontext, so it's moved to
normal init.

property_service is moved out of init.

This lib becomes VNDK-SP just because libutils, which is VNDK-SP, is
depending on it. Since libutils provide android::CallStack class for
collecting and printing the callstack, there is no need for vendors to
use the internal libbacktrace library. Thus the lib is marked as
vendor_available: false.

Previously there is no vboot 1.0 metadata for ENG builds. It relies on
is_device_secure() to query "ro.secure" and skip setting up dm-verity
if the value is 0 (meaning ENG build).
This change will be submitted together with other changes to add vboot
1.0 metadata for ENG builds with a "disable magic". The resulting
metadata will be the same as triggering an "adb disable-verity" on an
USERDEBUG image.
