For legacy reason, /data/data is a real dir and /data/user/0 is a
symbolic link to it. Overhead for linux kernel to walk through
symbolic link is not negligible. This is unnessary overhead to
carry over. This patch is to make /data/user/0 a a real dir and
make legacy folder /data/data a symbolic link. OTAed system does
not get impacted.

This allows devices to use functionfs for mtp and ptp instead
of the ordinary functions. The property is set regardless of
which function is enabled so mtp and ptp functions will continue
to work.

Test: use mtp with ffs and non ffs devices

VNDK-SP is relocated back to /system partition from /vendor partition,
following the original design.
In addition, the namespace for RenderScript is added. The namespace is
dedicated for loading VNDK-SP libs for RenderScript such as
libRS_internal.so. The reason for having a separate namespace is that
RenderScript requires more permitted paths (/data/*) which should not be
allowed for normal SP-HALs.

Currently zygote is started early for FBE device but update_verifier is run later
which creates a potential risk. This CL ensures update_verifier run before
zygote touches anything within data/ partition. With this change, we also start zygote
early for unencrypted/unsupported encryption state device.

ro.logd.kernel, ro.config.low_ram, ro.logd.timestamp and ro.debuggable
need to be retrieved prior to logd start in order for the service to
behave in a configured manner. Other essential services are also
dependent on these system properties as well, so it just makes sense
to pick them all up first in 'on fs'.

Currently if a process sets the sys.powerctl property, init adds this
property change into the event queue, just like any other property.
The actual logic to shutdown the device is not executed until init
gets to the action associated with the property change.
This is bad for multiple reasons, but explicitly causes deadlock in
the follow scenario:
A service is started with `exec` or `exec_start`
The same service sets sys.powerctl indicating to the system to
shutdown
The same service then waits infinitely
In this case, init doesn't process any further commands until the exec
service completes, including the command to reboot the device.
This change causes init to immediately handle sys.powerctl and reboot
the device regardless of the state of the event queue, wait for exec,
or wait for property conditions.

libui.so is not used by SP-HALs, so it is removed from the list of libs
exposed from the default namespace.
Also, this fixes a warning message "property value is empty" caused by
the automatically removed trailing '/' for the section 'legacy'. Since
the legacy behavior is already implemented by the linker itself, the
behavior doesn't need to specified in ld.config.txt.
Test: marlin/sailfish boots
Test: no warning message is shown

Now, framework process (any process that is executing /system/bin/* or
/system/xbin/*) are started with three namespaces; default, sphal and
vndk.
default namespace is the namespace that is responsible for loading libs
from /system/lib. It can't load libs from other places such as
/vendor/lib. (However, we temporarily open the path since we haven't
finished the system partition cleanup, but will do eventually).
sphal namespace is the namespace where SP-HAL (Same-process HAL) is
loaded. SP-HAL are the only vendor libraries that are allowed to be
loaded inside framework processes. libEGL_<chipset>.so and
android.hardware.graphics.mapper@2.0-impl.so, etc are SP-HALs. When
framework needs to load those SP-HALs, it explicitly loads it from this
namespace using android_get_exported_namespace() and
android_dlopen_ext().
vndk namespace is the namespace for loading vndk-sp (Vendor-NDK for
Same-Process) libs, which is a small set of framework libraries that
SP-HALs can link against. These libraries are compiled for the same
version of Android that the vendor partition is compiled against.
SP-HALs can not use libraries other than vndk-sp and ndk libs.
Membership to vndk-sp and ndk are strictly closed.
Note that in a system, there are two copies of vndk-sp libs. One at
/system/lib and the other at /vendor/lib/vndk-sp. As a result, there can
be two instances of a same library in a process.
Also adds ld.config.legacy.txt which is used on non-Treble devices where
PRODUCT_FULL_TREBLE is not set to true.
Note, this split can be cleaned up further after b/37139976 is solved.
