libbacktrace and its dependents are now VNDK-SP. Since they are in
/vendor/lib/vndk-sp directory, they are accessible directly from the
vndk namespace. Therefore, libbacktrace is removed from the exported
shared libs list of the default namespace.

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.

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.

Under full-disk encryption, we must skip extracting libraries
into the temporary /data directory. It is too small, and the
framework will not be able to come up.
Add a check for the vold.decrypt system property. As it turns

(and use 512M = 131072 4K blocks as the limit).

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.

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.

The class early_hal is essentially for the keymaster hal which needs
to be up before vold tries to unlock a storage encryption key (FDE or
FBE). The current position is too early in the boot process, because
on devices with legacy HAL the wrapper service uses system properties
to find the legacy HAL.
This patch moves the start of the early_hal class to the late-fs trigger
action which runs right after the system property action.
Test: Manually tested and update tested on bullhead, sailfish, and
another device.
