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.

Test: sailfish builds and boots well
Test: lsof shows VNDK-SP libs are loaded from /system/lib/vndk-sp
Test: RenderScript app (CameraScript) runs well

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.

Test: git diff HEAD:rootdir/etc/ld.config.legacy.txt
HEAD^:rootdir/etc/ld.config.txt => 0
Test: sailfish boots (because BOARD_VNDK_VERSION is not set to
'current')

This file describes how loader should set up
default namespace for different kind of binaries.
Note that vendor and some of system binaries are
not yet ready for this config to be enabled - they
rely on libraries they shouldn't be relying upon.
