Jiyong Park 2498e1b1d3 Re-format ld.config.*.txt files
Re-format the files by splitting lines using +=.

Also add /odm/${LIB} where needed.

A few directories that are no longer required are removed from the
search paths and permitted paths.

Test: walleye and sailfish boots to the UI, renderscript, camera,
camcodder, sound, etc. are working.

Alin Jerpelea fa7958e1fb add odm partition to ld.config.legacy
change is needed to be able to load libraries from /odm partition

/odm partition should have the lowest priority so that it can not override
the libraries from /vendor or /system partitions

Test: libraries are loaded ok.

Jiyong Park 450cff4b68 Configure ld.config.txt for SP-HALs
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.

Bug: 34407260
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')
