Ensure that only the symbols in liblog.map.txt can be used by the
platform.

libandroidicu is used by various libraries, e.g. libxml2, minikin.
Thus, expose libandroidicu to default namespace.
libpac is only used by libjni_pacprocessor (part of framework).
libicuuc, libicui18n are not exposed to default namespace,
because everyone else, except app, should use libandroidicu.
They are exposed to classloader namespace from runtime namespace
via the work done in libnativeloader in http://r.android.com/887453
b/120786417 has more details about these 2 libraries.

Support netd to load resolv Apex.
Switch namespaces when switching library paths between
/system and the APEX, so that internal library dependencies in both
locations are loaded from their own directory.

Non-treblized devices use ld.config.legacy.txt, which does not
support product partition, leading to access denial from/to product partition.
Declare directly /product since search paths are resolved in linker config.
Test: m -j with non-treblized device upgraded to P.

There has been no section in the linker config file for the binaries
under /postinstall. As a result, the binaries were run with the legacy
default config where /vendor/lib and /odm/lib are added to the search
paths. This is causing selinux denials as the binaries for OTA are not
allowed to access /vendor/lib or /odm/lib, but the dynamic linker calls
realpath(3) on the paths to canonicalize them.
Fixing the issue by letting /postinstall/* binaries to run with a
dedicated linker namespace config, where /vendor/lib and /odm/lib are
not added to the search paths. Not having the paths is okay because
he OTA binaries should not have dependency to the libs there.

Test: do the OTA, selinux denials on postinstall_file is not shown
Test: above test should pass on wahoo, marlin and pre-treble devices

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.

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.

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.
