For public vendor libraries, a vendor might have only a 32 bit
or only a 64 bit version of the library. Add a way to indicate this
in the public.libraries.txt files. The new format is:
library.so 32
This indicates that this is a 32 bit only public library.
library.so 64
This indicates that this is a 64 bit only public library.

Since linker-namespaces are enabled for all target_sdk_versions
and there is no longer need in workarounds in libnativeloader -
remove unused target_sdk_version parameter for internal calls.
This also brings libnativeloader closer to aosp/master

This change allows applications to share RTLD_GLOBAL
native libraries between namespaces associated with
different classloaders.
The rule is - if a library is GLOBAL within namespace
associated with parent classloader, it is shared
with namespace associated with this classloader
Note that the sharing happens on create_namespace
event, which is tied to createClassloader in case of
application classloaders created by the framework, for
custom application classloaders it is tied to first
loadLibrary() event.

Now that we have the fixed list of whitelisted libraries
there is no longer need to check if java_permitted_path is nullptr.
In fact checking it prevents custom classloaders created by apps
from loading libraries using absolute path.

BaseDexClassLoader the librarySearchPath gets set to null
by java.lang.Runtime.doLoad().
This patch makes nativeloader correctly handle it.

We previously relied on the fact that target sdk version 0
implies system_server, which is not true, target sdk version
may be set to 0 for other apps and it means 1 - the earliest
version of android. This change enables namespaces for
apps targeting all sdk version and for system_server.

This list contains libraries that should directly or indirectly
be accessible to apps for the platform. Note that this list is
not device specific but rather device class specific.
For now we have 2 separate lists; one for Android Phones and Tablets,
and another one for Android Wear devices.

Not all android devices ship with Webview. The requirement of
libwebviewchromium_plat_support.so to be loaded while initializing the
android namespace is therefore liable to cause a crash on devices that
don't support or use Webview. Therefore, this patch makes this
requirement conditional, but enabled by default.
To remove the dependency, device make files should add the following:
TARGET_IGNORE_WEBVIEW_CHROMIUM := true

Shift responsibility of preloading native libraries to the user
of the library. This lets applications that do not use jni but
depend on libnative_loader.so to avoid unnecessary preloads of

InitPublicNamespace and saves memory because

Note that with this change the linker will ignore
icu libraries provided by an app because public
libraries are always provided by system. At this point
it does not affect any apps because before Marshmallow
all of them were getting platform version of icu4c
libs anyways (they will be getting their own copy of the
library only in Marshmallow release).
