Create the anonymous namespace only from a non-empty library path.
This is a better heuristic than the current "first-come" one. It
allows creating classloaders that are not directly related to an
app's "main" classloader, that is, do not have any library path.
This is the case, for example, for shared libraries, including
preloaded ones.
Longer-term, the anonymous namespace creation should be made
explicit, so that the framework can have full control.

Passing nullptr as parent namespace to android_create_namespace makes it use
the namespace of the caller as parent, which typically is the runtime
namespace. That in turn causes classloader-namespace to inherit any
libraries in the shared group of the runtime namespace, i.e. any libraries
that have been loaded in it with RTLD_GLOBAL or DF_1_GLOBAL up to that
point.
Let's instead pass the platform namespace from the linker config as fallback
when a parent namespace cannot be found. That is also what happened before
libnativeloader moved into the runtime namespace.

Partners (entities other than AOSP) can expose their own system
libraries which are in /system/lib[64] to Android apps. This can be done
by adding the name of the libs into the files
/system/etc/public.libraries-<companyname>.txt.
There can be multiple of the txt files on a device, which is for the
case that multiple partners contributing to the same system image
have their own set of public libraries.
The public libraries MUST be named as lib<name>.<companyname>.so. This
is to prevent accidental exposure of AOSP-defined system private libs.
Note 1:
<companyname> doesn't need to be the same as the value of the sysprop
ro.product.manufacturer or anything that can be part of a file path.
Note 2:
This feature is not for exposing SoC-specific libs to Android apps. That
is already done by /vendor/etc/public.libraries.txt and is only for
libs in /vendor/lib[64].

For devices where VNDK restrictions are all enforced, vendor apks are
recognized as unbundled; since system partition and vendor partition can
be updated independently from each other.
However, since vendor apks are still bundled in the vendor partition,
they are allowed to do more than ordinaly unbundled apks that are
downloaded and installed to the data partition.
1) /vendor/lib is allowed. So the path is added to the search_paths and
permitted paths of the classloader namespace.
2) LLNDK libs are allowed in addition to the NDK libs. So, LLNDK lib list
from llndk.libraries.txt is added to the list from public.libraries.txt.
3) VNDK-SP libs are allowed. To do so, the classloader namespace is
linked to the 'vndk' namespace where VNDK-SP libs are searched and
loaded from. The list of available VNDK-SP libs is read from
vndksp.libraries.txt file.
4) Name of the namespace is changed to 'vendor-classloader-namespace'
since the namespace is configured differently from the ordinary
'classloader-namespace'.

This change allows applications to share RTLD_GLOBAL
native libraries between namespaces associated with

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
