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].

vndk_package is a phony module that includes ALL VNDK libs found in the
source code. As a result, VNDK libs that were actually not needed for
the device have been installed consuming storage. For example,
/system/lib/vndk/android.hardware.automotive*.so files were installed
even though walleye/taimen do not have automotive HALs.
VNDK libs are now installed by their link time dependencies (i.e. if a
vendor module uses libcutils, then /system/lib[64]/vndk-sp/libcutils.so
is automatically installed.).
By the way, there is a few number of VNDK libs that do not have any
link time dependency from vendor modules. They are always opened via
dlopen. In such cases, the vndk modules are added to `required`
or `LOCAL_REQUIRED_MODULES` of the module that dlopens them.

When ro.vndk.version has a specific VNDK version in it, use the
llndk.libraries.txt and vndksp.libraries.txt files with the version
suffix in the file names.
If ro.vndk.version is "current" or not set, the version suffix will
not be added.
This is to use a proper VNDK snapshot version configuration for a
vendor patition.

Exempt-From-Owner-Approval: build system cleanup
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'.

libutils, libz and libbase are being used as shared lib by many other
modules.
So using their shared lib will reduce total image size.
Size diffs on angler build image are as follows.
libziparchive.so : 103844 -> 41680 (-62164)
libnativeloader.so: 50824 -> 25104 (-25720)

Native bridge implements namespace related interfaces in version 3.

Native loader wraps library loading functions of dynamic linker and

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.

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.
