Jiyong Park a07f3057d0 vendor apk is unbundled
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'.

Test: 2017 pixel devices build and boots to the UI
Test: a vendor apk (e.g. TimeService.apk) works. Turn the airplain mode on.
Set time. Reboot the device. The time is not reset.
Test: 1) set target as 2017 pixel
2) m -j CtsVendorJniTestCases
3) copy the built apk into /vendor/app/CtsVendorJniTestCases
4) reboot / factory reset
5) adb shell am instrument -w android.jni.vendor.cts

Dimitry Ivanov af0264bbe9 Load vendor public libraries to sphal namespace
Load vendor public libraries to sphal namespace
if it exists - preserve old behavior of loading
these libraries to default namespace if sphal
namespace is not present on the device.

Bug: http://b/37410104
Test: cts-tradefed run singleCommand cts --skip-preconditions -m CtsJniTestCases
      on marlin (with enabled sphal configuration) and on angler where ld.config.txt
      is not present.

Dimitry Ivanov 058b2ea8c5 Explicitly enable greylist for classloader-namespaces
The linker no longer enables greylist by default, it
needs to be explicitly enabled by specifying corresponding
flag.

Jesse Hall e7005979c2 dlext_namespace.h: Declare android_get_LD_LIBRARY_PATH
This allows clients creating their own namespace do so by modifying
the default library path, rather than hardcoding it multiple places in
the system.

Zhenhua WANG f2804e5985 Upgrade native bridge to version 3 to support namespace
Native bridge implements namespace related interfaces in version 3.
The namespace semantic here is same as Android dynamic linker's.
Native loader wraps library loading functions of dynamic linker and
native bridge. Thus, Android runtime is able to load native library
of different ISA on one device by calling native loader directly.

Dimitry Ivanov be4ca3afc0 nativeloader: Add Reset capabilities
In the case when VM is restarted all weak references
from the old VM become invalid. In such event NativeLoader
needs to clear the list of classloaders from old VM.

Dimitry Ivanov 4b0e963872 Move list of public libraries to a config file
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.

Dimitry Ivanov d047c925af Added function to explicitly initialize a namespace
This change replaces lazy get-or-create logic for
linker namespaces with the explicit one.

ApplicationLoaders.getClassLoader(..) is now resposible for
the namespace initialization for PathClassLoaders.

Dimitry Ivanov 426799d770 Add PreloadPublicNativeLibraries function
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
public libraries which could be expensive.
