Lists of libraries in between the linker namespaces are no longer
hard-coded in ld.config.txt, but instead come from Soong.

Test: build 2017 pixel device with BOARD_VNDK_VERSION=current m -j
Test: the device is bootable, basic functionalities (camera, camcorder,
wifi, bt, gps, etc.) work.

For 2016 pixel devices, where VNDK is not fully enforced, move libz back
to LLNDK so that we can pass the CTS without requiring the default
namespace to be isolated.
If we have libz in vndk-sp directory, test_linker_namespaces fails
because /system/lib/vndk-sp/libz.so becomes accessible. In order to make
the lib inaccessible, we have to make the default namespace isolated,
but this can't be done for 2016 pixel devices where VNDK is not fully
enforced. So, we choose to remove /system/lib/vndk-sp/libz.so and keep
the single copy at /system/lib.

This reverts commit f1d3dbc32f.
With the following changes to move /sbin/adbd to /system/bin/adbd,
we don't need this workaround anymore.

(cherry picked from commit 0603ec4294)
The default namespace for system process now becomes isolated, which
means it can load only the libs that are in search.paths and under
permitted.paths.
/system/framework, /system/app, /system/priv-app, /vendor/app, /data,
etc are added to the permitted paths since libart should be able to
dlopen odex files under the locations.
Following directories become unavailable:
/system/lib/vndk
/system/lib/vndk-sp

- Add a method to get the max size of an elf file by reading the
section header offset + size. This will properly map an elf
file embedded into an apk, instead of just mapping in what is done
by the dynamic linker. It does assume that the section headers are
at the end of the elf file.
- Add new tests for the above functionality.
- Update the unwind_symbols tool to take an address for finding a
function instead of dumping the entire symbol table.

We have seen that storing persistent properties in separate files
causes increased boot latency compared to if they were stored in a
single contiguous file.
This change creates a simple format for a contiguously stored property
file, and adds the support for arbitrary characters in the names of
persistent properties, which previously had been restricted. It has a
mechanism for converting older devices to the new format as well.

Clang static analyzer worries that strcpy to a field may overwrites
other fields. Use snprintf() instead.
