Currently, libBacktraceOffline doesn't try .ARM.exidx if a function
appears in .debug_frame. This make it can't unwind through functions
appear in both .debug_frame and .ARM.exidx, but having dwarf instructions
not accepted by libunwind.
This patch fixes this by trying first .debug_frame then .ARM.exidx on arm.

Test: run libbacktrace_test on arm.

Use a generic check if the address is 32 bits when using the default
formating of a backtrace line instead of an arch check.
Test: New unit tests pass.

Rather than expect exactly one set of maps, make sure there are at
least XX number of maps.
Test: Ran the 32 bit and 64 bit variants of the benchmarks.

The process_vm_read function is much faster than ptrace, but sometimes
that will not work on a remote process. Modify the libunwindstack
MemoryRemote object to figure out which one it can use.
Wrote new unit test to verify this checking behavior.
Modify libbacktrace so that the read from libunwind is used instead of
using the default ptrace calls.
Add some benchmarks to libbacktrace to compare the two different methods.
Test: Ran unit tests libbacktrace/libunwindstack/debuggerd.
Test: Ran debuggerd -b <SYSTEM_SERVER_PID>
Test: Ran debuggerd -b <MEDIACODEC PID>
Test: Ran debuggerd -b <RANDOM_PID>
Test: Used crasher to create tombstones and verified stack data is
Test: dumped properly.

W/T enforce restrictions on linker paths, which M/S do not.
Because of this, media.extractor was unable to load its extractors on W/T.

(cherry picked from commit 593b43910b)
This reverts commit 875fe42a81.
... and fixes a bug that private VNDK libs are not accessible even to
RenderScript framework libraries (such as libRS_internal.so). This is
fixed by exceptionally allowing the private libs only to 'rs'
namespace.

(cherry picked from commit 781c47f4da)
The permitted and search paths should be changed according to VNDK version.
However these paths are fixed with vndk and vndk-sp. So I define the
directory name as below
- /system/${LIB}/vndk${VNDK_VERSION}
- /system/${LIB}/vndk-sp${VNDK_VERSION}
${VNDK_VERSION} will be set by the property "ro.vndk.version".

The dep files are not required because change in the command line
triggers the rule.
Test: m -j ld.config.txt llndk.libraries.txt vndksp.libraries.txt
Re-run the build after adding or removing libs to/from the vndk set.
The txt files are updated accordingly.

Add an ArchEnum to express the arch of the Elf objects and Reg objects.
Split out the regs code into per arch pieces and generic parts.
Also, split out the header files for each arch.
Do not break out the test code yet, there isn't enough and it doesn't
help to maintain the tests.
Test: libunwindstack/libbacktrace/debuggerd unit tests pass.
Test: Running debuggerd -b <PIDS> yields valid data on bullhead.

We already have /etc and /sbin. As the Android world moves towards / being
on the system partition, the circumstances under which a /bin symlink
won't work are reduced. This should already be usable most of the time.
