cpu-features: Support 32-bit ARM binaries running on an ARM64 kernel.
This addresses several issues related to 32-bit ARM binaries running
on an ARMv8 CPU.
The first one is that API level 20 exposes getauxval() in <sys/auxv.h>
which provides a reliably way to extract the ARM ELF HwCaps, so try
to use it when possible. Note that this adds -ldl as a LDLIBS
export for the library.
The second one is that /proc/self/auxv should always be the preferred
to /proc/cpuinfo for a process to access the 32-bit ARM ELF HWCaps.
Unfortunately, this file is not always accessible on some recent
Android platform versions, even though this may be fixed in the future.
When the file is not accessible, parse /proc/cpuinfo as a fallback,
but deal with the fact that the 'Features' field only list features
that are optional for the device's CPU reference architecture revision.
I.e. when running on an ARMv8 CPU, it will not list the typical
ARMv7 extensions that became mandatory in ARMv8.
+ Refresh and clarify documentation to explain that the output of
android_getCpuFamily() depends on the process' bitness, not the
target device's CPU.
+ Check that android_getCpuFeatures() returns 0 as expected on
anything except 32-bit ARM and 32-bit Intel.
+ Fix the reporting of ARM IDIV instruction by Goldfish kernels
/ Android emulators.

have very different performance when it comes to FPU or NEON
operations. This can be important for things like JIT compilers.

cpu-features: Add android_setCpu()
This patch adds a new function to the cpu-features library to be able
to set the CPU properties manually, instead of relying on parsing /proc.
This is mostly useful on ARM for sandboxed processes in Android 4.1
and higher, because these don't have permissions to access /proc.

Fix package build errors
This patch fixes two small errors in our release scripts:
- build-gdbserver.sh didn't properly copy the sysroot to the
temporary build directory. Under certain circumstances, this
resulted in a failed build because the destination sysroot
contained symlinks to invalid locations.
- fix two typos in package-release.sh which prevented the script
to actually put any toolchain binaries in the final packages
(doh)
+ Update documentation for upcoming release.

cpufeatures: fix android_getCpuCount() implementation.
This patch fixes the implementation of android_getCpuCount().
The old version did mistakenly parsed /proc/cpuinfo, which only
lists the active cores at a given time. On some multi-core devices,
which enable/disable cores dynamically, calling the function could
result in a value that was lower than the real number of cores.
+ Update the test_cpufeatures.c test to handle ldrex/strex (ARM)
and x86 features.
+ Replace sources/cpufeatures/cpu-features.h with a symlink to
sources/android/cpu-features/cpu-features.h which is the
location of the right header.
