Backport from AOSP master.
This enables the Dex pre-optimization for emulator-specific builds.
The idea is to speed up the initial boot sequence of an SDK AVD by
avoiding the costly on-device preopt pass that is performed otherwise
the first time the AVD is launched.
Benchmarking shows reductions in first boot time from 1m30s to 40s
on a 2.4GHz Xeon when emulating the AOSP master ToT.

Backport from AOSP master.
Now that the emulator supports proper ARMv7 emulation, switch to
building all emulator-specific platform images using this instruction
set, in order to benefit from the noticeable speed boost provided by
Thumb-2 instructions.
Note that we don't build with NEON support because emulated NEON
instructions are currently slow, though they work.
IMPORTANT: You need to have the following emulator patch in your tree
in order to start these platform builds easily:

Otherwise, the alternative is to do these things:
1/ Telling the emulator to emulate an ARMv7-A CPU, instead of
an ARMv5TE one. This is normally done with "-qemu cortex-a8"
2/ Using an ARMv7-A capable kernel image, which is available and
usable with -kernel prebuilt/android-arm/kernel-qemu-armv7
Note that the emulator has a special hack that automatically enables
1/ if 2/ is being used (i.e. if the kernel image name ends with -armv7,
then emulate an ARMv7-A CPU automatically).
So in reality, only 2/ is required.

By inheriting from full, this will be more self-maintaining, and
automatically gets a better-configured variant (e.g. it has locales,
a date format, etc...).

This splits the existing full.mk in two parts:
-One is the device-independent full_base.mk
-The other is the emulator-specific device.mk
This way we'll be able to inherit from full_base.mk
for on-device builds without any emulator-specific
files getting in the way.

Use it for the sim build and full build.

A configuration file named audio_effects.conf is now used
to list audio effect libraries and engines to be loaded by the
effects factory. A default version of this file is installed
in /system/etc. OEMs can override this file by placing a file
with the same name under /vendor/etc.
