Eliminate dependencies on hardware/audio.h (trivial cases)
frameworks/av must not depend on hardware/ (except for the code
from libaudiohal that actually calls into HAL).
This CL deals with simple cases where depending on system/audio.h
is enough.

audio policy: support platforms with no audio devices
Remove requirement to declare an AUDIO_DEVICE_OUT_SPEAKER device
for platforms without audio output.
By convention:
- platforms without audio output should declare a single output
device of type AUDIO_DEVICE_OUT_STUB also declared as default
output device
- platforms without audio input should declare a single input
device of type AUDIO_DEVICE_IN_STUB
Platforms with no audio at all can use stub audio policy configuration
file and audio HAL with the following instructions in device.mk file:
USE_XML_AUDIO_POLICY_CONF := 1
PRODUCT_PACKAGES += \
audio.stub.default
PRODUCT_COPY_FILES += \
frameworks/av/services/audiopolicy/config/audio_policy_configuration_stub.xml:system/etc/audio_policy_configuration.xml

audio policy: fix volume burst on user switch.
Fix two main problems in setStreamVolumeIndex():
1) the conventional initialization or user switch behavior consisting in first
applying volume for AUDIO_DEVICE_OUT_DEFAULT device which resets all volumes
and then apply device specific volumes is problematic: if this is done while
a stream is active, it will temporarily reset the volume to its default
(usually loud) and then back causing an audible glitch.
2) The logic consisting in applying the requested volume to all outputs with a
device selected by the routing strategy corresponding to the requested stream
is problematic: it will cause device specific volumes for other devices than
current one to be applied to active streams.
Restrict the logic to cases of multiple device selections including the
requested device.

audio policy: use reference for all default volume table
This patch migrates all default volume tables as reference
volume tables.
No implicit volume tables is allowed any more, the reference
must be given for all stream type and device category.
It allows removing the WA that was introduce to use the stream CNT
to host the default volume tables.

audio policy: move volume table to XML file
This patch allows to store in XML file volume tables.
The compatibility is maintained for legacy conf file.
Configurable Engine is only compatible with new XML conf.
This patch removes from configurable engine Structure / Settings the volume
table but keep the configurabllity of switching volume profiles from
one another according to criteria like phone state...
(ex: DTMF stream type is following Voice Profile in call)

Audio policy: implement configuration file in XML
This patch introduces configuration file of the policy in XML.
Legacy configuration file is used by default and
compilation flag USE_XML_AUDIO_POLICY_CONF must be defined to
use XML file format.
