Android framework should provide a buffer to the wifihal which needs
to be filled with scan_result. This commit will ensure that would
happen by passing a fixed max buffer size as part of each

1) add the request_id in wifi_get_logger_supported_feature_set
2) Change the wifi_get_firmware_memory_dump API
1) Normally the size of firmware dump is 700KB.
Thus, Driver cannot send the data in one time because of limitation of skb length.
In order to send such big data from kernel Driver,
we need to send data using event continuously until we send the memory dump completely.
In the event handler of hal, it will allocate the
big buffer to store the data.
Once event handler copy the data completely, event handler
will call the function callback(on_firmware_memory_dump).
So, upper layer has to free the buffer after handling the buffer.

Change-Id: I3f8ecce67430bd8270fb157a4e6cd246503a3d9f
Fixes a race condition whereby two requests attempt to change the audio stream
(and interrupt each other). For example, a user space app makes a call through
the audio API and before completion, a kernel function such as jack removal is
detected and is serviced. In this case, you have a nullified audio route that
needs to be re-routed.
In order to know a routing update is needed, a boolean member mForceRouting
has been introduced to enforce routing for the next attempt to set audio output
with a non-null device.

The existing openOutputStream API did not allow passing stream flags even
though its audio hardware interface's open_output_stream counterpart does take
a "flags" argument. This means that, when the audio hw_module is implemented
using libhardware_legacy, the output flag was lost.
This commit adds an API in libhardware_legacy's audio module, allowing to pass
the flag, and updates the default wrapper in order to call this new API instead
of the old version that missed the flag.

Do not allow offloading if one non offloadable effect is enabled. This prevents from
creating an offloaded track and tearing it down immediately after start when audioflinger
detects there is an active non offloadable effect.

Modified getOutput() logic to not systematically
open a new direct output when a profile matches a request.
This causes a problem when transitioning between two
multichannel tracks as the audio HAL will most of the times
only support one direct output stream open at a time.
Instead, reuse an open output if all the parameters match
or force close the output before reopening it.
Also modify releaseOuput():
- close a direct output only if no client is using it anymore
- call closeOutput() instead of removing the output from
the open output list: this factors in code executed when closing an
output stream.

This change makes support for A2DP related audio policy more generic:
-removed WITH_A2DP compilation switch
-use output profile descriptors listing the parameters
(sampling rate, format...) devices and attributes (low power, tunneling...)
for each available output.
All the behavior specific to A2DP is derived from the A2DP output profile
descriptor.
- removed obsolete a2dpUsedForSonification() method.
This is a first step towards a more generic support for different audio
hardware modules (USB, HDMI) and output streams supporting different
combinations of parameters (sampling rate, format...) and attributes
(low power, tunneling...).
Ultimately, the hw modules and output descriptors will loaded from a

There is a bug in the way audio policy manager handles A2DP interface suspend/restore
when SCO is used. This bug is not new but has been triggered by a change in the timing
of the events received by audio policy manager when a call is setup and torn down
introduced by commit 164a8f86c7e48992691368c4895709c3bdb835a4.

The problem is that the code in AudioPolicyManagerBase::checkAndSetVolume() that forces
voice volume to max when setting bluetooth SCO volume is not called if the bluetooth stream
volume did not actually change. So even if we re apply volumes when switching to bluetooth
device, the voice volume is not changed in audio HAL and remains what it was when routed to earpiece.
What makes things worse on Passion is that stream volumes are limited when connected to bluetooth
and their actual value does not change as soon as they exceed the limit threshold.

The noise is the residual ring tone that is still playing while the call is answered and the
audio route changed to headset or earpiece.
The fix consists in muting the ringing tone when changing mode from ringtone to in call
and delaying the route change until the audio buffers are emptied.
First implementations of audio policy manager in Eclair branch have shown that most code is common to all platforms.
Creating AudioPolicyManagerBase base class will improve code maintainability and readability.

gps: Set SUPL server via hostname rather than IP address.
The GPS engine needs the hostname for the secure SUPL case
and deferring the DNS lookup to the HAL might be helpful in the future
if the SUPL server is on a carrier's private network.
