When outputting audio, the framework issues several HAL calls
from the same thread that writes into data FMQ. These calls
also need to be served on the same thread that writes audio data
to HAL. The same thing happens when audio input is commenced.
Add a command FMQ for passing different commands to the HAL thread.
This way, depending on the calling thread, the same call may go
either via hwbinder or via the command queue.
This dramatically reduces jitter in RTT measurements (although
doesn't improve the latency).

There were two problems:
1. Joining of reader / writer / process threads (the threads that
interact with HAL) was taking up to 1 second because the thread
was usually waiting for an event flag to be toggled, or a 1s
timeout.
2. Calling IStream.close or IEffect.close shouldn't tax the caller.
Changed the code so a call to close only signals the thread that
it's time to exit, and then the thread is only joined in the
effect or stream destructor.

Legacy BT A2DP implementation of Audio HAL may be returning EAGAIN
from get_presentation_position, this is normal and shouldn't be
logged. Otherwise we create logspam as this HAL function is called
often.

Some legacy implementations of the effects HAL use the condition
of the reply buffer being NULL as an indication that they shouldn't
apply attenuation to the input audio data. Therefore, separate
methods are needed to distinguish the use cases of delegating the
volume control to the effect, and just informing the effect of the
volume changes.
A new method added to IEffect: volumeChangeNotification that implements
the second use case. The contract of setAndGetVolume method has been
updated to indicate that it is only called in the first use case.
Also updated the wrapper for a generic IEffect commands to pass NULL
pointers to the command and reply buffers in case when the size
of the input or output data is 0, to preserve compatibility with
direct calls from the framework.

Test: volume control works when both Bass Boost and Equalizer are

The combo call to stream_out->write + get_presentation_position
wasn't delivering the results of these calls entirely
correctly. Since the 'WriteResult' struct was lacking the field
for returning the status of the call to
'get_presentation_position', the client could erroneously update
the presentation position to bogus values if the call to the
legacy HAL had failed.
Updated IStreamOut.WriteStatus to include the missing field,
and updated the code to fill it out.
Also fixed logspam resulting from calling a stubbed
stream_in->get_capture_position.

Translation between audio_offload_info_t and AudioOffloadInfo

Test: play MP3 file with Play Music, check audioflinger dump
audioserver receives a change that makes it to crash once it
detects that audiohal server has crashed (because audioflinger
can't gracefully restore the state of the audio system).
As audioserver.rc file prescribes restaring the audiohal on
audioserver restart, there is no need to rely on the init process
to restart the audiohal. Moreover, asking the init process to do
that causes a double restart of the audiohal service if it crashes.
Test: kill audio-hal process, watch dmesg and logcat

AAC_ADIF, AMR, MP2, FLAC, ALAC, APE, DSD, LDAC.

Several issues addressed:
-- added IDevice.supportsAudioPatches to query whether
create/removeAudioPatch is actually supported by HAL;
-- IStreamOutCallback proxy needs to be owned by IStreamOut
implementation. In order for the client to reset the reference,
added method IStreamOut.clearCallback;
-- IDevice.open{Input|Output}Stream need to return a "suggested" audio
config from HAL;
-- code for converting between system/audio.h and HIDL
data structures has been moved to
android.hardware.audio.common@2.0-util library for reuse;
-- added a workaround for the issue with QC effects HAL trying to write
into the input parameters buffer, which is r/o by Binder design.

Changes made to the .hal definition:
- added missing generated Result for methods implemented via legacy
"command" function;
- fixed Aux Channels feature definition;
- added "size" parameter for reply data in cases where the wrapper
needs to allocate a reply buffer;
- added method for generic support of feature configs;
- added new Result type;
- use arrays instead of strings in effect descriptor to ease
conversion from / to legacy HAL;
- added missing method to the Preset Reverb interface;
- fixed names of the Visualizer enums to avoid clashes with defines
from the legacy HAL file.
The implementation isn't hooked up to the server yet. Need to implement
devices and streams first.

Created after hardware/audio.h with the following changes:
- names changed to satisfy HAL style guide;
- defined getter / setter methods for properties, and interfaces
for devices where needed;
- stream out callback changed to be used over RPC;
- 'dump' method is already defined by BBinder, so in HAL
interfaces it is replaced by 'debugDump'.
Note that audio data is currently transferred using byte buffer,
which is not effective due to memory copy and HwBinder transaction
involved. The transfer method will be changed to FastMessageQueue.

Since in generated C++ code class enums are used, the names of enum
values are scoped anyway, thus carrying the prefix only clutters
code.
For C enums, newly introduced "value_prefix" annotation is used
to add the required prefix.
Added annotations for effects HAL types are just informational,
but can be used would C headers generation ever be required.
Also:
- renamed AudioInputFlags -> AudioInputFlag for consistency;
- moved AUDIO_INTERLEAVE_... constants into their own enum.

The following types are not used in HAL and being removed:
- AudioContentType;
- AudioUsage;
- AudioFlagsMask;
- AudioAttributes.

Test: make
These types are migrated from system/audio.h. The order and syntax
of declarations is preserved where available. The following
changes have been made:
- names changed to satisfy HAL style guide;
- some previously separate enums grouped into one to allow
using values between them (HIDL doesn't allow using values
of one enum in another, and even if it would, that will
probably be incompatible with C++11 enum classes it generates;
- as HIDL doesn't have sizeof, these were substituted with values;
- unions can't contain HIDL string type, thus some names are
expressed as uint8_t arrays;
- "handle" is a reserved word in HIDL;
- HIDL vector type is used instead of count / array pairs;
- obviously, macros and inline functions not migrated.
