This is intended to clarify whether surprising zeroing out of HAL
control structures happens to a particular HAL module, or to any
HAL module at random.
Unfortunately, the crash itself can't be prevented as
audioflinger can't work around a HAL outage, and needs to be
restarted anyway.

We still not sure what causes crashes in Device::get|setParam*,
but it seems that it is somehow caused by the fact that the parameters
code is in a separate class with virtual methods, from which
Device class inherits along with IDevice interface.
The workaround is to substitute multiple inheritance with
delegation in Device class. Hopefully this will either eliminate
crashes or make the underlying reasons more clear.
Some of the code got reformatted by clang-format as a presubmit
requirement.

"default" implies using "primary" legacy device module.
This doesn't change anything for binderized mode, because
the server was only registering itself as "sound_trigger.primary",
so it was the only possibility anyways.
Usage of "stub" (debugging) module is still possible
if audioflinger and corresponding services are built with
USE_LEGACY_LOCAL_AUDIO_HAL=true (added makefile check to ensure
that).

Stream objects used to hold a pointer to underlying HAL device
object which they didn't own. Since destruction of server side
objects is asynchronous, it was possible that a Device object
gets destroyed before Stream objects, making all the HAL device
object pointer to become stale.
Fixed by adding a strong reference to Device objects into Stream
objects.

HALs are prohibited from using framework binder, and there is
no equivalent scheduling policy service in hwbinder. Thus, in order

Test: check priority match between audioflinger's and hal's threads
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.

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.

the presentation position to bogus values if the call to the

- remove unused "struct AudioPatch".

To allow genrules with more than one tool, rename the tool property to
tools and make it an array, replace $tool with $(location <label>),
and use $() for other variables for consistency.

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.

Audio HAL service is common to audio, audio effect, sound trigger and
bradcast radio HALs.

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.

Created after hardware/audio_effect.h with the following changes:
- names changed to satisfy HAL style guide;
- defined an interface per effect, an interface method
per command, and getter / setter methods for properties;
- retained methods for executing proprietary commands
and accessing proprietary properties, only to be used
for third-party software effects;
- HIDL vector type is used instead of count / array pairs;
- provider callback changed to be used over RPC;
- 'dump' is method is already defined by generated code.
Note that audio data is currently transferred using AudioBuffers,
which is not effective due to memory copy and HwBinder transaction
involved. The transfer method will be changed to FastMessageQueue.

The following types are not used in HAL and being removed:
- AudioContentType;
- AudioUsage;
- AudioFlagsMask;
- AudioAttributes.
This is in order to reduce synchronization burden and also
allow extending framework without updating HAL.

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.
