libaudiohal: Implement simple HIDL client
This client requires both HIDL client and server to be of the same
ABI version (e.g. 32-bit).
EffectHalHidl::process and EffectHalHidl::processReverse are stubs.
Some extra warnings are logged due to unimplemented functions
in the legacy HAL.

AudioParameter: add functions for working with parameter keys
Added functions that are helpful for building parameter query
strings to be used with HAL's 'get_parameter' methods.

Move TypeConverter into a shared library
This will be needed for the default implementation of the audio HAL
in TREBLE for parsing supported formats etc. provided by HAL in
a form of string literals.
As a bonus, remove some hand-written type conversions in AudioFlinger
used in dumps.
Example changes in the dump output:
HAL format: 0x1 (pcm16) ==> HAL format: 0x1 (AUDIO_FORMAT_PCM_16_BIT)
Processing format: 0x5 (pcmfloat) ==> Processing format: 0x5 (AUDIO_FORMAT_PCM_FLOAT)
Output device: 0x2 (SPEAKER) ==> Output device: 0x2 (AUDIO_DEVICE_OUT_SPEAKER)
Input device: 0 (NONE) ==> Input device: 0 (AUDIO_DEVICE_NONE)
AudioStreamOut: 0x... flags 0x6 (PRIMARY|FAST) ==>
AudioStreamOut: 0x... flags 0x6 (AUDIO_OUTPUT_FLAG_PRIMARY|AUDIO_OUTPUT_FLAG_FAST)
Test: make & run

Brush up audio parameters usage
It is preferred to use the constants from AudioParameter
(which can now serve as an abstraction layer similar to libaudiohal).
Grepped for usages of defines and just string values
and replaced with references to AudioParameter.
Since the parameter definitions are being moved to system/audio.h,
update includes in AudioParemeter and stagefright Utils.

Remove dependencies on hardware/audio_effects.h and EffectsFactoryApi.h
Also remove some outstanding dependencies on hardware/audio.h.
Most of the time, only constants and structs from audio_effects.h
are used, and no actual calls into HAL are made. Move these
definitions into system/audio_effect.h, and generate constants
from TREBLE HAL definition.
For parameters, always use values from AudioParameter class.
There are still some outstanding includes of hardware/audio.h
in code that directly deals with audio modules. Need to extend
libaudiohal interfaces to support required functionality.

strtok stores its values in thread local storage.
So it can not guarantee works well when multithread environment.
AudioFlinger has multithread.
so strtok_r is more safe.

Reduce underruns in screen off, esp. with EQ
Add MonoPipe APIs to specify setpoint.
Use screen state to configure pipe setpoint.
Fix a long-standing bug where pipe sleep time was excessive,
which interacted poorly with governor and low clock frequencies.
Now it deducts the elapsed time since last write(),
which was significant when there was EQ and low clock frequency.

Update AudioParameter
Use definitions for AUDIO_PARAMETER_STREAM_* from <hardware/audio.h>
instead of repeating these constants.
String constants are const char * const.
