New stream type: AUDIO_STREAM_ASSISTANT
This is intended to be used by a virtual assistant like
Google Assistant, Bixby, etc.
The audio stream has own volume alias and the volume
does not change by volume changes of other streams.

Enabling and disabling effects when offloaded may not drain
software effects properly as the software effect process
is not called. Make software effect draining more robust.

Add pre processing effect management for concurrent capture scenarii.
When several clients on the same input stream have enabled audio effects,
only the effects attached to the top priotity client are active.
Other effects are suspended.
Add AudioFlinger API to suspend/restore audio effects build on top
of exisiting internal effect suspend mechanism.
RecordThread now supports more than one effect chain.
AOSP pre processing implementation supports more than one effect session
per input.
Refactor AudioPolicyManager::closeAllInputs() to call closeInput() on
all inputs instead of partially duplicated code.

Crash was because of uninitialized (invalid) number of channels.
Initialized channels to default value and ensured
that during set config channel and channel mask value
are updated per the input config.

Instead of rolling our own powerof2 function, use the version provided
by libc. In particular, this version is not ubsan safe, whereas the libc
version is. See https://android-review.googlesource.com/c/platform/bionic/+/932279

This commit adds the following audio capture sources:
- AUDIO_SOURCE_VOICE_PERFORMANCE: for real time live performances like Karaoke.
- AUDIO_SOURCE_ECHO_REFERENCE: for capturing the reference signal to suppress by an echo
canceller. Protected by privileged permission CAPTURE_AUDIO_OUTPUT.
Also added device AUDIO_DEVICE_IN_ECHO_REFERENCE selected when the requested
capture source is AUDIO_SOURCE_ECHO_REFERENCE.

ParsingResult::configPath is the path of the configuration file
used for the factory config parsing.
This path is used for an error log if the configuration file has errors.
The paths used to be a static string literals stored as char*
without lifecycle management.
When it was changed to dynamic strings, the code was not updated.
This patch changes it to a std::string.
