Add support for SND event framework for helping with notifications among different audio modules/drivers. The SND event framework functions with a master/client mechanism, where each client and the master register with the framework, and then notifies its own status (UP/DOWN). Each master will share a list of clients it is interested in, and once all the clients are registered and notified UP, the framework's state will be UP. On the other hand, as and when any one of the client, or the master reports its state as DOWN while the framework is UP, the framework state would be changed to DOWN, and all clients and the master would be let know about the change.

# Shipment builds (user variants) should not have any debug feature
|
|
# enabled. This is identified using 'TARGET_BUILD_VARIANT'. Slub builds
|
|
# are identified using the CONFIG_SLUB_DEBUG_ON configuration. Since
|
|
# there is no other way to identify defconfig builds, QTI internal
|
|
# representation of perf builds (identified using the string 'perf'),
|
|
# is used to identify if the build is a slub or defconfig one. This
|
|
# way no critical debug feature will be enabled for perf and shipment
|
|
# builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT
|
|
# config.
