Opcodes Aggregator Server
#########################

The Opcodes Aggregator Server model is a foundation model defined by the Bluetooth
mesh specification. It is an optional model, enabled with the
:kconfig:option:`CONFIG_BT_MESH_OP_AGG_SRV` option.

The Opcodes Aggregator Server model is introduced in the Bluetooth Mesh Protocol
Specification version 1.1, and is used to support the functionality of processing
a sequence of access layer messages.

The Opcodes Aggregator Server model accepts messages encrypted with the node's device key
or the application keys.

If present, the Opcodes Aggregator Server model must only be instantiated on the primary element.

The targeted server models should be bound to the same application key that is used
to encrypt the sequence of access layer messages sent to the Opcodes Aggregator Server.

The Opcodes Aggregator Server handles aggregated messages and dispatches them to the
respective models and their message handlers. Current implementation assumes that
responses are sent from the same execution context as the received message and
doesn't allow to send a postponed response, for example from a work queue.
