Forwarded events from voiceagents have their argument JSON as a whole
stuck into a json-c string object which is then used as the outgoing
event argument. The effect is the whole argument JSON is quoted and
unusable until run through a JSON parser on the receiver side. This is
contrary to the vshl-core event documentation and inconvenient for
client implementors, so fix it by tokenizing the internal JSON string
into a json_object tree and passing that as the event argument.

Add support for triggering listening (push-to-talk/PTT) via the
signal-composer "event.voice" event. This enables PTT from the
steering wheel for the CES demo.
Note that this relies on a fix to signal-composer to add the
session context uuid to the replies from event subscribe calls.
Without that, it's not feasible to catch the signal-composer
events with the libappcontroller event scheme and some more
significant rework would be required.

CBL: Code Based Linking in the case of Alexa voice
agent, or more generally Code Based Logging.
It provides a url and code which allows the user to
complete the authorization process and start using
the authorized voice services.
- add subscribeToLoginEvents verb
- add cbl events handling
- include new verb in vshl-core-api.json

Changes include:
- The previous somewhat hard-coded Alexa voiceagent configuration in the
app controller definition has been replaced with a scheme that allows
instead specifying voiceagent configuration via the configuration file
/etc/xdg/AGL/voice-high.json, and individual per-voiceagent
configuration via JSON files in the directory
/etc/xdg/AGL/voiceagents. See the updated README.md for more details.
- The new file reading code for the above change was facilitated by
bumping the C++ standard option to 17 (from 11) to allow use of the
new standard library filesystem classes.
- The configured voiceagents' APIs are now loaded dynamically using the
afb_api_require_api call enabled by the recently exposed
platform:apis:auto-ws widget permission. The widget configuration has
been updated to add the permission, and also remove the previously
hard-code dependency on the "alexa-voiceagent" API.
- App controller event hooks are created dynamically for the events from
the configured voiceagents. This is done by calling back into the
app controller API at the appropriate place during initialization,
replacing the previous hard-coding of events from "alexa-voiceagent".
If future use cases require dynamic removal of voiceagents, then this
scheme will need to be revisited, as the app controller API currently
has no provision for removing events.
- The IAFBApi interdace and AFBApiImpl implementation classes have been
extended with additional getApi and requireApi calls to enable the
above changes in a straightforward manner.

Remove old app-controller submodule usage in favor of library from the
toolchain. Also update dynamic API calls for V3.

Remove old afb-helpers submodule usage in favor of library from the
toolchain. Note that json.hpp is no longer shipped with the library,
and is now assumed to be present in the toolchain, which requires a
DEPENDS addition in the recipe to pick it up, and an #include of
sstream to work with newer versions of json.hpp.

vshl-core: This API is responsible for request arbitration. Verbs exposed are
1. startListening
2. cancelListening
3. subscribe
4. enumerateVoiceAgents
5. setDefaultVoiceAgent Used by applications to subscribe to dialog, connection and auth states of underlying low level voiceagent bindings. Used by applications to trigger voice recognition routine of the underlying low level voiceagent binding.
vshl-capabilities: This API exposes publish and subscribe methods for all the speech framework domains/capabilities. For eg. navigation, phonecontrol etc. This API is used by apps and low level voice agent binding to subscribe and publish these capability messages whenever applicable. The code for this is agl-service-voice-high-capabilities repository.
This specific commit is for vshl-core API.
