We need to use WpSpaJson to parse the values in WpSettings. This is because the
wireplumber configuration is written in JSON, so WpSettings should only hold
JSON values. To fix this, 2 API changes have been done:
- wp_settings_get_int() only accepts gint values, instead of gint64 values. This
is because the WpSpaJson API only parses int values, like spa_json_parse_int().
- wp_settings_get_string() now returns a newly allocated string, this is because
the string needs to be decoded in case it has quotes.
after-events hooks will get the original event triggering it, instead of the
rescan event.
after-events hook can register with any event, but it is called with rescan event
info. This is so because, after-events hook run after all the on-events hooks
are done with and as a part of the rescan event. so it is triggered with rescan
event data, which doesnt carry much info, instead of rescan event, it makes more
sense to call the after-events hook with the original event which triggered it.
- Add a new variable "name" in WpEventHook and use it to log all the
hooks(by name) picked up in _push_event(). This gives a clear picture
if hook is registered for a given event.
- Form a name for an event and a chain of events for an event run, log
both of them. This gives a clear picture of the events executed and
order in which they are dispatched.
- Similarly build hooks chain and print it in _source_dispatch(), this
gives a clear picture of the hooks picked and the order in which they
are dispatched.
- Log only the dispatchable(with hooks) events, this de-clutters
the log messages.
- Monitor to use the JSON APIs and move away from config/lua
- Enhance logic in wpsettings to parse settings which are JSON arrays,
some of the bluetooth properties are JSON arrays and parsing
logic confused them for a rule.
- Add corresponding tests around this logic as well.
- add integer and string version of the APIs,
- Also Refine the APIs, return value to indicate the setting existance
and a new param to return the value of the setting.
- add their lua bindings as well, in lua binding the return value nil
indicates that the setting is not defnied.
- Add corresponding C and lua tests as well.
- Add a few handy debug msgs.
- unlike pipewire, rules will be parsed during the bootup time, i.e
during the creation of the wpsettings object.
- The rules are parsed into the wpinterest objects and stored in the
wpsettings object, they will be eventually used to service the
apply_rule() API.
- Support pipewire syntax of rules defination in this version.
- settings.c tests conf file loading & parsing, metadata updates,
wpsetttings object creation and its API.
- settings.lua tests the API from lua scripts.
- Add a sample settings.conf file, this file contains sections copied
over from client.conf along with the settings section. Add a file
each for wp side and lua side of scripts.
- Make changes in base test infrastructure to take a custom conf file.
- Enhance the wp_settings_get_instance_api() to be take metadata_name
parameter. So, Wpsetttings is now a singleton instance for a given
metadata file.
- Enhance the m-settings module also to be take metadata_name parameter.
this is handy for lua side of tests as its cumbersome to do this is
lua.
This is a tricky case where iteration matches the last 2 objects
managed by an object manager. When we remove them while iterating,
the last object is not removed because it takes the place of the first
upon removal (side-effect of g_ptr_array_remove_fast()) and the iterator
skips it.

This adds three meson options to enable or disable building daemon, tools, and modules.
Building the daemon or tools depends on building the modules, and disabling modules without disabling
the other two will result in meson giving an appropriate error.
These new options will let users skip building and installing unneeded items when they are not needed,
e.g. when only using the C API in another application.
This allows to transparently wait until a link is PAUSED before
returning from the activation transition. This way we can also
catch negotiation/allocation errors while activating a link.
PAUSED is used instead of ACTIVE because ACTIVE depends on the
nodes being activated as well. There are cases where a link may not
activate the nodes (ex, a passive link) and the link may remain
PAUSED for a long time.

Since the string length returned by wp_spa_pod_get_data() does not always match
the size of the actual json object because it is stored in contiguous memory, we
cannot always rely on that API to get the json string data.
The new wp_spa_pod_to_string() always allocates a new string with the same
length as the json size, guaranteeing that the string returned always represents
the json object, regardless of whether it is nested or not. It is always
recommented to use wp_spa_pod_to_string() unless you know what you are doing.
This allows scripts to declare when they have finished their loading,
so we can now also know when wireplumber is done loading and ready to
handle clients

The load functions used to do 3 things:
- push the sandbox function on the stack
- load the file and push it as a function on the stack
- call the sandbox (or the file)
Now there are separate functions to do these 3:
- wplua_push_sandbox
- wplua_load_*
- wplua_pcall
The spa-json parser allows some interesting things to happen, which
are not valid JSON, but we use them for readability in config files...
- The separator may be = or just a space instead of :
- Strings may be unquoted
- Commas may be omitted
