This allows partially parsing a json object, allowing some parts to be
passed on as strings to another component that does its own parsing
(ex. a pipewire module)
Some special characters like '\v' are encoded using 6 characters, which
currently does not work because the VLA size asumes a maximum of 4 characters
per encoded special character. This patch refactors this logic to avoid using
VLAs at all and encodes the string directly into the builder.
See #471
Similar to wp_spa_json_builder_add_property(), we need to make sure the dst
array in wp_spa_json_builder_add_string() has room for the null character
because builder_add() expects it.

Timeout of 3 seconds is too slow for test-si-standard-link on slower
devices, crank this up with plenty of extra margin. Does not
practically affect running time on faster devices.
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.
See #388
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
* find out if the node supports iec958 or dsd
* use spa_pod_fixate() to get the default format of the node, like p-m-s does
* use _enum_formats_sync() to utilize the param cache, assuming that the node
always has all features enabled (which is always the case when coming from
an ObjectManager that was defined in Lua)
* simplify the activation / deactivation procedure
* configure nodes with unpositioned channels early, as if they were devices
* populate most session item properties from create-item.lua to keep
things more compact and readable
* use a standard naming scheme for the session item properties
* use session item properties instead of node properties in policy-node.lua
* improve policy-node's performance by converting the properties dictionary
less times for each session item
* refactor some policy logic and make things slighly more readable
* change the accepted values for 'context' in wp_si_linkable_get_ports();
use "input" and "output" to keep things clear, because the previous use
of NULL and "reverse" were implying that a node has only one "standard"
direction, but this is complicated for sinks w/ monitors and duplex nodes
* allow using monitors (which are Audio/Sink nodes in fact) as sources
* treat Audio/Duplex nodes as sinks, like p-m-s does
* respect the "stream.capture.sink" property of streams
