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
Fixes#66
Using XDG_RUNTIME_DIR is problematic in test-reserve-device
because GTestDBus also exports XDG_RUNTIME_DIR and then unsets it,
which makes pipewire end up using $HOME for its socket.
Using PIPEWIRE_RUNTIME_DIR is safer, as this variable is only used
by pipewire.
Also use the build directory as a runtime dir (it always exists and
nothing is going to interfere with it) and unset XDG_RUNTIME_DIR from
the CI scripts, since nothing else is using it.
Closes#39
