We have ended up not using them, so let's not carry them
in the ABI of 0.4
We can always revert that, but let's first decide how
these objects should be used
Plugin() is confusing because it's not a constructor, it just finds
an existing instance of a plugin object. All other camel-case
functions are constructors in the current lua API.
Also rename the intermediate lua api table WpDebug -> WpLog
Keeps things more consistent with the function names (wp_log*),
with the lua api (Log.*) and with pipewire using log.{h,c} as well.
After all, these functions are for logging...
This adds WP_SESSION_ITEM_FEATURE_ACTIVE and WP_SESSION_ITEM_FEATURE_EXPORTED
features, so _activate and _export APIs have been removed. Modules and unit
tests have also been updated.
