Why: the change is done to comply with lilv expectations of hosts. Added call lilv_instance_activate in the config_output function to abide by lilv documentation that states it must be called before lilv_instance_run: "This MUST be called before calling lilv_instance_run()" - documentation source (https://github.com/lv2/lilv/blob/main/include/lilv/lilv.h) Added call lilv_instance_deactivate in the uninit function to abide by lv2 documentation: "If a host calls activate(), it MUST call deactivate() at some point in the future" - documentation source (https://gitlab.com/lv2/lv2/-/blob/main/include/lv2/core/lv2.h) Added instance_activated integer to LV2Context struct to track if instance was activated and only do lilv_instance_deactivate if was activated to abide by lv2 documentation: "Hosts MUST NOT call deactivate() unless activate() was previously called." - documentation source (https://gitlab.com/lv2/lv2/-/blob/main/include/lv2/core/lv2.h) Regarding the patcheck warning (possibly constant :instance_activated): This is a false positive since the struct member is zero-initialized.
