Audio is not cleaned up on shutdown

[madebr]

In S3Shutdown, the descriptors are cleaned up with the following code:

dethrace/src/S3/audio.c

Lines 103 to 113 in 07d5173

	S3Disable();
	for (descriptor = gS3_descriptors; descriptor != NULL; descriptor = next_descriptor) {
	next_descriptor = descriptor->next;
	S3DisposeDescriptor(descriptor->id);
	S3MemFree(descriptor);
	}
	for (outlet = gS3_outlets; outlet != NULL; outlet = next_outlet) {
	next_outlet = outlet->next;
	S3DisposeOutlet(outlet);
	}
	S3DisposeUnboundChannels();

However, S3Disable disables gS3_enabled:

dethrace/src/S3/audio.c

Lines 124 to 126 in 07d5173

	void S3Disable(void) {
	S3StopAllOutletSounds();
	gS3_enabled = 0;

Which causes S3DisposeDescriptor to never do anything:

dethrace/src/S3/audio.c

Lines 193 to 200 in 07d5173

	int S3DisposeDescriptor(tS3_sound_id id) {
	tS3_channel* c; // [esp+Ch] [ebp-10h]
	tS3_outlet* o; // [esp+10h] [ebp-Ch]
	tS3_descriptor* desc; // [esp+14h] [ebp-8h]
	if (!gS3_enabled) {
	return 0;
	}

Applying the following patch to disable S3 after disposal of all descriptors causes infinite recursion:
(the patch is also incorrect, becuase S3Disable stops all outlet sounds before descriptors are destroyed)
