Summary	0005468: Debug rendering like s_drawSounds does not work under com_smp
Description	There are many useful debugging render tools under debug cvars. Some of them don't work under com_smp, some of them force-disable com_smp (see 0004408). Most likely problem is that these debug rendering have lifetime = 0, which means "only render next frame". But with SMP it is broken, and needs fixing.
Steps To Reproduce	1) Start any FM. 2) Enable "s_drawSounds 1". 3) Listen and look for sounds. There should be box and text near every point where sounds originate. It is printed with com_smp 0, but is not with com_smp 1.

So in order to support it properly, some complicated double buffering would be necessary. For now, I'll add s_drawSounds to the condition on disabling com_smp. Also, I guess I'll commit some refactoring of debug geometry drawing (after 2.09 beta is over, I guess). But I'm not sure this issue is worth fixing.
