  CogVM source as per VMMaker.oscog-eem.2970

Merge VMMaker.oscog-dtl.2968.

Add support for tracing primitives in a single plugin.  The normal 256 element
circular buffer is limited for tracking down plugin bugs because there is so
much noise (context switches, other primitives, etc, etc).  So if the
primTracePluginName is non-nil only calls of primitives within that plugin are
logged (plus a handful of other potentially significant events).  This
successfully traces primitives in e.g. the SoundPlugin:

use via e.g. cogvm -logtrace SoundPlugin myimage.image

Then sending SIGUSR1 one would see something like

primSoundAvailableBytes
primSoundPlaySamples:from:startingAt:
primSoundAvailableBytes
primSoundAvailableBytes
primSoundAvailableBytes
primSoundAvailableBytes

primSoundPlaySamples:from:startingAt:
primSoundAvailableBytes
