[svn-r11738] Purpose:

Configure feature

Description:
Added 'make trace' target.

Solution:
Added tracing to 1.7.  This was done automatically in 1.6, but left out
of 1.7 until now (oops!).
Tracing in 1.7 only happens manually, when the user types 'make trace.'
Tracing automatically requires more framework than it's worth.
I also fixed a couple of tracing bugs and ran trace.

Platforms tested:
mir, sleipnir, modi4

Misc. update:
