Feb.8 Smaller Stacksize

When the LMS regression test didn't have enough space, the Dec.30 Stacksize information was useful.
The eCos stack was reduced from 4098(=800 in hex) to 1536(=600 in hex).
Using the Dec.30 Stacksize info. that's space for :
the 29 minimum eCos variables + 19 more INT spaces.


The avr_ctl thread stacksize was reduced from 2048 to 1312:
the 29 minimum eCos variables + 12 more INT spaces.


The LMS regression test now works with touch sensor, 3 leds, a motor, 1 button test, and 3 buttons pressed in same test case.
