Switch vax to timecounters. There are three different clock sources:
- ICR/NICR on most systems (1MHz counter resolution).
- diagnostic timer on KA46/KA48 (1kHz counter resolution, counter is actually
running at around 1024 kHz but is not guaranteed to be monotonic at this
rate).
- 100Hz clock on VXT (nothing but the 100Hz clock interrupt).
Tested on KA49 (ICR style), KA46, KA48 (diagtmr style), VXT2000+ (VXT
{empty,hopeless}ness'r'us style).
