0fd7a9e5ef 3B2: Fix for diagnostics timer hang 
Under certain circumstances, the timer resolution in the Version 3
could become coarse enough that very short timer intervals would lead
to an infinite loop of bus errors when running timer firmware
diagnostics.

5a45a835dd AltairZ80: CPU: Properly reset PC. 
After adding the sim_clock_precalibrate_commands, the PC was not zero
at the sim> prompt after loading altairz80.

Set CPU_S to zero in cpu_reset to address this issue.

796a3e1abc AltairZ80: Adds SOL20 and VDM1 devices 
This PR adds support for the Processor Technology VDM-1 display adapter and Sol-20 computer system. The VDM-1 was integrated into the Sol-20 but has been separated out into its own device.

This PR adds the following devices to the AltairZ80 simulator:

VDM1 - Processor Technology VDM-1 display adapter
SOL20 - Processor Technology SOL20 with SOLOS ROMs
SOL20K - SOL20 Keyboard (callback from VDM1)
SOL20T - SOL20 Tape (reads/writes cassette file images)
SOL20S - SOL20 Serial Port (TMXR capable)
SOL20P - SOL20 Printer Port (TMXR capable)

498aedefd5 sigma: Correct recognition of pending DP seek interrupt. 
This corrects an error that caused SIO reject when SIO occured before
a pending seek interrupt on a different device.
 - Move the interrupt pending test from sigma_io.c into each device.
 - Make the sigma_dp.c test a special case that looks for pending
   seek interrupts.
