a62789a505 SCP: Make repeated debug message summarization the default 
The -F debug switch can now be used to avoid the repetitive message
summarization.  This will trade off debug log file size vs CPU cost to
summarize the output.

dc13df7b7b VAX: Set CPU model correctly on each boot 
Previously the CPU model was only being set when the CPU ROM was
implicitly loaded from the internal ROM image at boot time.  Other
loading of ROM code never set the configured model correctly.

484889ea5a TIMER: Changed sim_idle_ms_sleep() to use a mutex which is unique to idling

29a4fb9802 Visual Studio Projects: Assure .git-commit-id.h gets updated correctly 
Some git capable environments on Windows don't honor the installed git
hook scripts in the repository.  Now that, if we're working within a git repo,
we force a working version of git to be installed in the runtime path.  We
leverage that to force a validation of the commit id on each build.
