ff95fb8ec2 SCP: Add warning about reset when RUN command is used multiple times. 
The RUN command implicitly resets all devices which may have unexpected
consequences for a novice user.

The logic now produces a warning about this side effect when more than one
RUN command is executed in the same simulator session.

An explicit RESET command suppresses this warning for a subsequent RUN
command.

A RUN command with the -Q switch also suppresses this warning.

fc3ac62218 TIMER: Fix coscheduling to avoid a 0 delay interval 
When the timer subsystem hasn't gotten fully initialized, devices may
attempt to coschedule schedule events before the clock has gotten
far enough along to be fully initialized.  When this happens we now
make sure to avoid the potential for a zero delay which will may cause
an infinite scheduling loop.

39d2944ede TIMER: Add support for catchup clock ticks and cleaned up asynchronous clocks 
Asynchronous clocks are now built for all simulators which are built with
SIM_ASYNCH_IO defined.  The default behavior has asynchronous clocks
disabled since this is still experimental, but it can be enabled with
SET TIMER ASYNC.

Catchup clock ticks are now available, but since they're experimental,
they aren't enabled by default.  Catchup ticks are only available if the
simulators clock device calls sim_rtcn_tick_ack to acknowledge processing
of clock ticks.  The VAX simulators have been modified to leverage this.
Catchup clock ticks can be enabled with SET TIMER CATCHUP

Additionally, an idle threshold is provided which can be used to
influence when clock calibration may be suppressed.  The default is not
to suppress calibration activities.

The various timer behaviors are visible with the SHOW TIMER command.

The state of the operating timer facilities is visible with: SHOW CLOCK

Timer events which are queued are visible with the SHOW QUEUE command.

32bf2629b1 VAX8600: Changed console input polling 
Polling is now done at least every 500ms even if the prior input
character hasn't been processed yet.   This allows ^E to provide a way
to exit a simulator which otherwise isn't reading from the console port.

2c1cc11485 makefile: Fix to allow compiling with clang on NetBSD 
clang doesn't like the -R option, it wants the long form -Wl,-R. gcc is ok
with either.
clang on OS X doesn't like that form, but the change is only in a
conditional which is relevant when X11R7 is installed and that isn't the
case for OS X.
