SDS: Clean up CPU modes and record CPU mode in instruction history record
...
The three CPU modes -- normal, monitor and user were represented by two binary flags (nml_mode and usr_mode). The code is simpler and easier to read if the three modes are represented by one three-valued variable, cpu_mode. In addition, record the CPU mode in the instruction history record, and add the mode to the history display.
In addition, add an optional flag to the SET CPU HISTORY=n command to *not* record instructions executed in a particular CPU mode. Flags are -n, -m and -u for normal, monitor and user mode respectively. For example, SET -m CPU HISTORY=n will only record instructions executed in normal or user mode, and will not record instructions executed in monitor mode. This change aids user-mode program debugging by not filling the history with monitor-mode service functions and interrupt activity.

SDS: Further refinement to bootstrap from RAD, update SDS documentation
...
Instead of conditionally compiling in bootstrap support depending upon attached channel, determine dynamically based on RAD's current assignment to channel W or channel E. This allows using "set rad channel=W" for purposes of bootstrapping, and then relocating the RAD with "set rad channel=E" for running a TSS monitor that expects to find the RAD on channel E.

SDS: Allow console bootstrap from RAD if connected to W channel
...
Normally the RAD is connected to the E channel and there is no bootstrap capability (because of hardwired WIM instruction). However, for completeness, add code to allow booting from the RAD if it is connected to the W channel. Add RAD_CHAN definition to define which controller the RAD is connected to.
Improve parentheses in bootstrap code that allows an optional word count (while also permitting the canonical bootstrap sequence).
