tcl

Update the "General Commands" (a.k.a. "random stuff") chapter,
and associated chunks of other text:

 - Switch to @deffn and review everything that's documented

 - Improve descriptions of reset events, with reference to
   the setup.tcl code which issues them.

 - Move one zy1000-specific command to that driver's doc.

 - There is no "script" command; remove its doc.

NOTE:  Some things missing from this bit of work are:

 1- Reviewing the code to catch various *missing* functions,
    mostly from "target.c"

 2- Alphabetizing and organizing.  This chapter is a real
    grab-bag with no evident focus or structural principle.

 3- Hole-filling and bugfixing with respect to messaging/logging.
    Example, what principle could possibly justify the tcl command
    output going into the server output/log instead of just the
    telnet session?

 4- Not just for this chapter ... but there should be a section
    with descriptions of all the supported image file formats,
    so every image command can just reference that section.
