David Brownell <david-b@pacbell.net>: 

Make startup for the various server ports be quiet, unless
debugging is active:  don't emit needless scarey messages.
Update the relevant documentation and its references:

 - For these port commands ... cover the default values;
   convert to @deffn syntax; include their use outside of
   the configuration stage; and alphabetize.

Similar updates to the rest of that small chapter:

 - Highlight that there even *IS* a configuration stage, after
   which some command functionality is no longer available.

 - For GDB commands ... convert to @deffn syntax; alphabetize;
   include a missing command (!); add missing helptext (!) for
   one non-missing command; update relevant cross-references
   and index entries.

used to specify what TCP/IP ports are used, and how GDB should be
supported.

@section Configuration Stage
@cindex configuration stage
@cindex configuration command
When the OpenOCD server process starts up, it enters a
@emph{configuration stage} which is the only time that
certain commands, @emph{configuration commands}, may be issued.
Those configuration commands include declaration of TAPs
and other basic setup.
The server must leave the configuration stage before it
may access or activate TAPs.
After it leaves this stage, configuration commands may no
longer be issued.
@deffn {Config Command} init
This command terminates the configuration stage and
enters the normal command mode. This can be useful to add commands to
the startup scripts and commands such as resetting the target,

@b{NOTE:} This command normally occurs at or near the end of your
openocd.cfg file to force OpenOCD to ``initialize'' and make the
targets ready. For example: If your openocd.cfg file needs to
read/write memory on your target - the init command must occur before
read/write memory on your target, @command{init} must occur before
the memory read/write commands. This includes @command{nand probe}.
