Devin Teske 052f89691c Standardize the way functions build their arguments leading up to a dialog 
invocation. Specifically, "top-load" your arguments and in the order in-
which they will be displayed. For example, many [if not all] widgets display
information in the following order, top-to-bottom (visually):

+ backtitle (displayed behind the widget at top-left)
+ title (at the top of the `window')
+ prompt text (just below the title and above whatever widget you choose)
+ Depending on widget, _one_ of the following:
  - menu list
  - radio list
  - check list
  - text input box with initial text
  - [Xdialog(1)] 2x or 3x text input boxes
  - [dialog(1)] a multi-part form
  - progress bar
  - etc. (many more widget choices)
+ buttons (right below the selected widget)
+ [dialog(1)] the hline (displayed at bottom of `window')

NOTE: Xdialog(1) accepts and silently ignores --hline

When building local arguments for your dialog invocation, if the value can't
be cleanly loaded into a local, add "# Calculated below" to the end of the
local declaration while retaining the block order of argument declarations.

Move other local declarations that are not associated with this top-loading
the dialog arguments to right-above where they are first-used.

Also, standardize on the names of the arguments. For example, always use
$prompt (instead of sometimes $msg and sometimes $prompt); use $menu_list
or $shell_list or $radio_list for those respective widgets; ad nauseum.

While we're doing this, flush-out full arguments for many invocations that
were passing NULL strings (making it unapparent if you were staring at this
one invocation what argument that NULL string was supposed to represent).

Last, while we're in startup/rcconf let's remove the unnecessary use of a
GLOBAL (RCCONF_MENU_LIST) for the menu_list.
