Improve portion of the dialog(1) API in dialog.subr responsible for
calculating widget sizes. Instead of forking a sub-shell to calculate the
optimum size for a widget, use a byRef style call-out to set variables in
the parent namespace. For example, instead of:

size=$( f_dialog_buttonbox_size title btitle msg )
$DIALOG --title title --backtitle btitle --msgbox msg $size

The new API replaces the above with the following:

f_dialog_buttonbox_size height width title btitle msg
$DIALOG --title title --backtitle btitle --msgbox msg $height $width

This reduces the number of forks, improves performance, and makes the code
more readable by revealing the argument-order for widget sizing. It also
makes performing minor adjustments to the calculated values easier as
you no longer have to split-out the response (which required knowledge of
ordering so was counter-intuitive).

Centralize standard getopts arguments, both for convenience and to correct
a bug in which certain combinations of arguments produced unexpected results
such as `-dX' (now properly produces debugging and X11), `-XS' (now properly
produces X11 in secure mode), `-df-' (enables debugging when reading a
script from standard-input, etc. Multi-word variations such as `-d -X',
`-X -S', `-d -f-', `-d -f -', etc. also work as expected. Also tested were
variations in argument order, which are now working as expected.

Switch from using a msgbox to display help files to a textbox instead. The
problem with using a msgbox was one of truncation in the case of Xdialog(1)
and lack of screen real-estate (since the msgbox is not scrollable in X11
while a textbox is).

The textbox renders the text much better and is more appropriate for this
type of data display.
