Fix @multitable handling in texi2pod.pl

Browse Source 
While trying out Dennis's Armv8.6-A patch, I noticed that texi2pod.pl
didn't handle the new @multitable correctly.  There were two problems:

(1) @multitables nested in other @tables inherited the @item type from
    the enclosing @table.  Since the new @multitable is in a @table @samp,
    we applied @samp markup to the @multitable @items.  This in turn
    meant that it captured the @tab separator in the @item markup.

    Fixed by pushing an empty item code onto the stack.

(2) We didn't handle @headitem.  Fixed by enclosing it in italics,
    like we do for section headings.  This causes it to be underlined
    in the man output.
