Remove changebar.sty

The changebar.sty file found in the doc directory has questionable
licensing.  In particular, it is not the same changebar.sty found in
CTAN and has no well defined license specified in the file.  Since we
do not actually need changebar.sty, remove it.

-% Change bar document-style option for LaTeX.
-%
-% Copyright (C) 1990 by David B. Johnson.
-
-% These macros draw a solid bar down the right margin of the output,
-% covering a range of the input file that has been declared to be changed.
-%
-% The beginning and end of a change bar in the text are marked with
-% \chgbarbegin and \chgbarend, respectively.  For example,
-%
-%     Here is some sample text \chgbarbegin that was
-%     changed\chgbarend{} and some that wasn't changed.
-%
-% The change bar is drawn continuously between the line of output
-% containing the \chgbarbegin and the line of output containing the
-% \chgbarend.  These lines can end up on separate pages, and the
-% division at page boundaries is handled automatically.
-
-% Two dimensions control the size and placement of the change bars:
-%     \chgbarwidth      The width of a change bar
-%     \chgbarsep        The distance between the text and the change bar
-
-% Warning: it does not appear to be possible to do this completely
-% correctly, due to the time at which the verticle glue on a page is
-% finally set, and the way that page breaks are decided.  With
-% \raggedbottom, this normally works fine.  It hasn't been tested with
-% \flushbottom, but will probably behave worse.  In strange rare 
-% situations, a change bar might be drawn from the first line of a page
-% up off the top of a page; this can usually be fixed by slightly moving
-% the \chngbarend around, or by breaking a single change bar range
-% into two ranges.
