`is' is now a text symbol (only relevant for dvi). The math variant

can be accessed with `integral'.

* font/devX*/S: Regenerated.
* font/devdvi/generate/texex.map: Remove `is'.
* font/devdvi/EX: Updated.
* font/devhtml/R.proto, font/devutf8/R.proto: Add `integral'.
* font/devlj4/generate/special.map: Ditto.
* font/devlj4/S: Regenerated.
* font/devps/generate/textmap: Add `integral'.
* font/devps/S: Regenerated.

* tmac/dvi.tmac: Define `is'.

* src/roff/troff/glyphuni.cc (glyph_to_unicode_list): Add `integral'.

* src/preproc/tbl/main.cc (process_format): Fix error message.
