[luatex] Lua is removing hyperbolic functions

Lua is now in 5.3-work3. It contains three things of possible
importance for LuaTeX:

1. Basic UTF-8 (not Unicode) support.
2. Integer and bitwise arithmetic operators on 64-bit numbers.
3. cosh, sinh, tanh have been deprecated: not in the manual
   but still available through a compatibility option that is
   activated by default.

If any LuaTeX user can give good reasons why the hyperbolic
functions should stay, now is the time to air them on the
Lua mailing list (http://lua.org).
