All related constants have been prefixed with `NC`, and the old
definitions will be removed for abi3.
The former forms have been deprecated, and will be removed in abi3.
* `notcurses_mice_enable()` and `notcurses_mouse_disable()` replace
`notcurses_mouse_enable()` and `notcurses_mouse_disable()`, which
have been deprecated, and will be removed in ABI3.
