FreeBSD-9 had introduced support for the full set of Unicode characters to the parsing and processing of keymap character tables. This support has been extended to cover the table for accented characters that are reached via dead key combinations in FreeBSD-13.2. New ioctls have been introduced to support both the pre-Unicode and the Unicode formats and keyboard drivers have been extended to support those ioctls. This commit makes the ABI compatibility functions in the kernel optional and dependent on COMPAT_FREEBSD13 in -CURRENT. The kbdcontrol command in -CURRENT and 13-STABLE (before 13.2) has been made ABI compatible with old kernels to allow a new world to be run on an old kernel (that does not have full Unicode support for keymaps). This commit is not to merged back to 12-STABLE or 13-STABLE. It is part of review D38465, which has been split into 3 separate commits due to different MFC and life-time requirements of either commit.
