Summary
ddcutil primarily uses DDC/CI (Display Data Channel Command Interface) to communicate with monitors implementing MCCS (Monitor Control Command Set) over I2C. Normally, the video driver for the monitor exposes the I2C channel as devices named /dev/i2c-n. Alternatively, there is initial support for monitors (such as Apple displays) that implement MCCS using a USB connection.

app-misc/ddcutil: don't install a removed udev rule
Remove installation of udev rule file that was dropped upstream [1]. Also remove dependency on acct-group/video because it's no longer mentioned in the usb udev rule that still exists [2].

app-misc/ddcutil: add patch to fix build with USE=-X
Upstream added a feature [1] that uses X11 API unconditionally which broke building with USE=-X.

app-misc/ddcutil: fix build error with clang 19
1. 'test STRING' equivalent to '-n STRING' which is True if the length of string is non-zero, so 'test 0' always success. Both 'test ""' and 'test 1 -eq 0' are ok, but the later is more intuitive. 2. too many errors on Wcompound-token-split-by-macro, so disable this warning as a workaround. 3. fix two errors reported by clang 19, patch submitted to upstream.
