feat: log disabling planes without line breaks

Enumerating all planes to be disabled makes the log unnecessary
sparse. Instead just list all planes in a single line.

For that introduce new API function to log something without line
break in the end and adapt the log callback function pointer.

BREAKING CHANGE: log callback function arguments change.
