First, thanks for taking over this work. Much appreciated!

The idea in Wayland is to implement the log facility on Weston 
compositor side, which has a total of 190 fprintfs currently. For 
libwayland, as Kristian pointed before [0], we have to make it resilient 
and handle in case of errors instead just spit it to stderr. At the 
moment libwayland-* has 42 fprintfs, which is not much (including 
debugging, that we won't touch).

Anyways, in your patches I've seen that you didn't initialized the log 
facility (wl_log_init); not sure also whether we want wl_log_va in the 
API; and last, I'd remove the WL_LOG_UNKNOWN level, with the intent to 
force the developer think a bit more whenever he/she is coding and 
minimize the output.
