This is taken from I6a57a28f22600aafb2e529587ecce6083e9f7da4 and makes
all the needed changes to make phan pass. Seccheck will instead fail,
but since it's not clear how to fix it (and it is non-voting), for the
moment we may merge this and enable phan on IC.

This should fix every error with excluded rules, leaving only the one
for $wgTitle. A double check would be nice in order to avoid regressions
due to stupid mistakes.
