Most of these are accidential, obsolete from a time when PHP4 required
these & to enforce passing by reference. This is the default since PHP5.
The issue with this & is that is (in theory) allows hook handlers to
replace the object with an entirely different one. Luckily this does
not work in all cases I'm aware of. But it is confusing, semantically.

This is the default for many years now. Returning true is not different
from returning nothing.
I'm not touching functions that can either return true or false.

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.
