SIC in KIO master

[Harald Sitter]

alohas,

it would appear to me that a recent change in kio [1] was rather,
very, entirely source incompatible (one could argue binary but let's
not go there).

Say I had the following in my application using kio 5.0/1:

connect(copyjob, &CopyJob::aboutToCreate, this, &MyThing::onABoutToCreate);

my application would no longer compile with 5.2 :'(

Can we please revert and deprecate instead?
