Fix minor premature pessimizations in file engine creation
QAbstractFileEngineHandler ctor adds itself once to handler list, dtor
should not try to be any smarter.
Repeatedly calling the global static "constructor" fileEngineHandlers()
could lead to additional overhead while checking for repeated
construction -- that said, compilers can probably figure this one out,
but being explicit shouldn't hurt.
Reduce string manipulation and copying. Also, prefer QStringBuilder to
building strings by hand.
