QDirListing: begin() should start iteration from square 0HEADdev

The old behavior was that calling begin() calls
QDirListingPrivate::advance(), if you call begin() again, it would call
advance() a second time. Not the most intuitive of APIs, but it wasn't
any worse/different from QDirIterator Java-style hasNext()/next() (if
you call next() twice, you advance twice).

Now (c)begin() always starts iterating from the very beginning.

pushDirectory(initialEntryInfo) is now called from beginIterating(), so
don't call it in init().

Not using a std::stack because beginIterating() needs to clear the
iterator containers; for some reason on INTEGRITY something like this
won't work (std::stack doesn't have clear()), complaining about the
constructor being explicit:
nativeIterators = {};

The above works just fine on Linux, so instead of having to spell out
the type... just use std::vector directly (back(), pop_back() and
clear()); this is private API so we have full constrol on how the
vectors are used.
