Giuseppe D'Angelo 784a290c4b QFileInfo: mark constructors as explicit
These look like leftovers (API flaws).

Construction of QFileInfo from QString (or similar) should be not
implicit, as QFileInfo construction is expensive (might hit the file
system), and this may have users overlook APIs (for instance build a
QFileInfo out of QDirIterator::next(), instead of using ::fileInfo();
using QDir::entryList instead of entryInfoList; etc.).

Leave an opt-out mechanism to ease porting.

Fix a handful of usages around qtbase, with at least a couple of them
likely to be actual "sloppy" code.

[ChangeLog][Potentially Source-Incompatible Changes][QFileInfo] Most
QFileInfo constructors are now explicit. The
QT_IMPLICIT_QFILEINFO_CONSTRUCTION macro is provided to keep old code
working.
