Qt: fix a crash when closing application under Windows

QCoreApplication visits eldritch horrors upon argv on Windows. Keep a
local copy for our own processing.

[ Pascal's original comments ]
g6c4ec4a introduced the use of arg_list_utf_16to8 that triggers a crash on my
computer when freeing the g_allocated memory.
Let's do a similar work but with a memory allocator that does not trigger an exception.

Also fix a memory leak in arg_list_utf_16to8 while we are at it.
