Subject: [PATCH 01/29] Don't override Set{Min,Max}Size() in wxWindowQt

This partially reverts commit 3c68696 (Make wxTopLevelWindow::SetSizeHints()
work in wxQt) because it breaks some wxSizer tests. and more importantly, it
breaks the documented behaviour of SetMinSize() which says:

Notice that calling this method doesn't prevent the program from making the
window explicitly smaller than the specified size by calling SetSize(), it just
ensures that it won't become smaller than this size during the automatic layout.

Subject: [PATCH 02/29] Remove newly added functions from wxQt

QtSet{Min,Max}Size() were added for use by Set{Min,Max}Size() and
DoSetSizeHints() overrides. and since we have canceled overriding
Set{Min,Max}Size() in previous commit, there is no need to keep them
around without good reason.

It shouldn't change the insertion point if the value doesn't really change
However, the event should still be emitted in this case as documented.

Subject: [PATCH 18/29] Fix listboxtest test failing under wxQt

Qt uses QString::localeAwareCompare() for comparison and this is what their
documentation says: "On other Unix-like systems without ICU, the comparison
falls back to the system library's strcoll()". Under MSW, Qt uses CompareStringEx()
IOW, Qt always compares strings by locale-specific sorting criteria and BTW
this is what wxGTK was like before this commit 625ed74 (Make sorting of wxListBox,
wxChoice and wxComboBox identical to the MSW sorting)
