Compilation fix for wxUniv/MSW in wxTLW code dealing with menus.

The code used by WM_INITMENUPOPUP and WM_EXITMENULOOP handlers shouldn't be
used in wxUniv build as it's not used there anyhow and doesn't even compile.

Closes #16039.

Don't accept data in unsupported format in wxMSW dnd code.

We wrongly pretended to accept the data in formats which we didn't actually
accept and showed misleading cursors to the user.

Fix this by partially reverting some of the changes of r72668 (see #14697).

Closes #16042.

Fix bug in vertical toolbar size calculation in wxMSW.

Correct the changes of the r76035 to avoid using separators when calculating
the fitting width of the vertical toolbars as this doesn't always work
correctly.

Closes #3788.

Fix initializing bitmaps from DIB in wxMSW code.

Don't call wxDIB::CreatePalette() on an invalid (because its handle had been
detached from it) DIB object.

Also add some comments to explain this code a bit better.

Closes #16045.

Another compilation fix for wxUniv/MSW build.

This should have been part of r76077, see #16039.

Add wxFD_NO_FOLLOW style for wxFileDialog.

This style tells the dialog to return the paths of the link being selected
without dereferencing it.

Currently only implemented under wxMSW as the links are not dereferenced by
default in wxGTK anyhow. But we may want to change this and implement it there
too for consistency in the future.

Closes #15429.

Update the URL of the web site images used in the test.

The old images don't exist any more after web site redesign.

Also, the new favicon can't be loaded from an unseekable stream because it
contains multiple icons, so point to the old favicon instead.

Closes #16049.

Document Insert() and Prepend() overloads taking wxMenu.

Document these methods in addition to AppendSubMenu().

Closes #16052.

Make stretchable spacers work in vertical toolbars too in wxMSW.

Replace the old implementation of stretchable spacers based on changing the
size of the separators used as spacers as the toolbar size itself changed with
a new one, simply replacing the old separator with the new one of the correct
size, as it also works for the vertical toolbars, unlike the old approach.

Closes #13673.

Skip mouse button release events in wxGenericTreeCtrl.

Not doing this prevented the default handling from taking place resulting in
internal confusion in GtkNotebook when wxTreeCtrl was placed inside it: the
code there set the button being held by user in its mouse press event handler
and reset it in its mouse release event handler which was never called because
we didn't skip the event, resulting in ignoring the next mouse press in the
notebook.

Closes #16055.
