Don't crash in wxGridCellAutoWrapStringRenderer when the column is hidden.

Our methods should arguably not be called at all in this case, but if this
does happen, at least don't crash.

Closes #15464.

Simplify wxGridCellAutoWrapStringRenderer::GetBestSize().

The code there was pretty wild, making clearly wrong assumptions (column size
doesn't, and AFAICS never did, include 20 pixel margin) and also was clearly
uncertain about what it was doing by trying to limit the number of iterations
to some arbitrary cutoff when it is pretty clear that the loop increasing the
width and decreasing the height on each iteration will reach the condition of
"width >= height*1.68" sooner or later.

Remove superfluous mouse capturing in wxGrid row/column labels windows.

This code recaptured the mouse in the window which had already had it, thus
triggering the (recently added, see r74677) asserts in CaptureMouse(). It also
didn't preserve the invariant of m_winCapture always having the capture. And
it was apparently completely unnecessary too.

So simply remove it to fix the asserts while drag-resizing wxGrid rows/columns.

Don't take hidden wxGrid row/columns into account when auto-sizing.

The contents not shown to the user shouldn't affect the fitting width/height
of the columns/rows that are shown.

See #15464.

Add wxDEPRECATED_MSG() and use it in a couple of places.

This macro should be used instead of wxDEPRECATED() for the new deprecations
as it allows to give a helpful explanatory message (if supported by the
compiler) and also is simpler to use as it doesn't require wrapping the entire
declaration in it but can be simply used before it.

Also add wxDEPRECATED() support for clang as a side effect.

Add a test for a tooltip for a control inside a static box.

Also create the controls as children of the static box, not its siblings, to
make the tooltip work under wxGTK and because this is how we recommend doing
things now.

See #9859.

Remove unnecessary wxHTML dependency from the notebook sample.

r70321 added html library to the notebook sample, apparently accidentally as
the commit message only mentioned aui one. Remove html and rebake.

Correct erasing of background behind controls in a toolbar in wxMSW.

We need to handle WM_PRINTCLIENT in wxToolBar itself as the default handler
for this message forwards to WM_ERASEBKGND of the parent window and our
handler for that message only erases the client part of the window, in wx
sense, i.e. including a relatively big vertical offset accounting for the
toolbar. This means that when we get WM_PRINTCLIENT from the embedded control
drawing code, we don't erase anything at all as the control rectangle height
is smaller than the offset.

This fix is not perfect as ideally the existing MSWGetBgBrushForChild() should
be taken into account automatically by the default MSWPrintChild()
implementation but at least it fixes the ugly visual artefacts.

Closes #12307.

Restore correct wx-config creation and work around MinGW lack of symlinks.

This undoes the changes of r72205 and r72249 (see #14517) as using relative
paths for wx-config symlink didn't work correctly if non-default values for
$bindir and/or $libdir were used (i.e. if they were not siblings).

Instead, fix the original problem of lack of symlinks when using MinGW
directly: just use "cp -p" if "ln -s" fails. This should work everywhere and
do the right thing.

Closes #15463.
