Fix creating wxGLCanvas without any attributes in wxMSW.

This was broken by the changes of r77018, see #16402.

Just check that we do have the attributes before examining them.

Refactor Unix OpenGL code to avoid using static attributes array.

Put the context attributes in wxGLCanvasX11 itself instead.

See #16402.

Fix handling of identical consecutive key events

Events generated programmatically may have the same timestamp as the previous
event, which caused them to be ignored on the assumption that they were the same
event being sent to a parent window. Fix this by detecting when a new event could
be generated by the event loop.
Closes #15802

Don't exit event loop when exception occurs inside Yield().

If an unhandled exception occurs in an event handler called from Yield(),
don't exit the current event loop which can continue running after handling
this exception in the code calling Yield().

Closes #16419.

Remove default argument value from wxIHTMLElement2::setExpression().

This doesn't make much sense for an interface declaration anyhow and produces
a warning from g++ about assigning string literal to (non-const) BSTR pointer.

Fix generic wxSearchCtrl size/layout code.

Override DoGetBestClientSize() instead of DoGetBestSize(), as we're really
computing just the size of our contents and like this we don't need to hard
code platform-dependent border sizes in this control itself.

Also use the client size in LayoutControls() for the same reason. This also
makes it unnecessary to pass it the width and height as it can find them on
its own. And x and y were never used in the first place, so remove them too.

Finally, center the bitmaps vertically.

Closes #16422.
