Add the ability to check if the pixel format on the current window was
previously set by wglSetPixelFormatWine(), and if was, allow the
application to change it with a regular wglSetPixelFormat call.

Prevent creating a gl_drawable for a window as type DC_GL_WINDOW if
there are known children of the window, since DC_GL_WINDOW does not
support clipping.
Recreate a gl_drawable that was previously create as type DC_GL_WINDOW
when a child is encountered.

This was removed in e75bc6228e, but appears to
mitigate lack of OML_sync_control in at least some setups.

In particular, without WGL_WINE_query_renderer, the only way to determine
whether a particular context version is supported or not is by attempting to
create a context with that version.

The notion that glXSwapBuffersMscOML() with 0/0/0 target_msc/divisor/remainder
is supposed to behave like glXSwapBuffers() with respect to the swap interval
turns out to have been a misconception on my behalf, the extension spec
doesn't actually say that. Adding to the confusion is the fact that some
drivers do in fact behave like that in practice. It's possible to make
glXSwapBuffersMscOML() use the proper swap interval, but it's much easier to
just use glXSwapBuffers() instead. One consequence of the approach taken in
this patch is that child window buffer swaps aren't necessarily synchronised
to vblank, but ultimately that's up to X11DRV_FLUSH_GL_DRAWABLE, not the
buffer swap. This fixes a regression introduced by commit
e75bc6228e.

The swap interval is a property of the GLX drawable, which is destroyed and
recreated by set_gl_drawable_parent() and wglSetPixelFormatWINE(). When that
happens, copy the interval from the old gl_drawable and apply it at the next
call to wglSwapBuffers().
