Xpra: Ticket #1138: do not map new windows whilst the session is locked

Split from #997. Maybe this should be specific to the win32 client (which may crash otherwise), maybe not.

It is actually quite hard to implement, and as it is things should not crash: we may fail to create an opengl window context but the code should fallback to a non-opengl window in that case.
