The <__threading_support> header is a huge beast and it's really difficult to navigate. I find myself struggling to find what I want every time I have to open it, and I've been considering splitting it up for years for that reason. This patch aims not to contain any functional change. The various implementations of the threading base are simply moved to separate headers and then the individual headers are simplified in mechanical ways. For example, we used to have redundant declarations of all the functions at the top of `__threading_support`, and those are removed since they are not needed anymore. The various #ifdefs are also simplified and removed when they become unnecessary. Finally, this patch adds documentation for the API we expect from any threading implementation.
