Most of these changes were previously discussed via private email and
on the list as well. As for the ABI, I don't see the gnu.ver changes
for the __start_thread to _M_start_thread change and
_Thread_data_base rename as well. Also, should we just inline
thread.join and thread.detach to avoid having to export their names?
Not that I think the names are ever going to change but two less
things affecting the ABI seems like a good thing. Not sure about the
rules to determine whats sufficiently trivial and inline-able.
Otherwise, OK with the rest.
