bsd-user: Minor fixes

These patches have been in my queue pending too long (I have a bunch of others
that haven't been reviewd, but those will be done clsoe to the end of the
release to not get in the way of the release).

The patches align the stack properly on x86_64, implements setting the tb-size
and properly setting the ts_tid for initial threads. They have all been
reviewed.
