Threading libraries

[Hasso Tepper <hasso@xxxxxxxxx>]

Although having two threading libraries and nice runtime switching 
mechanism between them is nice, there is a problem. If something new 
needs to be implemented in threading library, it needs to be implemented 
in both of them. Even more, there is many functions (most notably 
barriers) implemented in libthread_xu, but not in libc_r making them 
actually unusable.

There is no changes since then except pthread_atfork and I don't see 
anyone working on more either.

I don't think that it's acceptable in long term, so either someone jumps 
in to implement missing stuff in libc_r or we should remove libc_r at all 
(at least in sense of libpthread.so).

Any thoughts?
