I needed Pthread condition variables for WebKit, so I implemented

them. I have tested this with a simple test program I downloaded
from the internet. We get the same result as on Linux, so I think
this is good. I will test it more with WebKit later.

Our Pthreads implementation is still missing some stuff, but this
adds a good chunk.
