The code I added to fix a crash on Linux does not work on Windows or Mac.
I have added a macro to only use the code on Linux.

Mac had a problem casting the pthread_t to an int.
Changed to the code to use pthread_t.

I should have added the define VISIT_THREADS around the Thread pool code.
I have added that so it will only build when the threading is defined.

The thread pool is not ready for Windows and it turns out that Mac has 
some issues with pthread affinity. So I turn off affinity for Mac for now.
Mac has different code to do affinity.

Another change to this code. Now it will not use pthread_self unless
VISIT_THREADS is defined. Also we have the correct code for Mac.
May still need a change to work on Windows. But that will only be
if we do threading on Windows.
