Patch from Scott McKellar:

1. I moved almost everything from the header file into the
implementation file, since it isn't referenced elsewhere.  All that's
left is one function prototype and a series of nested #includes.

2. I added compilation guards to the header.

3. Except for osrf_prefork_run(), all functions are now static, as is
the child_dead variable.

4. I commented out the MAX_BUFSIZE macro, since it isn't used.

5. I removed the declaration of main(), which seemed rather pointless.

6. I added the const qualifier to the parameters of osrf_prefork_run()
and osrf_prefork_routers().

7. I made sure that all members were explicitly initialized when
creating a prefork_simple or a prefork_child.

8. I commented out both the prototype and the definition of
find_prefork_child(), since we don't call it anywhere.
