Fixed bug 3842 - fix SDL_thread.h for emx

Ozkan Sezer

EMX declares _beginthread() / _endthread() in stdlib.h, not process.h.
The attached patch updates the OS/2 case of SDL_thread.h for it. (It
also tidies the unreadable whitespace in win32 case.)
     1 
     2 This is a list of major changes in SDL's version history.
