Restore broken win32 build, include apr/std headers before httpd headers

- In httpd we override exit() to trap the true exit code (see os/win32/os.h)
 - process.h was redefining exit() which picked up the macro instead of the
   original exit() declaration
 - Cleaner style pulls in apr, then standard C headers, and finally sets down
   the httpd includes on top of these, resolving the windows build regression
