Fixes to allow Apache to run as a Win95 service... highlights

  main_win32.h : Moved delarations to a header, by request
  ap_listen.h :  References types declared in http_config.h
  http_main.h :  Add the Win32 flavor entry point declaration
  apr.hw :       Cleanup the redundancy department of redundancy 
  win32/proc.c : Double null termination was required here
  
  Everything else should be obvious and isolated to Win32.
  Build files will be committed seperately.
