This patch eliminated from the _SHARED_ segment of the scoreboard all

  This patch eliminated from the _SHARED_ segment of the scoreboard all
  pointer math.  This is required for portable scoreboards.

  vhost becomes the 'vhost name string' so it now survives ap_generation
  clicks.  next was apparently never used.

  This patch also accounts for the changes to the apr_shm api, and gives
  Win32 the magic of a shared scoreboard.

  Breakage aplenty on non-win32 platforms, I suspect, but this radical
  surgery, and culling of unused functions, was really, really needed.
