separate from the input filter mode type.

We also no longer look at readbytes to determine the method of
filter operation.  This makes the use of filters more obvious and
allows a wider range of options for input filters modes.

To start with, the new input filter modes are:

AP_MODE_READBYTES (no more than *readbytes returned)
AP_MODE_GETLINE (old *readbytes == 0 case)
AP_MODE_EATCRLF (old AP_MODE_PEEK)
AP_MODE_SPECULATIVE (will be used in a future ap_getline rewrite)
AP_MODE_EXHAUSTIVE (old *readbytes == -1 case)
AP_MODE_INIT (special case for NNTP over SSL)

The block parameter is an apr_read_type_e: APR_BLOCK_READ, APR_NONBLOCK_READ

This also allows cleanup of mod_ssl's handling in the getline case.

error occures because the accept() cannot complete.
You will not see ENOBUFS at 10.20 because the kernel
hides any occurrence from being returned from user space.
ENOBUFS at 11.0 TCP/IP is quite possible, and could
occur intermittently. As a work-around, we are going to
ingnore ENOBUFS.

  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.

- No longer calls exit() when the secret fails to initialize, instead
  post_config just returns !OK and lets the server bail out.

- No longer fails on DSOs -- since we load-unload-reload DSOs we lose
  any static memory that was initialized during the first load.
  This patch allows us to simply pass on the first call to post_config,
  and then do the initialization in the second call.
