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.

  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.

when SSL needs to flush (e.g. during SSL_accept()) it will call BIO_flush()
which will trigger a call to bio_bucket_ctrl() -> BIO_bucket_flush().
so we only need to flush the output ourselves if we receive an EOS or
FLUSH bucket.

BIO_bucket_flush() and churn_output() had been turning up near the top
of the profile with gprof.  churn_output() of course has now vanished
and BIO_bucket_flush() has dropped, being called far less than before.
