they are currently storing.  There is no way we can force them to flush,
but we can advise.  This also adds the code to ap_rflush to use flush
buckets, although it isn't enabled yet.  I will enable it once we remove
buff from the code.  I also removed all calls to ap_rflush that are either
immediately before or immediately after a call to ap_finalize_protocol.
ap_finalize_protocol sends an EOS bucket, which also advises filters to
flush their data, so having both calls right next to each other is
redundant.

  Get rid of an assertion which assumed that HTTP_IN is the filter
  below us.  Some other filter may play the same role.
ap_setup_client_block():
  Get rid of a commented-out hack which was used to allow chunked
  transport encoding of a request body received by mod_cgi[d].
ap_get_client_block():
  Get rid of special handling for zero-length buckets...  The main
  loop handles that fine.

  get dechunking working
  verify that infrastructure for input filters works
    (use existing AddInputFilter directive)

Unlike with my previous patch, ap_get_client_block() saves state between
calls in the core's per-request dir config.

Unlike with my previous patch, HTTP_IN keeps a count of remaining bytes
in the conn_rec.  Code that needs to prod it to deliver a certain amount
of request body plays with conn_rec->remain directly.

doesn't actually do anything useful, it was meant to remove all zero

perfectly fine to not do this, and to just read those buckets along with
the rest of them.

basic design has ap_setup_client_block setting a field in the conn_rec
which tells http_filter how much data is in the body (with chunking this
will represent how much data is in the chunk).  The ap_get_client_block
then calls down the stack with the maximum amount of data that it can
receive back.  When http_filter reads all of the data, it adds an eos
bucket to the end of the brigade.  ap_get_client_block continues to read
data until it gets the eos bucket.  This allows filters to increase the
size of the body data.

pointers are replaced with a global table that allows modules to register
their bucket types.  Those bucket types are then allowed to be used in
the server processing.  This also required removing all direct calls to
those functions.  The ap_bucket type has an index into an array, so in
each ap_bucket_* function, we use that index to find the correct set of
functions.

  http_filter() - this was referencing e->length even though e->length
    is sometimes -1 (if we have to read the socket bucket to get the
    next bit of the request body); now it does e->read() to force a
    socket need if required
  ap_get_client_block() - this was getting a brigade back with the
    desired amount of data (yeah, right) but only copying out the first
    bucket
