Change to buckets for isapi output.  Still requires emulation of IO
  Completion/Async behavior, but a non-async REQ_HSE_TRANSMIT_FILE is
  now implemented.

doesn't actually do anything useful, it was meant to remove all zero
length buckets before trying to read from the brigade.  However, it is
perfectly fine to not do this, and to just read those buckets along with
the rest of them.

missing some major pieces that I only found after the commit.  This patch
fixes the problem, and makes sure that request bodies are always ended
with an EOS bucket.

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.

AP_DEBUG is defined.

ap_get_client_block():
. avoid some cases where we leak a temporary bucket brigade
. clean up/fix the logic to copy a brigade into the caller's buffer;
  the wrong length was used in some cases
. add an AP_DEBUG-only assertion for some assumptions made regarding
  the brigade returned by the filters

If ap_get_brigade() returns APR_SUCCESS but an empty brigade, bail out.
Previously, we kept going and sometimes segfaulted while operating on
what we thought was the first bucket.

Free the temporary brigade used by getline().

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.

otherwise, the client doesn't hit EOF on stdin.  Small request bodies
worked without this change (for reasons I don't understand), but large
ones didn't.

  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

specific value, and therefore it belongs in the ap_bucket_file type,
which was also created with this commit.  ap_bucket needs to be as generic
as possible to make it easily extensible, which means we have to keep
the generic ap_bucket type very separate from ap_bucket_foo.

values for the length, -1, 0, and a positive number.  -1 means that the
next filter should return all the data it has, the current filter will
take care to ensure that the protocol is followed.  Most filters will
never use this, because it implies they are implementing a conn_based
input filter.  0 means give me exactly one line of data.  A positive
number means give me a maximum of n bytes.

  I hope this clarifies.  Greg is absolutely correct, there is no need for
  any modules symbol other than AP_MODULE_DECLARE_DATA, since module .h
  files containing imports and exports imply something more sophisticated,
  as the early mod_dav.c example illustrated.

doesn't make much sense to check to see if there is something there.  This
removes the input_data brigade from the conn_rec altogether.  There is no
good reason for a filter to be accessing a bucket brigade from within the
conn_rec.  This shouldn't be here anymore, just like the output_filter
shouldn't be storing the data in the conn_rec.
