structure.  This changes the core_output_filter to use a brigade inside
the conn_rec.  Think of this as analagous to the BUFF in the conn_rec.
The idea is that if we have pipelined requests, and it isn't worth it to
send the last bit of data from the first request, we want to save that
extra bit of data to the conn_rec, so that the next request sends it
automatically.

  Addresses the huge issue that Crypt::PasswdMD5 is probably not, and
  Digest::SHA1 is possibly not already installed, but the user may not
  even need it for their files!  Also inform the user what to grab and
  where.  Finally, assures that the old Crypt::PasswdMD5 (that didn't
  export apache_md5_crypt()) will work nonetheless.

  There is still one -big- problem ... the list of xDBM_Files options
  won't necessarily correspond to how Apache was built, nor if they
  are using mod_auth_db vs. mod_auth_dbm.  This has -got- to be fixed
  (although it's an old problem.)

is a step in the right direction.  The idea is that the http_filter knows
about the http protocol.  So, it uses that knowledge to discover HTTP
request headers, and sends those headers up to getline.  However, it keeps
the request body saved in it's ctx pointer.

Later, when ap_get_client_block is called, we have set the remaining field
in the conn_rec.  This tells the http_filter how much of the remaining
data is request body, and how much isn't.  So, the http_filter can return
the request body unparsed up throught ap_get_client_block.

This doesn't even try to work with chunked input data, and there are still
some other bugs in it, but it works for small-ish files in my tests, and
it lets other people play with the concept of input filters.  I will try
to play with this more, but others should feel free to hack around in it
too.

begins some work to upgrade the versioning support to some of the more
recent drafts.

- get_resource hook has new params
- create_collection hook no longer takes a pool
- new dav_auto_version_info structure to group up autoversion
  rollback/commit handling data
- new functions for getting workspace, target-selector, etc
- supportedlock hook now takes the resource in question (since different
  resources may have different locks)
- new resource types; tweaks in props.c to support them
- some tweaks with resource creation, Location header, etc.

  Here it is, the Win32 part of the big canonical errors patch.

  The reason is really, really simple.  If we ever choose to mix clib and
  dos error codes, they criss-cross and don't line up, but they share the
  same number space.  As I wrote the new APR_IS_ERROR macros, I realized
  we were about to shoot ourselves in the foot.

  These changes nearly entirely affect Win32 only.  The next big patch will
  affect all of the rv == APR_ENOENT type problems throughout the system.

is that the bucket code does not respect the length passed into it.  This
is correct for buckets, but it means that when we get data out of the
buckets, we may have to split the bucket to make sure that any copy
operations are safe.  We were originally doing the split at the number of
characters read from the bucket, but we really want to do it at the length
of the buffer.

request_rec.  This means that a conn_rec must be supplied when calling
ap_add_filter.  The reason for this change is that we need to be able to
add the core_filter (whether or SSL or not) before we try to read the
request.  This way, if a request fails, we can actually send the error
page back to the client.  With this change, we add the core filter to the
conn_rec during the pre-connection phase.
