Parallels the commit to apr.h.in/apr.hw for the apache core library.
Only mod_dav/mod_dav_fs and ap_hooks.h (as best examples) will use these
symbols until it is acceptable to all or the new symbols are backed out.
This symbol rename will have the unique quality that
strlen("API_EXPORT") == strlen("AP_DECLARE"), therefore the mass symbol
rename will not throw off function continuation lines.
This one is odd, it's not the patch either of us are concerned with, it's
the logic that they started with. If problems we never knew about just
go away, don't blame us.

The core filter should not be using its own brigade inside its own ctx
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

The newest incarnation of http_filter. This is far from perfect, but it
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.

Fix a potential memory overrun error in ap_get_client_block. The problem
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

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
