content-length has already been set.  If we don't, then we won't know if
the content-length has changed because some other filter changed the
length of the actual data.  We also ALWAYS want to calculate the content
length if we get the whole brigade in the first call to this function.

if we decided to do so initially *and* we've seen all the data.

Prior to this change, for a http/1.1 request to mod_autoindex, the
unconditional call to ap_set_content_length() gave us the wrong
value (only taking into account the first brigade) and disabled
chunking.

Note that file handle caching is broken (nothing to do with
byte ranges).  mmap caches seem to work o.k.

I continue in case people really hate this.  The patch can be backed out and
all evidence will be removed, but I think this makes maintaining/developing
the code easier in the long term.

This file will need a lot of work as it's using a lot of "raw" information
from socket structures that won't work with IPv6.  Needs to be abstracted out
and use APR instead.

there is still some bogosity in there (huge buffer allocs!), and some
optimizations to be made, but this appears to fix byterange handling.

Acrobat plug-in doesn't like it for some reason.  This does work better
than what we currently have, because at least it returns all of the
requested data.  This basically removes all BUFFs from the byte-range
code and removes all of the byte-range code from the default-handler.

Byte-ranges are now handled by a filter, which makes sense, and it allows
us to handle byte-ranges for all requests, not just files.

signed values in these integers, and we return the error codes directly,
so we should always report the number of bytes read/written correctly.  If
we have an error, that is 0 bytes.  If that is true, then using signed
values doesn't make any sense.

bytes sent to the client correctly.  This also simplifies the
content-length filter a bit, by making it a single pass through the
brigade.

because it didn't signify the end of the brigade, and it didn't signify
the end of a response.  It ended up meaning flush the data, which can be
detemined with bucket type checks.  This also makes the FLUSH and EOS
buckets have a 0 length, which makes a lot of code cleaner, because now we
can just add lengths and be sure they are all >=0.

trace of that possibility from the code.  First of all, there is nothing
that says you can only send one file bucket in a response, and second,
even if a handler sends a file, nothing says that it can't add text before
or after it too.

the first request if this is a keepalive connection.  This allows us to
save the end of the first request until we have enough data from the
second request to make it worthwhile to send the responses.  In order
to do this, we need to allocate mmap's from the connection pool instead
of the request pool.  If we don't use the connection pool, then the mmap
is freed before the data is sent, because the mmap is freed at the end of
the first request.

a flush bucket (e.g., by calling ap_rflush()) if it wants to send a partial
response to the client immediately.
