pool-based memory management used, and SMALLBUF should disappear.

new ftp_handler.

It gets rid of the type= stuff (although it should still work -- netscape
just doesn't provide that).  It also will do an NLST if the RETR fails
(indicating that it might be a directory and not a file), and it uses a
new function (show_dir) that hacks the NLST data to provide links to the
files and directories that are returned.

Add some more useful directives for logging.

%U: the URL path that was requested
%f: the filename.
%P: the PID of the child that served the request (this might be useful
    for tracking the BROKEN_WAIT problem; I dunno.)

It also adds a %{...}n directive that returns the contents of a note
(from the r->notes table). The idea of this is that modules can set
notes with data to be logged. This patch, as an example, has
mod_cookies put its cookie into a note called "cookie". This allows
mod_log_config to log it without having to use a seperate cookie log

Fix for Netscape 2.x keepalive problems. This also removes the HTTP header
flush which was causing TCP slow start/delayed ACK/delayed segment on keepalives,
eating up ~400 ms (1) additional per keepalive connect, plus latency. This
is in essence the previously submitted fix, using BrowserMatch instead of a
dedicated function.
