The signalling of that a global DNS cache is wanted is done by setting the
option but the setting of the internal variable that it is in use must not be
done until it finally actually gets used!

NOTE and WARNING: I noticed that you can't actually switch off the global dns
cache with CURLOPT_DNS_USE_GLOBAL_CACHE but you couldn't do that previously
either and the option is very clearly and loudly documented as DO NOTE USE so
I won't bother to fix this bug now.

silly code left from when we switched to let the multi handle "hold" the dns
cache when using the multi interface... Of course this only triggered when a
certain function call returned error at the correct moment.

(http://curl.haxx.se/bug/view.cgi?id=1871269) and we could fix his hang-
problem that occurred when doing a large HTTP POST request with the
response-body read from a callback.

their long option names and all descriptions are one-liners.

--keepalive-time to curl to set the keepalive probe interval. I also took
the opportunity to rename the recently added no-keep-alive option to
no-keepalive to keep a consistent naming and to avoid getting two dashes in
these option names. Eric also provided an update to the man page for the new
option.

spanking new CURLOPT_SEEKFUNCTION simply to take advantage of the improved
performance for the upload resume cases where you want to upload the last
few bytes of a very large file. To implement this decently, I had to switch
the client code for uploading from fopen()/fread() to plain open()/read() so
that we can use lseek() to do >32bit seeks (as fseek() doesn't allow that)
on systems that offer support for that.

(it already before skipped /usr/lib).  /usr/lib64 is the default library
directory on many 64bit systems and it's unlikely that anyone would use the
path privately on systems where it's not.

libcurl to seek in a given input stream. This is particularly important when
doing upload resumes when there's already a huge part of the file present
remotely. Before, and still if this callback isn't used, libcurl will read
and through away the entire file up to the point to where the resuming
begins (which of course can be a slow opereration depending on file size,
I/O bandwidth and more). This new function will also be preferred to get
used instead of the CURLOPT_IOCTLFUNCTION for seeking back in a stream when
doing multi-stage HTTP auth with POST/PUT.

(http://curl.haxx.se/bug/view.cgi?id=1868255) with a patch. It identifies
and fixes a problem with parsing WWW-Authenticate: headers with additional
spaces in the line that the parser wasn't written to deal with.

new minimum SSH version support for SCP, SFTP and SOCKS tests.

Some verbosity which still remains, will go out before next release.

authentication failures when using OpenSSH 2.9.9 or SunSSH.

Verified fact: Even when only using publickey authentication,
OpenSSH and SunSSH first validate the user, this implies that
if the user validation fails, 'invalid user', the publickey
authentication will not be allowed to complete.

and the write callbacks that now can make a connection's reading and/or
writing get paused.
