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.

added: 117 - Eric Landes patch for introducing the --tcp-keep* options

(http://curl.haxx.se/bug/view.cgi?id=1863171) where he pointed out that
libcurl's date parser didn't accept a +1300 time zone which actually is used
fairly often (like New Zealand's Dailight Savings Time), so I modified the
parser to now accept up to and including -1400 to +1400.

code to instead introduce support for a new proxy type called
CURLPROXY_SOCKS5_HOSTNAME that is used to send the host name to the proxy
instead of IP address and there's thus no longer any need for a new
curl_easy_setopt() option.

The default SOCKS5 proxy is again back to sending the IP address to the
proxy.  The new curl command line option for enabling sending host name to a
SOCKS5 proxy is now --socks5-hostname.

fails, just issue a warning and ignore the failure.

added 116 - bug #1863171, curl_getdate() bug

proxy do the host name resolving and only if --socks5ip (or
CURLOPT_SOCKS5_RESOLVE_LOCAL) is used we resolve the host name locally and
pass on the IP address only to the proxy.
