SCP, SFTP and SOCKS4 tests is now OpenSSH 2.9.9 or SunSSH 1.0

For SOCKS5 tests minimum versions are OpenSSH 3.7 or SunSSH 1.0

  decoding where a write error (or abort return from a callback) didn't stop

made it an unsigned int. The type was only used in the curl_sockaddr struct
definition (only used by the curl_opensocket_callback). On all platforms I
could find information about, socklen_t is 32 unsigned bits large so I don't
think this will break the API or ABI. The main reason for this change is of
course for all the platforms that don't have a socklen_t definition in their
headers to build fine again. Providing our own configure magic and custom
definition of socklen_t on those systems proved to work but was a lot of
cruft, code and extra magic needed - when this very small change of type seems
harmless and still solves the missing socklen_t problem.

is an inofficial PROXY4 variant that sends the hostname to the proxy instead
of the resolved address (which is already supported by SOCKS5).  --socks4a is
the curl command line option for it and CURLOPT_PROXYTYPE can now be set to
CURLPROXY_SOCKS4A as well.

function but without a return statement. While fixing that, I also took care
about adding some better comments for the generated code.

(http://curl.haxx.se/mail/lib-2007-12/0252.html) in detect_proxy() which
failed to set the bits.proxy variable properly when an environment variable
told libcurl to use a http proxy.

(http://curl.haxx.se/bug/view.cgi?id=1850730) I wrote up test case 552. The
test is doing a 70K POST with a read callback and an ioctl callback over a
proxy requiring Digest auth. The test case code is more or less identical to
the test recipe code provided by Spacen Jasset (who submitted the bug report).

(http://curl.haxx.se/bug/view.cgi?id=1856628) and provided a fix for the
(small) memory leak in the SSL session ID caching code. It happened when a
previous entry in the cache was re-used.

--manual text.

a file truncation problem on Windows build targets triggered when retrying
a download with curl.

and makes wrong asumptions of build target when it isn't specified. So,
if no build target has been defined we will target WinXP when building
with MSVC 9.0 (VS2008).

defines in the SDK somehow differently so we have to add a define to the
config-win32.h file to make select.h compile nicely.

(http://curl.haxx.se/bug/view.cgi?id=1849764) with an included fix. He
identified a problem for re-used connections that previously had sent
Expect: 100-continue and in some situations the subsequent POST (that didn't
use Expect:) still had the internal flag set for its use. David's fix (that
makes the setting of the flag in every single request unconditionally) is
fine and is now used!

added the --no-keep-alive option that can disable that on demand.

(http://curl.haxx.se/bug/view.cgi?id=1847501) and pointed out a memcpy()
that should be memmove() in the convert_lineends() function.

to do things you don't otherwise do, but here's the summary of today's work...

callback) over a proxy when NTLM is used as auth with the proxy. The bug
also concerned Digest and was limited to using callback only. Spacen worked
with us to provide a useful patch. I added the test case 547 and 548 to
verify two variations of POST over proxy with NTLM.

a problem with SSL session caching that prevent it from working, and the
associated fix!

SSL-based server doesn't present a certificate when the request is told to
ignore certificate verification anyway.

the appending of the "type=" thing on FTP URLs when they are passed to a
HTTP proxy. Some proxies just don't like that appending (which is done
unconditionally in 7.17.1), and some proxies treat binary/ascii transfers
better with the appending done!

which don't have one.

and documentation.

the same state struct as the host auth, so both could never be used at the
same time! I fixed it (without being able to check) to use two separate
structs to allow authentication using Negotiate on host and proxy
simultanouesly.

data sent in a post.

the lib was built staticly.

start so that subsequent tries are simply skipped.

callback was used, as it could wrongly pass on a bad size for the outgoing
HTTP header. The bad size would be a very large value as it was a wrapped
size_t content. This happened when the whole HTTP request failed to get sent
in one single send.  http://curl.haxx.se/mail/lib-2007-11/0165.html

ipv6 server can't run.

huge send buffer sizes

persistent connection. Mentioned by Immanuel Gregoire on the mailing list.

forwarded from the Gentoo bug tracker by Daniel Black and was originally
submitted by Robin Johnson, pointed out that libcurl would do bad memory
references when it failed and bailed out before the handler thing was
setup. My fix is not done like the provided patch does it, but instead I
make sure that there's never any chance for a NULL pointer in that struct
member.

out that SFTP requests didn't use persistent connections. Neither did SCP
ones.  I gave the SSH code a good beating and now both SCP and SFTP should
use persistent connections fine. I also did a bunch for indent changes as
well as a bug fix for the "keyboard interactive" auth.

callbacks needed to pass a buffer to the user.  Instead one per byte it
is now as little as one per segment.

out a problem in curl.h when building C++ apps with MSVC. To fix it, the
inclusion of header files in curl.h is moved outside of the C++ extern "C"
linkage block.
