CHANGES

  OpenSSH 2.9.9, SunSSH 1.0 or later versions. SOCKS5 tests need OpenSSH
  3.7, SunSSH 1.0 or later.

- I fixed two cases of missing return code checks when handling chunked
  decoding where a write error (or abort return from a callback) didn't stop
  libcurl's processing.

- I removed the socklen_t use from the public curl/curl.h header and instead
  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.

- Richard Atterer brought a patch that added support for SOCKS4a proxies,
  which 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.

- Mohun Biswas pointed out that --libcurl generated a source code with an int
  function but without a return statement. While fixing that, I also took care
  about adding some better comments for the generated code.
