                                  Changelog

- Ben Greear made telnet a lot better/easier to use by an application:

  The main change is to allow input from user-specified methods, when they are

  specified with CURLOPT_READFUNCTION.  All calls to fflush(stdout) in

  telnet.c were removed, which makes using 'curl telnet://foo.com' painful

  since prompts and other data are not always returned to the user promptly.

  Use 'curl --no-buffer telnet://foo.com' instead.  In general, the user

  should have their CURLOPT_WRITEFUNCTION do a fflush for interactive use.

  Also fix assumption that reading from stdin never returns < 0.

  Old code could crash in that case.

  Call progress functions in telnet main loop.

- Make use of the libssh2_init/exit functions that libssh2 added in version

  1.2.5. Using them will improve how libcurl works in threaded situations when

 o added the --proto and -proto-redir options

 o new configure option --enable-threaded-resolver

 o improve TELNET ability with libcurl

This release includes the following bugfixes:
