didn't continue to try the other auth methods. Now it will instead try to
get the files id_dsa.pub and id_dsa from the current directory if none of
the two conditions were met.

and allow reuse by multiple protocols. Several unused error codes were
removed.  In all cases, macros were added to preserve source (and binary)
compatibility with the old names.  These macros are subject to removal at
a future date, but probably not before 2009.  An application can be
tested to see if it is using any obsolete code by compiling it with the
CURL_NO_OLDIES macro defined.

passed to it with curl_easy_setopt()! Previously it has always just refered
to the data, forcing the user to keep the data around until libcurl is done
with it. That is now history and libcurl will instead clone the given
strings and keep private copies.

issue is in libssh2 and not freeing a dynamic error message during cleanup.

* Move scp:// into a state machine so it won't block in multi mode
* When available use the full directory entry from the sftp:// server

patch, then the error message return by the server will be used instead
of a more generic error.

This also fixed failure of test 614 on a system that previously failed.

with the latest libssh2, the listing would be truncated at the symlink.
Fix by looping on LIBSSH2_ERROR_EAGAIN, like the rest of the calls.

uses the --ftp-create-dirs flag to control if cURL will try and create
directories that are specified in an upload path, but don't exist.

ie 0.14, that don't know about newer constants used in the state machine.

  libssh2_sftp_shutdown() and libssh2_session_free() can now return
  LIBSSH2_ERROR_EAGAIN.

memory leak, and it is the right thing to do.

* As of (LIBSSH2_APINO >= 200706012030) there are not *nb() functions
* As of (LIBSSH2_APINO >= 200706012030) most libssh2_*() functions
  can return LIBSSH2_ERROR_EAGAIN to indicate that the call would block.

To make the code work as previously, blocking, all the code has been
updated so that when (LIBSSH2_APINO >= 200706012030) it loops simulating
blocking.  This allows the existing code to function and not hold up
the upcoming release.
