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.

complicated work-around for 64bit HPUX compiles. We do the fix using inline
static functions to make them follow the header file properly and thus get
used fine in the test suite too etc.

  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.

a connection through a socks proxy doesn't work

to find that it crashed miserably, and this was due to some select()isms left
in the code. This was due to API restrictions in c-ares 1.3.x, but with the
upcoming c-ares 1.4.0 this is no longer the case so now libcurl runs much
better with c-ares and the multi interface with > 1024 file descriptors in
use.

hundreds of parallel transfers...

I also switched from calloc() to malloc() as a minor performance boost since
the rest of the code fills in the structs fine anyway - and they must for the
case when we use the stack-based auto variable array instead of the allocated
one.

I made the loop filling in poll_fds[] break when poll_nfds is reached as a
minor speed improvement.

sftp didn't truncate it first, which would corrupt the file if the new
file was shorter than the old.
