I have to jump through a few hoops now with the NSS library initialization
  since another part of an application may have already initialized NSS by the
  time Curl gets invoked. This patch is more careful to only shutdown the NSS
  library if Curl did the initialization.

  It also adds in a bit of code to set the default ciphers if the app that
  call NSS_Init* did not call NSS_SetDomesticPolicy() or set specific
  ciphers. One might argue that this lets other application developers get
  lazy and/or they aren't using the NSS API correctly, and you'd be right.
  But still, this will avoid terribly difficult-to-trace crashes and is
  generally helpful.

  out that 'reconf' didn't properly point out the m4 subdirectory when running
  aclocal.

added HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID to ares Makefile.netware and sync'd with other Makefile.netware.

changed HAVE_SIN6_SCOPE_ID define to HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID since just found that ares already uses this define.

  (http://curl.haxx.se/bug/view.cgi?id=2413067) that identified a problem that
  would cause libcurl to mark a DNS cache entry "in use" eternally if the
  subsequence TCP connect failed. It would thus never get pruned and refreshed
  as it should've been.

escape these letters what I think is the correct way.

  corrected spellings and more.

 The curl tool parts are postponed to a later time

201 - "bug: header data output to the body callback function after set header"
 Was probably not a bug, I asked about it but I didn't get any response.

202 - "hangs up of application above libcurl" - problems with the multi_socket
 Fixes from Igor have been committed and there's currently no pending ones.

  pipelining, as libcurl could then easily get confused and A) work on the
  handle that was not "first in queue" on a pipeline, or even B) tell the app
  to REMOVE a socket while it was in use by a second handle in a pipeline. Both
  errors caused hanging or stalling applications.

in combination with infof() calls

  was actually ready to get done, as the internal time resolution is higher
  than the returned millisecond timer. Therefore it could cause applications
  running on fast processors to do short bursts of busy-loops.
  curl_multi_timeout() will now only return 0 if the timeout is actually
  alreay triggered.

  now has an improved ability to do right when the multi interface (both
  "regular" and multi_socket) is used for SCP and SFTP transfers. This should
  result in (much) less busy-loop situations and thus less CPU usage with no
  speed loss.

  operation didn't complete properly if the EAGAIN equivalent was returned but
  libcurl would simply continue with a half-completed close operation
  performed. This ruined persistent connection re-use and cause some
  SSH-protocol errors in general. The correction is unfortunately adding a
  blocking function - doing it entirely non-blocking should be considered for
  a better fix.

If USE_WATT32=1 one needs to use stack-based calls (-3s).
So to keep the makefile nice and clean, specify -3s for
Winsock target too (there's hardly any speed-gain using -3r).
