John E. Malmberg f9cf3de70b VMS: Updates for 0740-0D1220
lib/setup-vms.h : VAX HP OpenSSL port is ancient, needs help.
                  More defines to set symbols to uppercase.

src/tool_main.c : Fix parameter to vms_special_exit() call.

packages/vms/ :
  backup_gnv_curl_src.com : Fix the error message to have the correct package.

  build_curl-config_script.com : Rewrite to be more accurate.

  build_libcurl_pc.com : Use tool_version.h now.

  build_vms.com : Fix to handle lib/vtls directory.

  curl_gnv_build_steps.txt : Updated build procedure documentation.

  generate_config_vms_h_curl.com :
       * VAX does not support 64 bit ints, so no NTLM support for now.
       * VAX HP SSL port is ancient, needs some help.
       * Disable NGHTTP2 for now, not ported to VMS.
       * Disable UNIX_SOCKETS, not available on VMS yet.
       * HP GSSAPI port does not have gss_nt_service_name.

  gnv_link_curl.com : Update for new curl structure.

  pcsi_product_gnv_curl.com : Set up to optionally do a complete build.

HTTP Pipelining with libcurl
============================

Background

Since pipelining implies that one or more requests are sent to a server before
the previous response(s) have been received, we only support it for multi
interface use.

Considerations

When using the multi interface, you create one easy handle for each transfer.
Bascially any number of handles can be created, added and used with the multi
interface - simultaneously. It is an interface designed to allow many
simultaneous transfers while still using a single thread. Pipelining does not
change any of these details.

API

We've added a new option to curl_multi_setopt() called CURLMOPT_PIPELINING
that enables "attempted pipelining" and then all easy handles used on that
handle will attempt to use an existing pipeline.

Details

- A pipeline is only created if a previous connection exists to the same IP
  address that the new request is being made to use.

- Pipelines are only supported for HTTP(S) as no other currently supported
  protocol has features resemembling this, but we still name this feature
  plain 'pipelining' to possibly one day support it for other protocols as
  well.

- HTTP Pipelining is for GET and HEAD requests only.

- When a pipeline is in use, we must take precautions so that when used easy
  handles (i.e those who still wait for a response) are removed from the multi
  handle, we must deal with the outstanding response nicely.

- Explicitly asking for pipelining handle X and handle Y won't be supported.
  It isn't easy for an app to do this association. The lib should probably
  still resolve the second one properly to make sure that they actually _can_
  be considered for pipelining. Also, asking for explicit pipelining on handle
  X may be tricky when handle X get a closed connection.
