Steve Holme b6821dbb91 sasl: Fixed Kerberos V5 inclusion when CURL_DISABLE_CRYPTO_AUTH is used
Typically the USE_WINDOWS_SSPI definition would not be used when the
CURL_DISABLE_CRYPTO_AUTH define is, however, it is still a valid build
configuration and, as such, the SASL Kerberos V5 (GSSAPI) authentication
data structures and functions would incorrectly be used when they
shouldn't be.

Introduced a new USE_KRB5 definition that takes into account the use of
CURL_DISABLE_CRYPTO_AUTH like USE_SPNEGO and USE_NTLM do.

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.
