Don't use a hard coded size of 4 for the security layer and buffer size
in Curl_sasl_create_gssapi_security_message(), instead, use sizeof() as
we have done in the sasl_gssapi module.
Reduced the amount of free's required for the decoded challenge message
in Curl_sasl_create_gssapi_security_message() as a result of coding it
differently in the sasl_gssapi module.
Sending NTLM/Negotiate header again after successful authentication
breaks the connection with certain Proxies and request types (POST to MS
Forefront).
The ability to do HTTP requests over a UNIX domain socket has been
requested before, in Apr 2008 [0][1] and Sep 2010 [2]. While a
discussion happened, no patch seems to get through. I decided to give it
a go since I need to test a nginx HTTP server which listens on a UNIX
domain socket.
One patch [3] seems to make it possible to use the
CURLOPT_OPENSOCKETFUNCTION function to gain a UNIX domain socket.
Another person wrote a Go program which can do HTTP over a UNIX socket
for Docker[4] which uses a special URL scheme (though the name contains
cURL, it has no relation to the cURL library).
This patch considers support for UNIX domain sockets at the same level
as HTTP proxies / IPv6, it acts as an intermediate socket provider and
not as a separate protocol. Since this feature affects network
operations, a new feature flag was added ("unix-sockets") with a
corresponding CURL_VERSION_UNIX_SOCKETS macro.
A new CURLOPT_UNIX_SOCKET_PATH option is added and documented. This
option enables UNIX domain sockets support for all requests on the
handle (replacing IP sockets and skipping proxies).
A new configure option (--enable-unix-sockets) and CMake option
(ENABLE_UNIX_SOCKETS) can disable this optional feature. Note that I
deliberately did not mark this feature as advanced, this is a
feature/component that should easily be available.

On some platforms curl would crash if no credentials were used. As such
added detection of such a use case to prevent this from happening.

This patch prepares for adding UNIX domain sockets support.
TCP_NODELAY and TCP_KEEPALIVE are specific to TCP/IP sockets, so do not
apply these to other socket types. bindlocal only works for IP sockets
(independent of TCP/UDP), so filter that out too for other types.

If the scratch buffer already existed when the CRLF conversion was
performed then the buffer pointer would be checked twice for NULL. This
second check is only necessary if the call to malloc() was performed by
the first check.
