The URL is not a property of the connection so it should not be freed in
the connection disconnect but in the Curl_close() that frees the easy
handle.

Should've been amended in the previous commit but wasn't due to a
mistake.

... and some other cleanups

...From "mutual" to "mutual_auth" which better describes what it is.

Corrected a number of the error codes that can be returned from the
Curl_sasl_create_gssapi_security_message() function when things go
wrong.

It makes more sense to return CURLE_BAD_CONTENT_ENCODING when the
inbound security challenge can't be decoded correctly or doesn't
contain the KERB_WRAP_NO_ENCRYPT flag and CURLE_OUT_OF_MEMORY when
EncryptMessage() fails. Unfortunately the previous error code of
CURLE_RECV_ERROR was a copy and paste mistakes on my part and should
have been correct in commit 4b491c67 :(

Updated "FTP 4.6 GSSAPI via Windows SSPI" and "SASL 14.1 Other
authentication mechanisms" following recent additions.

Added SASL 14.2 GSSAPI via GSS-API libraries.

This repeats what has already been documented in both the curl manpage
and CURLOPT_USERPWD documentation but is provided here for completeness
as someone may not especially read the latter when using libcurl.

Added information about Kerberos V5 requiring the domain part in the
user name.

Mentioned that the user name can be specified in UPN format, and not
just in Down-Level Logon Name format, following the information
added in commit 7679cb3f reworking the exisitng information in the
process.

... to handle "*/[total]". Also, removed the strange hack that made
CURLOPT_FAILONERROR on a 416 response after a *RESUME_FROM return
CURLE_OK.

warning: unused variable 'resp'

warning: no previous prototype for 'Curl_sasl_gssapi_cleanup'

* curl_sasl_sspi.c: Fixed compilation warning from commit 4b491c67

warning: declaration of 'result' shadows a previous local

warning: 'struct kerberos5data' declared inside parameter list

Due to missing forward declaration.

warning: extra tokens at end of #endif directive

Added a kerberos5data structure which is similar in nature to the
ntlmdata and negotiatedata structures.

In preparation for the upcoming SSPI implementation of GSSAPI
authentication, moved the definition of KERB_WRAP_NO_ENCRYPT from
socks_sspi.c to curl_sspi.h allowing it to be shared amongst other
SSPI based code.

... as mxr.mozilla.org is due to be retired.

The new host doesn't support If-Modified-Since nor ETags, meaning that
the script will now defer to download and do a post-transfer checksum
check to see if a new output is to be generated. The new output format
will hold the SHA1 checksum of the source file for that purpose.

We call this version 1.22

Bug: http://curl.haxx.se/bug/view.cgi?id=1409

Fixed libcurl to correctly output the newer versions of OpenSSL 0.9.8,
starting from openssl-0.9.8za.

Bringing back the old functionality that was mistakenly removed when the
connection cache was remade. When creating a new connection, all the
existing ones are checked and those that are known to be dead get
disconnected for real and removed from the connection cache. It helps
the cache from holding on to very many stale connections and aids in
keeping down the number of system sockets in wait states.

Reported-by: David Shaw

Curl_poll and Curl_wait_ms require the fix applied to Curl_socket_check
in commits b61e8b81 and c771968a:

When poll or select are interrupted and coincides with the timeout
elapsing, the functions return -1 indicating an error instead of 0 for
the timeout.

Added copyright due to warning from checksrc.pl.

Given the SSPI package info query indicates a token size of 4096 bytes,
updated to use a dynamic buffer for the response message generation
rather than a fixed buffer of 1024 bytes.
