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.

...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 :(

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

* 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.

Bug: http://curl.haxx.se/mail/lib-2014-06/0189.html

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.

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.

Due to the reduction of code in commit 3b924b29 of get_gss_name() the
function isn't necessary anymore.

Updated to use a dynamic buffer for the SPN generation via the recently
introduced Curl_sasl_build_spn() function rather than a fixed buffer of
1024 characters, which should have been more than enough, but by using
the new function removes the need for another variable sname to do the
wide character conversion in Unicode builds.

Updated Curl_sasl_create_digest_md5_message() to use a dynamic buffer
for the SPN generation via the recently introduced Curl_sasl_build_spn()
function rather than a fixed buffer of 128 characters.

Curl_sasl_create_digest_md5_message() would simply cast the SPN variable
to a TCHAR when calling InitializeSecurityContext(). This meant that,
under Unicode builds, it would not be valid wide character string.

Updated to use the recently introduced Curl_sasl_build_spn() function
which performs the correct conversion for us.

Various parts of the libcurl source code build a SPN for inclusion in
authentication data. This information is either used by our own native
generation routines or passed to authentication functions in third-party
libraries such as SSPI. However, some of these instances use fixed
buffers rather than dynamically allocated ones and not all of those that
should, convert to wide character strings in Unicode builds.

Implemented a common function that generates a SPN and performs the
wide character conversion where necessary.

Curl_sasl_create_digest_md5_message() wouldn't free the Package Info
structure after QuerySecurityPackageInfo() had allocated it.

Following the recent changes and in attempt to align the SSPI based
authentication code performed the following:

* Use NULL and SECBUFFVERSION rather than hard coded constants.
* Avoid comparison of zero in if statements.
* Standardised the buf and desc setup code.

vtls.c:688:43: warning: unused parameter 'data'

Given the SSPI package info query indicates a token size of 2888 bytes,
and as with the Winbind code and commit 9008f3d5, use a dynamic buffer
for the Type-1 and Type-3 message generation rather than a fixed buffer
of 1024 bytes.

Just as with the SSPI implementations of Digest and Negotiate added a
package info query so that libcurl can a) return a more appropriate
error code when the NTLM package is not supported and b) it can be of
use later to allocate a dynamic buffer for the Type-1 and Type-3
output tokens rather than use a fixed buffer of 1024 bytes.
