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 7679cb3fa8 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.

Bug: http://curl.haxx.se/mail/lib-2014-06/0221.html
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

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.

Curl_poll and Curl_wait_ms require the fix applied to Curl_socket_check
in commits b61e8b8 and c771968:
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.
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.
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.
Given the SSPI package info query indicates a token size of 2888 bytes,
and as with the Winbind code and commit 9008f3d56, 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.
