Modified the Curl_ossl_cert_status_request() function to return FALSE
when built with BoringSSL or when OpenSSL is missing the necessary TLS
extensions.
Commit 7a8b2885e2 made some functions static and removed the public
Curl_ prefix. Unfortunately, it also removed the sasl_ prefix, which
is the naming convention we use in this source file.
curl_sasl.c:1221: error C2065: 'mechtable' : undeclared identifier
This error could also happen for non-SSPI builds when cryptography is
disabled (CURL_DISABLE_CRYPTO_AUTH is defined).
There is an issue with conflicting "struct timeval" definitions with
certain AmigaOS releases and C libraries, depending on what gets
included when. It's a minor difference - the OS one is unsigned,
whereas the common structure has signed elements. If the OS one ends up
getting defined, this causes a timing calculation error in curl.
It's easy enough to resolve this at the curl end, by casting the
potentially errorneous calculation to a signed long.
... of the other cert verification checks so that you can set verifyhost
and verifypeer to FALSE and still check the public key.

Use a dynamicly allocated buffer for the temporary SPN variable similar
to how the SASL GSS-API code does, rather than using a fixed buffer of
2048 characters.
Carrying on from commit 037cd0d991, removed the following unimplemented
instances of curlssl_close_all():
Curl_axtls_close_all()
Curl_darwinssl_close_all()
Curl_cyassl_close_all()
Curl_gskit_close_all()
Curl_gtls_close_all()
Curl_nss_close_all()
Curl_polarssl_close_all()
Fixed the following warning and error from commit 3af90a6e19 when SSL

Use the SECURITY_STATUS typedef rather than a unsigned long for the
QuerySecurityPackageInfo() return and rename the variable as per other
areas of SSPI code.
Also known as "status_request" or OCSP stapling, defined in RFC6066 section 8.
This requires GnuTLS 3.1.3 or higher to build, however it's recommended to use
at least GnuTLS 3.3.11 since previous versions had a bug that caused the OCSP
response verfication to fail even on valid responses.
This option can be used to enable/disable certificate status verification using
the "Certificate Status Request" TLS extension defined in RFC6066 section 8.
This also adds the CURLE_SSL_INVALIDCERTSTATUS error, to be used when the
certificate status verification fails, and the Curl_ssl_cert_status_request()
function, used to check whether the SSL backend supports the status_request
extension.
If the session is still used by active SSL/TLS connections, it
cannot be closed yet. Thus we mark the session as not being cached
any longer so that the reference counting mechanism in
Curl_schannel_shutdown is used to close and free the session.

As we get the length for the DN and attribute variables, and we know
the length for the line terminator, pass the length values rather than
zero as this will save Curl_client_write() from having to perform an
additional strlen() call.

Rather than duplicate the code in setup_des_key() for OpenSSL and in

Prefer void for unused parameters, rather than assigning an argument to
itself as a) unintelligent compilers won't optimize it out, b) it can't
be used for const parameters, c) it will cause compilation warnings for
clang with -Wself-assign and d) is inconsistent with other areas of the
curl source code.
Moved our Initialize Security Context return attribute definitions to
the SSPI module, as a) these can be used by other SSPI based providers
and b) the ISC required attributes are defined there.
curl_schannel.h:123: warning: right-hand operand of comma expression
has no effect
Some instances of the curlssl_close_all() function were declared with a
void return type whilst others as int. The schannel version returned
CURLE_NOT_BUILT_IN and others simply returned zero, but in all cases the
return code was ignored by the calling function Curl_ssl_close_all().
For the time being and to keep the internal API consistent, changed all
declarations to use a void return type.
To reduce code we might want to consider removing the unimplemented
versions and use a void #define like schannel does.
For consistency, as we seem to have a bit of a mixed bag, changed all
instances of ipv4 and ipv6 in comments and documentations to use the
correct case.
Otherwise Curl_ssl_init_certinfo() can fail and set the num_of_certs
member variable to the requested count, which could then be used
incorrectly as libcurl closes down.
The return type for this function was 0 on success and 1 on error. This
was then examined by the calling functions and, in most cases, used to
return CURLE_OUT_OF_MEMORY.
Instead use CURLcode for the return type and return the out of memory
error directly, propagating it up the call stack.
The return type of this function is a boolean value, and even uses a
bool internally, so use bool in the function declaration as well as
the variables that store the return value, to avoid any confusion.

Removed 'next' variable in Curl_convert_form(). Rather than setting it

just use 'form = form->next' instead.
There was a confusion between these: this commit tries to disambiguate them.
- Scope can be computed from the address itself.
- Scope id is scope dependent: it is currently defined as 1-based local
interface index for link-local scoped addresses, and as a site index(?) for
(obsolete) site-local addresses. Linux only supports it for link-local
addresses.
The URL parser properly parses a scope id as an interface index, but stores it
in a field named "scope": confusion. The field has been renamed into "scope_id".
Curl_if2ip() used the scope id as it was a scope. This caused failures
to bind to an interface.
Scope is now computed from the addresses and Curl_if2ip() matches them.
If redundantly specified in the URL, scope id is check for mismatch with
the interface index.
This commit should fix SF bug #1451.

There is no need to set the 'state' and 'result' member variables to
SMB_REQUESTING (0) and CURLE_OK (0) after the allocation via calloc()
as calloc() initialises the contents to zero.
I don't think both of my fix ups from yesterday were needed to fix the
compilation warning, so remove the one that I think is unnecessary and
let the next Android autobuild prove/disprove it.

This fixes compilation issues with compilers that don't support 64-bit
integers through long long or __int64 which was introduced in commit
07b66cbfa4.
Previously USE_NTLM2SESSION would only be defined automatically when
USE_NTRESPONSES wasn't already defined. Separated the two definitions
so that the user can manually set USE_NTRESPONSES themselves but
USE_NTLM2SESSION is defined automatically if they don't define it.
As the OpenSSL and NSS Crypto engines are prefered by the core NTLM
routines, to the Windows Crypt API, don't define USE_WIN32_CRYPT
automatically when either OpenSSL or NSS are in use - doing so would
disable NTLM2Session responses in NTLM type-3 messages.
If the scratch buffer was allocated in a previous call to
Curl_smtp_escape_eob(), a new buffer not allocated in the subsequent
call and no action taken by that call, then an attempt would be made to
try and free the buffer which, by now, would be part of the data->state
structure.
This bug was introduced in commit 4bd860a001.
Fixed a problem with the CRLF. detection when multiple buffers were
used to upload an email to libcurl and the line ending character(s)
appeared at the end of each buffer. This meant any lines which started
with . would not be escaped into .. and could be interpreted as the end
of transmission string instead.
This only affected libcurl based applications that used a read function
and wasn't reproducible with the curl command-line tool.

parsedate.c:548: warning: 'parsed' may be used uninitialized in this

As curl_getdate() returns -1 when parsedate() fails we can initialise
parsed to -1.
This fixes the test 506 torture test. The internal cookie API really
ought to be improved to separate cookie parsing errors (which may be
ignored) with OOM errors (which should be fatal).
As Windows based autoconf builds don't yet define USE_WIN32_CRYPTO
either explicitly through --enable-win32-cypto or automatically on
_WIN32 based platforms, subsequent builds broke with the following
error message:
"Can't compile NTLM support without a crypto library."
Fixed an issue with the message size calculation where the raw bytes
from the buffer were interpreted as signed values rather than unsigned
values.
