Changed the failure code when TLS v1.1 and v1.2 is requested but not
supported by older OpenSSL versions, following review from libcurl
peers, and reduced the number of required preprocessor if statements.
...with the use of CURL_SSLVERSION_TLSv1_1 and CURL_SSLVERSION_TLSv1_2
being conditional on OpenSSL v1.0.1 as the appropriate flags are not
supported under earlier versions.
Commit ad34a2d5c8 relies on definitions that are only present in
OpenSSL v1.0.1 and up. This quick fix allows the builds that use
older versions of OpenSSL to continue building.
According to the documentation for libssh2_userauth_list(), a NULL
return value is not necessarily an error. You must call
libssh2_userauth_authenticated() to determine if the SSH_USERAUTH_NONE
request was successful.
This fixes a segv when using sftp on a server that allows logins with an
empty password. When NULL was interpreted as an error, it would
free the session but not flag an error since the libssh2 errno would be
clear. This resulted in dereferencing a NULL session pointer.

CURL_SSLVERSION_TLSv1_0, CURL_SSLVERSION_TLSv1_1,
CURL_SSLVERSION_TLSv1_2 enum values are added to force exact TLS version
(CURL_SSLVERSION_TLSv1 means TLS 1.x).
axTLS:
axTLS only supports TLS 1.0 and 1.1 but it cannot be set that only one
of these should be used, so we don't allow the new enum values.
darwinssl:
Added support for the new enum values.
SChannel:
Added support for the new enum values.
CyaSSL:
Added support for the new enum values.
Bug: The original CURL_SSLVERSION_TLSv1 value enables only TLS 1.0 (it
did the same before this commit), because CyaSSL cannot be configured to
use TLS 1.0-1.2.
GSKit:
GSKit doesn't seem to support TLS 1.1 and TLS 1.2, so we do not allow
those values.
Bugfix: There was a typo that caused wrong SSL versions to be passed to
GSKit.
NSS:
TLS minor version cannot be set, so we don't allow the new enum values.
QsoSSL:
TLS minor version cannot be set, so we don't allow the new enum values.
OpenSSL:
Added support for the new enum values.
Bugfix: The original CURL_SSLVERSION_TLSv1 value enabled only TLS 1.0,
now it enables 1.0-1.2.
Command-line tool:
Added command line options for the new values.
The option '--bearer' might be slightly ambiguous in name. It doesn't
create any conflict that I am aware of at the moment, however, OAUTH v2
is not the only authentication mechanism which uses "bearer" tokens.

Setting only CURLOPT_SSL_VERIFYHOST without CURLOPT_SSL_VERIFYPEER set
should still verify that the host name fields in the server certificate
is fine or return failure.

...as it is no longer required following capability and authentication
changes and is now causing problems following commit 49341628b5 as
the test number is obtained from the client address in the EHLO.
...to the client address as this frees the RCPT strings to contain
just an email address and by passing the test number into curl as the
client address remains consistent with POP3 and IMAP tests as they are
specified in the URL.
