Vilmos Nebehaj fd1ce3856a darwinssl: Use CopyCertSubject() to check CA cert.
SecCertificateCopyPublicKey() is not available on iPhone. Use
CopyCertSubject() instead to see if the certificate returned by
SecCertificateCreateWithData() is valid.

Andre Heinecke e608324f9f polarssl: implement CURLOPT_SSLVERSION
Forwards the setting as minimum ssl version (if set) to polarssl.  If
the server does not support the requested version the SSL Handshake will
fail.

Vilmos Nebehaj 0426670f0a Check CA certificate in curl_darwinssl.c.
SecCertificateCreateWithData() returns a non-NULL SecCertificateRef even
if the buffer holds an invalid or corrupt certificate. Call
SecCertificateCopyPublicKey() to make sure cacert is a valid
certificate.

Vilmos Nebehaj 4c134bcfce Fix CA certificate bundle handling in darwinssl.
If the --cacert option is used with a CA certificate bundle that
contains multiple CA certificates, iterate through it, adding each
certificate as a trusted root CA.

Daniel Stenberg 7d2f61f66a openssl: replace call to OPENSSL_config
OPENSSL_config() is "strongly recommended" to use but unfortunately that
function makes an exit() call on wrongly formatted config files which
makes it hard to use in some situations. OPENSSL_config() itself calls
CONF_modules_load_file() and we use that instead and we ignore its
return code!

before the function that takes this priority string, there should be no
issue with backward compatibility.

Tatsuhiro Tsujikawa c7638d93b0 openssl: Fix uninitialized variable use in NPN callback
OpenSSL passes out and outlen variable uninitialized to
select_next_proto_cb callback function.  If the callback function
returns SSL_TLSEXT_ERR_OK, the caller assumes the callback filled
values in out and outlen and processes as such.  Previously, if there
is no overlap in protocol lists, curl code does not fill any values in
these variables and returns SSL_TLSEXT_ERR_OK, which means we are
triggering undefined behavior.  valgrind warns this.

This patch fixes this issue by fallback to HTTP/1.1 if there is no
overlap.

David Ryskalczyk 63fc8ee7be winssl: Enable hostname verification of IP address using SAN or CN
Original commit message was:
 Don't omit CN verification in SChannel when an IP address is used.

Side-effect of this change:
 SChannel and CryptoAPI do not support the iPAddress subjectAltName
 according to RFC 2818. If present, SChannel will first compare the
 IP address to the dNSName subjectAltNames and then fallback to the
 most specific Common Name in the Subject field of the certificate.

 This means that after this change curl will not connect to SSL/TLS
 hosts as long as the IP address is not specified in the SAN or CN
 of the server certificate or the verifyhost option is disabled.

Fabian Frank 4d8db595ca gtls: add ALPN support
Add ALPN support when using GnuTLS >= 3.2.0. This allows
libcurl to negotiate HTTP/2.0 for https connections when
built with GnuTLS.

Fabian Frank 8b6654224b openssl: add ALPN support
Add ALPN support when using OpenSSL. This will offer ALPN and NPN to the
server, who can respond with either one or none of the two. OpenSSL >=
1.0.2 is required, which means as of today obtaining a snapshot from
ftp://ftp.openssl.org/snapshot/.

Marc Hoersken 82f558366f winssl: improved default SSL/TLS protocol selection
For some reason Windows 7 SP1 chooses TLS 1.0 instead of TLS 1.2
if it is not explicitly enabled within grbitEnabledProtocols.

Fabian Frank 22c198fa89 openssl: set up hooks with to perform NPN
NPN is what is available in the wild today to negotiate SPDY or HTTP/2.0
connections. It is expected to be replaced by ALPN in the future. If
HTTP/2.0 is negotiated, this is indicated for the entire connection and
http.c is expected to initialize itself for HTTP/2.0 instead of
HTTP/1.1.

Make GnuTLS old and new consistent, specify the desired protocol, cipher

as reported by howsmyssl.com. Honor not only --sslv3, but also the
--tlsv1[.N] switches.

Daniel Stenberg 3b5c75ef3d OpenSSL: deselect weak ciphers by default
By default even recent versions of OpenSSL support and accept both
"export strength" ciphers, small-bitsize ciphers as well as downright
deprecated ones.

This change sets a default cipher set that avoids the worst ciphers, and
subsequently makes https://www.howsmyssl.com/a/check no longer grade
curl/OpenSSL connects as 'Bad'.

Barry Abrahamson 4bb7400529 OpenSSL: Fix forcing SSLv3 connections
Some feedback provided by byte_bucket on IRC pointed out that commit
db11750cfa wasn’t really correct because it allows for “upgrading” to a
newer protocol when it should be only allowing for SSLv3.

This change fixes that.

When SSLv3 connection is forced, don't allow SSL negotiations for newer
versions.  Feedback provided by byte_bucket in #curl.  This behavior is
also consistent with the other force flags like --tlsv1.1 which doesn't
allow for TLSv1.2 negotiation, etc

Barry Abrahamson db11750cfa OpenSSL: Fix forcing SSLv3 connections
Since ad34a2d5c8 (present in 7.34.0 release) forcing
SSLv3 will always return the error "curl: (35) Unsupported SSL protocol
version" Can be replicated with `curl -I -3 https://www.google.com/`.
This fix simply allows for v3 to be forced.
