Builds with axTLS 2.1.2. This then also breaks compatibility with axTLS
< 2.1.0 (the older API)
... and fix the session_id mixup brought in 04b4ee549Fixes#1220
If the NSS code was in the middle of a non-blocking handshake and it
was asked to finish the handshake in blocking mode, it unexpectedly
continued in the non-blocking mode, which caused a FTPS connection
over CONNECT to fail with "(81) Socket not ready for send/recv".

The information extracted from the server certificates in step 3 is only
used when in verbose mode, and there is no error handling or validation
performed as that has already been done. Only run the certificate
information extraction when in verbose mode and libcurl was built with
verbose strings.

- Remove the SNI disabled when host verification disabled message
since that is incorrect.
- Show a message for legacy versions of Windows <= XP that connections
may fail since those versions of WinSSL lack SNI, algorithms, etc.

SSL_CTX_add_extra_chain_cert takes ownership of the given certificate
while, despite the similar name, SSL_CTX_add_client_CA does not. Thus
it's best to call SSL_CTX_add_client_CA before
SSL_CTX_add_extra_chain_cert, while the code still has ownership of the
argument.

Check for presence of gnutls_alpn_* and gnutls_ocsp_* functions during
configure instead of relying on the version number. GnuTLS has options
to turn these features off and we ca just work with with such builds
like we work with older versions.

Closes#1204
Fixed an old leftover use of the USE_SSLEAY define which would make a
socket get removed from the applications sockets to monitor when the
multi_socket API was used, leading to timeouts.
Bug: #1174
Fixes a few issues in manual wildcard cert name validation in
schannel support code for Win32 CE:
- when comparing the wildcard name to the hostname, the wildcard
character was removed from the cert name and the hostname
was checked to see if it ended with the modified cert name.
This allowed cert names like *.com to match the connection
hostname. This violates recommendations from RFC 6125.
- when the wildcard name in the certificate is longer than the
connection hostname, a buffer overread of the connection
hostname buffer would occur during the comparison of the
certificate name and the connection hostname.
ERR_PACK is an internal detail of OpenSSL. Also, when using it, a
function name must be specified which is overly specific: the test will
break whenever OpenSSL internally change things so that a different
function creates the error.
Closes#1157

* HTTPS proxies:
An HTTPS proxy receives all transactions over an SSL/TLS connection.
Once a secure connection with the proxy is established, the user agent
uses the proxy as usual, including sending CONNECT requests to instruct
the proxy to establish a [usually secure] TCP tunnel with an origin
server. HTTPS proxies protect nearly all aspects of user-proxy
communications as opposed to HTTP proxies that receive all requests
(including CONNECT requests) in vulnerable clear text.
With HTTPS proxies, it is possible to have two concurrent _nested_
SSL/TLS sessions: the "outer" one between the user agent and the proxy
and the "inner" one between the user agent and the origin server
(through the proxy). This change adds supports for such nested sessions
as well.
A secure connection with a proxy requires its own set of the usual SSL
options (their actual descriptions differ and need polishing, see TODO):
--proxy-cacert FILE CA certificate to verify peer against
--proxy-capath DIR CA directory to verify peer against
--proxy-cert CERT[:PASSWD] Client certificate file and password
--proxy-cert-type TYPE Certificate file type (DER/PEM/ENG)
--proxy-ciphers LIST SSL ciphers to use
--proxy-crlfile FILE Get a CRL list in PEM format from the file
--proxy-insecure Allow connections to proxies with bad certs
--proxy-key KEY Private key file name
--proxy-key-type TYPE Private key file type (DER/PEM/ENG)
--proxy-pass PASS Pass phrase for the private key
--proxy-ssl-allow-beast Allow security flaw to improve interop
--proxy-sslv2 Use SSLv2
--proxy-sslv3 Use SSLv3
--proxy-tlsv1 Use TLSv1
--proxy-tlsuser USER TLS username
--proxy-tlspassword STRING TLS password
--proxy-tlsauthtype STRING TLS authentication type (default SRP)
All --proxy-foo options are independent from their --foo counterparts,
except --proxy-crlfile which defaults to --crlfile and --proxy-capath
which defaults to --capath.
Curl now also supports %{proxy_ssl_verify_result} --write-out variable,
similar to the existing %{ssl_verify_result} variable.
Supported backends: OpenSSL, GnuTLS, and NSS.
* A SOCKS proxy + HTTP/HTTPS proxy combination:
If both --socks* and --proxy options are given, Curl first connects to
the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS
proxy.
TODO: Update documentation for the new APIs and --proxy-* options.
Look for "Added in 7.XXX" marks.
Now Curl_rand() is made to fail if it cannot get the necessary random
level.
Changed the proto of Curl_rand() slightly to provide a number of ints at
once.
Moved out from vtls, since it isn't a TLS function and vtls provides
Curl_ssl_random() for this to use.
