Updates the test suite to handle binary-mode header output.

Since protocol headers contain explicit line-endings there should
be no automatic conversion to ASCII text or CRLF line-endings.

This might break third party tools that already depend on this
behaviour. We might need to introduce an option to make this optional.

Changes LF to CRLF and disables automatic output conversion.

Do not try to convert line-endings to CRLF on Windows by setting stdout
to binary mode, just like the curl tool does if --ascii is not specified.

This should prevent corrupted stdout line-ending output like CRCRLF.

In order to make the previously naive text-aware tests work with
binary mode on Windows, text-mode is disabled for them if it is not
actually part of the test case and line-endings are corrected.

According to RFC 2616 and RFC 2326 individual protocol elements, like
headers and except the actual content, are terminated by using CRLF.

Therefore the test data files for these protocols need to contain
mixed line-endings if the actual protocol elements use CRLF while
the file uses LF.

The word CURLOPT_PROXYPORT became detached from its sentence when the
note about the default was added.

gcc 4.7.2 with -O2 will optimize Curl_connect by inlining some
functions two levels deep, which makes the valgrind suppression
fail to match. The underlying reason for these idna suppressions is
a gcc strlen optimization when compiling libidn; compiling it with
-fno-builtin-strlen makes this suppression unnecessary.

Bug: https://github.com/bagder/curl/pull/90

For a function that returns a decoded version of a string, it seems
really strange to allow a NULL pointer to get passed in which then
prevents the decoded data from being returned!

This functionality was not documented anywhere either.

If anyone would use it that way, that memory would've been leaked.

Make sure that the special NTLM magic we do is for HTTP+NTLM only since
that's where the authenticated connection is a weird non-standard
paradigm.

Replaced the #define CURL_TIMEOUT_EXPECT_100 in transfer.c with the
CURLOPT_EXPECT_100_TIMEOUT_MS option to make the timeout configurable.

The source files from lib/vtls where generated in lib instead of lib/vtls.

The code didn't properly check the return codes to detect overflows so
it could trigger incorrectly. Like on mingw32.

Disable ALPN or NPN if requested by the user.

Disable ALPN if requested by the user.

See http://curl.haxx.se/mail/lib-2014-02/0004.html for a
discussion on the problem.

Commmit c5f8e2f5 removed the easy handle clean-up from tool_operate,
letting the code that was already present in free_config_fields()
perform the task. Unfortunately, this wasn't the correct place to do
this as it broke protocols, that would perform a logout, as the main
clean-up in tool_main had already been called.

It seems the fips config option causes an error if FIPS mode was
not enabled at stunnel compile-time.  FIPS support was disabled
by default in stunnel 5.00, so this is probably really only needed
on versions between 4.32 and 5.00.

when using --http2 one can now selectively disable NPN or ALPN with
--no-alpn and --no-npn. for now honored with NSS only.

TODO: honor this option with GnuTLS and OpenSSL

SSL_ENABLE_ALPN can be used for preprocessor ALPN feature detection,
but not SSL_NEXT_PROTO_SELECTED, since it is an enum value and not a
preprocessor macro.
