... by using plain structs instead of pointers for the connection cache,
we can avoid several dynamic allocations that weren't necessary.

This ensures an alternate address is not used.
Does not apply to proxy tunnel.

Use text mode when cygwin to eliminate trailing carriage returns.

Also print the revocation reason if appropriate.

The symbol is fairly new.

The OpenSSL trace callback is wonderfully undocumented but given a
journey in the source code, it seems the cases were ssl_ver is zero
doesn't follow the same pattern and thus turned out confusing and
misleading. For now, we skip doing any CURLINFO_TEXT logging on those
but keep sending them as CURLINFO_SSL_DATA_OUT/IN.

Also, I added direction to the text info and I edited some functions
slightly.

Commit 145c263a changed the behavior when Curl_read_plain returns
CURLE_AGAIN. We now handle CURLE_AGAIN and SEC_I_CONTEXT_EXPIRED
correctly.

This fixes using a multi-target mingw distro to build curl .dll for the
non-default target.
(mirroring the same patch present in src/makefile.m32)

Make the HTTP headers separated by default for improved security and
reduced risk for information leakage.

* Add new options, CURLOPT_PROXY_SERVICE_NAME and CURLOPT_SERVICE_NAME.
* Add new curl options, --proxy-service-name and --service-name.

So that it fits HTTP/2 as well

To have engine modules work, we must tell openssl to load builtin
modules first.

Without this, SSPI based digest auth was broken.

Bug: https://github.com/bagder/curl/pull/141.patch

The 'default' token has no argument and means to match _any_ domain.
It must be placed last if there are 'machine <name>' tokens in the same file.

Also add public key extraction example to CURLOPT_PINNEDPUBLICKEY doc.

PROTOPT_CREDSPERREQUEST still needs to be checked even when NTLM is not
enabled.

Bug: https://bugzilla.redhat.com/1195771

When doing HTTP requests Negotiate authenticated, the entire connnection
may become authenticated and not just the specific HTTP request which is
otherwise how HTTP works, as Negotiate can basically use NTLM under the
hood. curl was not adhering to this fact but would assume that such
requests would also be authenticated per request.

CVE-2015-3148

Bug: http://curl.haxx.se/docs/adv_20150422B.html
Reported-by: Isaac Boukris

If a URL is given with a zero-length host name, like in "http://:80" or
just ":80", `fix_hostname()` will index the host name pointer with a -1
offset (as it blindly assumes a non-zero length) and both read and
assign that address.

CVE-2015-3144

Bug: http://curl.haxx.se/docs/adv_20150422D.html
Reported-by: Hanno Böck

The internal libcurl function called sanitize_cookie_path() that cleans
up the path element as given to it from a remote site or when read from
a file, did not properly validate the input. If given a path that
consisted of a single double-quote, libcurl would index a newly
allocated memory area with index -1 and assign a zero to it, thus
destroying heap memory it wasn't supposed to.
