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.

The missing file has not been autogenerated because a temporary fix was
employed in acinclude.m4 which blocked update. Removed that fix and a recent
version of missing is copied to build root.

test(1) on HP-UX requires a single equals sign and fails with two.
Let's use one and make every OS happy.

That option is not mentioned in the man page of libtoolize 2.4.4.19-fda4.
Moveover, a comment in line 2623 says "--automake is for 1.5 compatibility".

This option is redundant now.

- update default versions of dependencies (except for rare/old platforms)
- update urls
- sync examples makefiles with main ones
- remove line ending space

* install-sh is always regenerated
* mkinstalldirs was already redudant years ago. Automake uses install for
  that. See: http://lists.gnu.org/archive/html/automake/2007-03/msg00015.html

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)

I've not mentioned the bug fixes that were shipped in 7.42.1 from the
7_42 branch.

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

It would otherwise cause problems when running tests after 1801 etc.

... as it was previouly undocumented what the pointer was.

... and have git ignore that. Allows for a dev to add tests to ignore in
local tests and yet don't obstruct a normal git work flow.

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

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

Add new option --data-raw which is almost the same as --data but does
not have a special interpretation of the @ character.

Prior to this change there was no (easy) way to pass the @ character as
the first character in POST data without it being interpreted as a
special character.
