Commit 38203f1585 changed engine detection to be version-based,
with a baseline of openssl 1.0.1. This does in fact break builds
with openssl 1.0.0, which has engine support - the configure script
detects that ENGINE_cleanup() is available - but <openssl/engine.h>
doesn't get included to declare it.
According to upstream documentation, engine support was added to
mainstream openssl builds as of version 0.9.7:

This commit drops the version test down to 1.0.0 as version 1.0.0d

OpenSSL has supported --cacert for ages, always accepting LF-only line
endings ("Unix line endings") as well as CR/LF line endings ("Windows
line endings").
When we introduced support for --cacert also with Secure Channel (or in
cURL speak: "WinSSL"), we did not take care to support CR/LF line
endings, too, even if we are much more likely to receive input in that
form when using Windows.
Let's fix that.
Happily, CryptQueryObject(), the function we use to parse the ca-bundle,
accepts CR/LF input already, and the trailing LF before the END
CERTIFICATE marker catches naturally any CR/LF line ending, too. So all
we need to care about is the BEGIN CERTIFICATE marker. We do not
actually need to verify here that the line ending is CR/LF. Just
checking for a CR or an LF is really plenty enough.

- Move verify_certificate functionality in schannel.c into a new
file called schannel_verify.c. Additionally, some structure defintions
from schannel.c have been moved to schannel.h to allow them to be
used in schannel_verify.c.
- Make verify_certificate functionality for Schannel available on
all versions of Windows instead of just Windows CE. verify_certificate
will be invoked on Windows CE or when the user specifies
CURLOPT_CAINFO and CURLOPT_SSL_VERIFYPEER.
- In verify_certificate, create a custom certificate chain engine that
exclusively trusts the certificate store backed by the CURLOPT_CAINFO
file.
- doc updates of --cacert/CAINFO support for schannel
- Use CERT_NAME_SEARCH_ALL_NAMES_FLAG when invoking CertGetNameString
when available. This implements a TODO in schannel.c to improve
handling of multiple SANs in a certificate. In particular, all SANs
will now be searched instead of just the first name.
- Update tool_operate.c to not search for the curl-ca-bundle.crt file
when using Schannel to maintain backward compatibility. Previously,
any curl-ca-bundle.crt file found in that search would have been
ignored by Schannel. But, with CAINFO support, the file found by
that search would have been used as the certificate store and
could cause issues for any users that have curl-ca-bundle.crt in
the search path.
- Update url.c to not set the build time CURL_CA_BUNDLE if the selected
SSL backend is Schannel. We allow setting CA location for schannel
only when explicitly specified by the user via CURLOPT_CAINFO /
--cacert.
- Add new test cases 3000 and 3001. These test cases check that the first
and last SAN, respectively, matches the connection hostname. New test
certificates have been added for these cases. For 3000, the certificate
prefix is Server-localhost-firstSAN and for 3001, the certificate
prefix is Server-localhost-secondSAN.

curl 7.57.0 and up interpret this according to Appendix E.3.2 of RFC
8089 but then returns an error saying this is unimplemented. This is
actually a regression in behavior on both Windows and Unix.
Before curl 7.57.0 this URL was treated as a path of "//foo/bar" and
then passed to the relevant OS API. This means that the behavior of this
case is actually OS dependent.
The Unix path resolution rules say that the OS must handle swallowing
the extra "/" and so this path is the same as "/foo/bar"
The Windows path resolution rules say that this is a UNC path and
automatically handles the SMB access for the program. So curl on Windows
was already doing Appendix E.3.2 without any special code in curl.

Unit test 1307 updated for this new situation.
Closes#2273
... since the libc provided one are locale dependent in a way we don't
want. Also, the "native" isalnum() (for example) works differently on
different platforms which caused test 1307 failures on macos only.
Closes#2269
Make curl_getdate() handle dates before 1970 as well (returning negative
values).
Make test 517 test dates for 64 bit time_t.
This fixes bug (3) mentioned in #2238Closes#2250
... unless CURLOPT_UNRESTRICTED_AUTH is set to allow them. This matches how
curl already handles Authorization headers created internally.
Note: this changes behavior slightly, for the sake of reducing mistakes.
Added test 317 and 318 to verify.

In case an identity didn't match[0], the state machine would fail in
state SSH_AUTH_AGENT instead of progressing to the next identity in
ssh-agent. As a result, ssh-agent authentication only worked if the
identity required happened to be the first added to ssh-agent.
This was introduced as part of commit c4eb10e2f0, which
stated that the "else" statement was required to prevent getting stuck
in state SSH_AUTH_AGENT. Given the state machine's logic and libssh2's
interface I couldn't see how this could happen or reproduce it and I
also couldn't find a more detailed description of the problem which
would explain a test case to reproduce the problem this was supposed to
fix.
[0] libssh2_agent_userauth returning LIBSSH2_ERROR_AUTHENTICATION_FAILED

Follow-up to 84fcaa2e7. libressl does not have the API even if it says it is

1. don't use "ULL" suffix since unsupported in older MSVC
2. use curl_off_t instead of custom long long ifdefs
3. make get_posix_time() not do unaligned data access
Fixes#2211Closes#2240

A mime tree attached to an easy handle using CURLOPT_MIMEPOST is
strongly bound to the handle: there is a pointer to the easy handle in
each item of the mime tree and following the parent pointer list
of mime items ends in a dummy part stored within the handle.
Because of this binding, a mime tree cannot be shared between different
easy handles, thus it needs to be cloned upon easy handle duplication.
There is no way for the caller to get the duplicated mime tree
handle: it is then set to be automatically destroyed upon freeing the
new easy handle.
New test 654 checks proper mime structure duplication/release.
Add a warning note in curl_mime_data_cb() documentation about sharing
user data between duplicated handles.
Closes#2235
