Handles created with curl_easy_duphandle do not use the SSL engine set
up in the original handle. This fixes the issue by storing the engine
name in the internal url state and setting the engine from its name
inside curl_easy_duphandle.

This change allows to use the CMake config files generated by Curl's
CMake scripts for static builds of the library.
The symbol CURL_STATIC lib must be defined to compile downstream,
thus the config package is the perfect place to do so.

The verbose message "Authentication using SSH public key file" was
printed each time the ssh_userauth_publickey_auto() was called, which
meant each time a packet was transferred over network because the API
operates in non-blocking mode.
This patch makes sure that the verbose message is printed just once
(when the authentication state is entered by the SSH state machine).
Deal with tiny "HTTP/0.9" (header-less) responses by checking the
status-line early, even before a full "HTTP/" is received to allow
detecting 0.9 properly.
Test 1266 and 1267 added to verify.

This allows the use of PKCS#11 URI for certificates and keys without
setting the corresponding type as "ENG" and the engine as "pkcs11"
explicitly. If a PKCS#11 URI is provided for certificate, key,
proxy_certificate or proxy_key, the corresponding type is set as "ENG"
if not provided and the engine is set to "pkcs11" if not provided.

So far, the code tries to pick an authentication method only if
user/password credentials are available, which is not the case for
Bearer authentictation...
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
Closes#2754
The Bearer authentication was added to cURL 7.61.0, but there is a
problem: if CURLAUTH_ANY is selected, and the server supports multiple
authentication methods including the Bearer method, we strongly prefer
that latter method (only CURLAUTH_NEGOTIATE beats it), and if the Bearer
authentication fails, we will never even try to attempt any other
method.
This is particularly unfortunate when we already know that we do not
have any Bearer token to work with.
Such a scenario happens e.g. when using Git to push to Visual Studio
Team Services (which supports Basic and Bearer authentication among
other methods) and specifying the Personal Access Token directly in the
URL (this aproach is frequently taken by automated builds).
Let's make sure that we have a Bearer token to work with before we
select the Bearer authentication among the available authentication
methods.

It was previously erroneously skipped in some situations.
libtest/libntlmconnect.c wrongly depended on wrong behavior (that it

will always return a -1 timeout when all handles are completed.

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:
https://github.com/openssl/openssl/blob/master/README.ENGINE
This commit drops the version test down to 1.0.0 as version 1.0.0d
is the oldest version I have to test with.

Given the contstraints of SChannel, I'm exposing these as the algorithms
themselves instead; while replicating the ciphersuite as specified by
OpenSSL would have been preferable, I found no way in the SChannel API
to do so.
To use this from the commandline, you need to pass the names of contants
defining the desired algorithms. For example, curl --ciphers
"CALG_SHA1:CALG_RSA_SIGN:CALG_RSA_KEYX:CALG_AES_128:CALG_DH_EPHEM"
