CyaSSL 3.0.0 returns a unique error code if no CA cert is available,
so translate that into CURLE_SSL_CACERT_BADFILE when peer verification

CURUL_VERSION_SPNEGO now.

CONNECT: Revert Curl_proxyCONNECT back to 7.29.0 design
This reverts commit cb3e6dfa3511 and instead fixes the problem
differently.
The reverted commit addressed a test failure in test 1021 by simplifying
and generalizing the code flow in a way that damaged the
performance. Now we modify the flow so that Curl_proxyCONNECT() again
does as much as possible in one go, yet still do test 1021 with and
without valgrind. It failed due to mistakes in the multi state machine.

Don't abort Negotiate auth when the server has a response for us
It's wrong to assume that we can send a single SPNEGO packet which will
complete the authentication. It's a *negotiation* — the clue is in the
name. So make sure we handle responses from the server.
Curl_input_negotiate() will already handle bailing out if it thinks the
state is GSS_S_COMPLETE (or SEC_E_OK on Windows) and the server keeps
talking to us, so we should avoid endless loops that way.

Use SPNEGO for HTTP Negotiate
This is the correct way to do SPNEGO. Just ask for it
Now I correctly see it trying NTLMSSP authentication when a Kerberos ticket
isn't available. Of course, we bail out when the server responds with the
challenge packet, since we don't expect that. But I'll fix that bug next...

Remove all traces of FBOpenSSL SPNEGO support
This is just fundamentally broken. SPNEGO (RFC4178) is a protocol which
allows client and server to negotiate the underlying mechanism which will
actually be used to authenticate. This is *often* Kerberos, and can also
be NTLM and other things. And to complicate matters, there are various
different OIDs which can be used to specify the Kerberos mechanism too.
A SPNEGO exchange will identify *which* GSSAPI mechanism is being used,
and will exchange GSSAPI tokens which are appropriate for that mechanism.
But this SPNEGO implementation just strips the incoming SPNEGO packet
and extracts the token, if any. And completely discards the information
about *which* mechanism is being used. Then we *assume* it was Kerberos,
and feed the token into gss_init_sec_context() with the default
mechanism (GSS_S_NO_OID for the mech_type argument).
Furthermore... broken as this code is, it was never even *used* for input
tokens anyway, because higher layers of curl would just bail out if the
server actually said anything *back* to us in the negotiation. We assume
that we send a single token to the server, and it accepts it. If the server
wants to continue the exchange (as is required for NTLM and for SPNEGO
to do anything useful), then curl was broken anyway.
So the only bit which actually did anything was the bit in
Curl_output_negotiate(), which always generates an *initial* SPNEGO
token saying "Hey, I support only the Kerberos mechanism and this is its
token".
You could have done that by manually just prefixing the Kerberos token
with the appropriate bytes, if you weren't going to do any proper SPNEGO
handling. There's no need for the FBOpenSSL library at all.
The sane way to do SPNEGO is just to *ask* the GSSAPI library to do
SPNEGO. That's what the 'mech_type' argument to gss_init_sec_context()
is for. And then it should all Just Work™.
That 'sane way' will be added in a subsequent patch, as will bug fixes
for our failure to handle any exchange other than a single outbound
token to the server which results in immediate success.
