Ensure that there isn't a mismatch between setlocal and endlocal calls,
which could have happened due to setlocal being called after certain
error conditions were checked for.
Added the wolfSSL build script, based on build-openssl.bat, as well as
the property sheet and header file required for the upcoming additions
to the Visual Studio project files.
Currently when the server responds with 401 on NTLM authenticated
connection (re-used) we consider it to have failed. However this is
legitimate and may happen when for example IIS is set configured to
'authPersistSingleRequest' or when the request goes thru a proxy (with
'via' header).
Implemented by imploying an additional state once a connection is
re-used to indicate that if we receive 401 we need to restart
authentication.
Closes#363
The SSH state machine didn't clear the 'rc' variable appropriately in a
two places which prevented it from looping the way it should. And it
lacked an 'else' statement that made it possible to erroneously get
stuck in the SSH_AUTH_AGENT state.

Otherwise it would never be called for an HTTP/2 connection, which has
its own disconnect handler.
I spotted this while debugging <https://bugzilla.redhat.com/1248389>
where the http_disconnect() handler was called on an FTP session handle
causing 'dnf' to crash. conn->data->req.protop of type (struct FTP *)
was reinterpreted as type (struct HTTP *) which resulted in SIGSEGV in
Curl_add_buffer_free() after printing the "Connection cache is full,
closing the oldest one." message.
A previously working version of libcurl started to crash after it was
recompiled with the HTTP/2 support despite the HTTP/2 protocol was not
actually used. This commit makes it work again although I suspect the
root cause (reinterpreting session handle data of incompatible protocol)
still has to be fixed. Otherwise the same will happen when mixing FTP
and HTTP/2 connections and exceeding the connection cache limit.
