- Change data and protocol sections to CRLF line endings.

Prior to this change the tests would fail or hang, which is because
certain sections such as protocol require CRLF line endings.

Follow-up to a9499ff1 from today which added the tests.

CVE-2019-5436

When running a multi TLS backend build the version string needs more
buffer space. Make the internal ssl_buffer stack buffer match the one
in Curl_multissl_version() to allow for the longer string. For single
TLS backend builds there is no use in extended to buffer. This is a
fallout from #3863 which fixes up the multi_ssl string generation to
avoid a buffer overflow when the buffer is too small.

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.
