Prior to this change tests that required NTLM feature did not require
SSL feature.

There are pending changes to cmake builds that will allow enabling NTLM
in non-SSL builds in Windows. In that case the NTLM auth strings created
are different from what is expected by the NTLM tests and they fail:

"The issue with NTLM is that previous non-SSL builds would not enable
NTLM and so the NTLM tests would be skipped."

These tests give differences for me on linux when using a hostip
pointing to the external ip address for the local machine.

Closes #4070

NTLM2 did not work i.e. no NTLMv2 response was created. Changing the
check seems to work.

Fixes https://github.com/curl/curl/issues/3286
Closes https://github.com/curl/curl/pull/3287
Closes https://github.com/curl/curl/pull/3415

Both these tests run the same underlying test code: libntlmconnect.c -
this test code made some assumptions about socket ordering when it used
curl_easy_fdset() and when we changed timing or got accidental changes
in libcurl the tests would fail.

The tests verify that the different transfers keep using the same
connections, which I now instead made sure by adding the number of bytes
each transfer gets and then verifies that they always get the same
amount as when these tests worked.

Closes #1576

Required for the tests to work after a5d994941c2b.

According to RFC 2616 and RFC 2326 individual protocol elements, like
headers and except the actual content, are terminated by using CRLF.

Therefore the test data files for these protocols need to contain
mixed line-endings if the actual protocol elements use CRLF while
the file uses LF.
