infof: remove newline from format strings, always append it
- the data needs to be "line-based" anyway since it's also passed to the
  debug callback/application

- it makes infof() work like failf() and consistency is good

- there's an assert that triggers on newlines in the format string

- Also removes a few instances of "..."

- Removes the code that would append "..." to the end of the data *iff*
  it was truncated in infof()

1d5d0ae9e5 lib: fix some misuse of curlx_convert_UTF8_to_tchar
curlx_convert_UTF8_to_tchar must be freed by curlx_unicodefree, but
prior to this change some uses mistakenly called free.

I've reviewed all other uses of curlx_convert_UTF8_to_tchar and
curlx_convert_tchar_to_UTF8.

ntlm: fix negotiated flags usage
According to Microsoft document MS-NLMP, current flags usage is not
accurate: flag NTLMFLAG_NEGOTIATE_NTLM2_KEY controls the use of
extended security in an NTLM authentication message and NTLM version 2
cannot be negotiated within the protocol.

The solution implemented here is: if the extended security flag is set,
prefer using NTLM version 2 (as a server featuring extended security
should also support version 2). If version 2 has been disabled at
compile time, use extended security.

Tests involving NTLM are adjusted to this new behavior.

c54565915f digest_sspi: Show InitializeSecurityContext errors in verbose mode
The error is shown with infof rather than failf so that the user will
see the extended error message information only in verbose mode, and
will still see the standard CURLE_AUTH_ERROR message. For example:

---

* schannel: InitializeSecurityContext failed: SEC_E_QOP_NOT_SUPPORTED
(0x8009030A) - The per-message Quality of Protection is not supported by
the security package
* multi_done
* Connection #1 to host 127.0.0.1 left intact
curl: (94) An authentication function returned an error

vauth/cleartext: fix theoretical integer overflow
Fix theoretical integer overflow in Curl_auth_create_plain_message.

The security impact of the overflow was discussed on hackerone. We

over 4GB of available memory space for the process.

* Curl_output_negotiate: ensure auth done is always set
* Curl_output_negotiate: Set auth done also if result code is
  GSS_S_CONTINUE_NEEDED/SEC_I_CONTINUE_NEEDED as this result code may
  also indicate the last challenge request (only works with disabled

strerror: make the strerror function use local buffers
Instead of using a fixed 256 byte buffer in the connectdata struct.

In my build, this reduces the size of the connectdata struct by 11.8%,
from 2160 to 1904 bytes with no functionality or performance loss.

This also fixes a bug in schannel's Curl_verify_certificate where it
called Curl_sspi_strerror when it should have called Curl_strerror for
string from GetLastError. the only effect would have been no text or the
wrong text being shown for the error.
