digest: unquote realm and nonce before processing
RFC 7616 (and 2617) requires values to be "unquoted" before used for
digest calculations. The only place where unquoting can be done
correctly is header parsing function (realm="DOMAIN\\host" and
realm=DOMAN\\host are different realms).

This commit adds unquoting (de-escaping) of all values during header
parsing and quoting of the values during header forming. This approach
should be most straightforward and easy to read/maintain as all values
are processed in the same way as required by RFC.

Closes #8912

5a41abef6d ntlm: copy NTLM_HOSTNAME to host buffer
Commit 709ae2454f added a fake hostname to avoid leaking the local
hostname, but omitted copying it to the host buffer.  Fix by copying
and adjust the test fallout.

ntlm: provide a fixed fake host name
The NTLM protocol includes providing the local host name, but apparently
other implementations already provide a fixed fake name instead to avoid
leaking the real local name.

The exact name used is 'WORKSTATION', because Firefox uses that.

The change is written to allow someone to "back-pedal" fairly easy in
case of need.

auth: do not append zero-terminator to authorisation id in kerberos
RFC4752 Section 3.1 states "The authorization identity is not terminated
with a zero-valued (%x00) octet". Although a comment in code said it may
be needed anyway, nothing confirms it. In addition, servers may consider
it as part of the identity, causing a failure.

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()

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.
