Add compatibility with OpenSSL 1.1.0

In their continued wisdom OpenSSL developers keep breaking APIs left and right
with very poor documentation and forward/backward source compatibility.

Add support for RFC5801

These are the only GSS-API functions that can return a mechanism name
given an oid. These are now used by mod_auth_gssapi, so let's support
them in gssntlmssp.

Add gss_inquire_attrs_for_mech()

Since commit 030a4a03a ("Report inquire_attrs_For_mech mech failures") in
MIT krb5, NTLMSSP fallback within SPNEGO is no longer working. It seems
that providing a gss_inquire_attrs_for_mech() function is now mandatory.

Although it does seem that perhaps krb5 should be a little more forgiving
and just assume GSS_C_NO_OID_SET, fix it anyway.

Drop support for GSS_C_MA_NOT_DFLT_MECH

When this MEchanism Attribute is exposed as supported it causes GSSAPI
implementations to eclude the mechanism completely as vaiable to acquire
creds from pseudo mechanisms like SPNEGO.
This is not what was intended when we added this flag. The intention was
to not make this mechanism the default when mutliple are available, and
specifically to not make it preferred over krb5.
However given this is not how the fal works, we need to drop it now.

It may be re-introduced at a later time as a runtime settings when we
grow a way to set configuration in a file somewhere so that admin can
control this behavior.

Completely omit CBs AV pairs when no CB provided

Although the MS-NLMP Spec says zero CBs should be equivalent to no CBs,
Windows apparently fails validation when CBs are optional and an all
zero CB is presented.

So avoid sending any CBs if we have none.
Also make sure to deal with missing CBs on the accpetor by ignoreing
missing CBs and setting the new GSS_C_CHANNEL_BOUND_FLAG in gss flags if
the CBs are present and matching.

Change license to the more permissive ISC

This change is not sudden, I have been thinking about relicensing this
project for quite a while.
The main trigger is that I received a couple of requests for a more
permissive license, but the real reason is that I always felt it at
odds that a module that is targeted to be loaded by MIT/Krb5's gssapi
library had such a widely different license.
It may give rise to misunderstandings as well as create undue burden
on users to figure out license compatibility with their applications
(proven in fact by the requests to relicense).

Do not require cached users with winbind

When acquiring credentials we may need to know if a cache is available.
This is necessary in the ISC cacse as we need to use those cached
credentials to perform NTLM authentication. However in the ASC case
we do not need creds of the user to be cached, all we need is a handle
that can be used to later authenticated the user against a DC.

Support get_sids request via name attributes

To allow server to get details about authenticated user
new get_sid request by "urn:gssntlmssp:sids" name attribute
is implemented (see RFC6680) to report the list of user SIDs.
The list of SIDs is stored in gssntlm source_name
(part of gss context, can be get by gss_inquire_context)
in textual representation - comma-separated list of SIDs.
gss_get_name_attribute() and gssntlm_inquire_name()
should be used to inquire name attributes.

Unit-test for get_sids name attributes:
Test is checking memory management for name attributes
with gss_duplicate_name, gss_release_name and
gss_get_name_attribute / gss_inquire_name API
for accessing name attributes
in both textual and binary representation.

Move attribute names to allocated strings

Unfortunately as our interfaces allow for importing and exporting the
gssntlmssp context via serialization we need to use allocated strings or
fixed size buffers.

In this case, given the attribute names are arbitrary strings I prefer
to allocate the names for ease of handling.
The bulk of the data for sids is in the values anyway so it is a small
price to pay to have a strdup() for the attribute name.

Adjust serialization for name attributes

This allows us to serialize and import back also named attributes.

NOTE: this commit also fixes a few severe export_data_buffer reallocation
bugs that so far flew under the radar because the initial allocation
size (4k) was big enough to contain the context as used in tests.
Larger contexts caused failures in the code that were also hard to
diagnose.

Use thread local storage for winbind context

This allow multiple calls into winbindd from parallel threads without
suffering from a common mutex that serializaes all authentications.

The price to pay is that a new context is allocated for each thread, and
the way windbind works, this probably mean a separate file descriptor is
created for each of this thread on the application side (winbindd will
be ok as it will kick idle connections).

The users of gssntlmssp in a multi-threaded environment will need to be
careful to limit the number of threads they allow to use gssapi in this
case.
