Having the lifetime of the encoded claims be tied in a predictable
fashion to a caller‐controlled memory context is less prone to error.

The new ‘claims_data’ structure can store claims in three different
representations — as an encoded blob, as a CLAIMS_SET structure, or as a
series of CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1 claims. Given a set of
claims, the accompanying functions provide a way to convert them into
the desired format.

Some functions in the auth_session subsystem will need to be able to
call encode_claims_set(). Moving said function lets them do that whilst
avoiding circular dependencies and additional public dependencies.

samba_kdc_get_pac_blobs() passes a pointer to a user_info_dc structure
obtained from samba_kdc_get_user_info_from_db() into
samba_add_asserted_identity(). The latter function modifies the SIDs of
the user_info_dc structure in order to add the Asserted Identity SID,
but samba_kdc_get_user_info_from_db() actually caches that structure
internally, meaning that subsequent calls will return the modified
structure.
We should not modify cached SIDs, so have
samba_kdc_get_user_info_from_db() return a pointer to constant data, and
copy the returned array of SIDs before adding the Asserted Identity SID.

This changes the structure being used to convey the current user state
from the netlogon-derived 'netr_SamInfo3' structure to a purpose-built
structure that matches the internals of the Samba auth subsystem and
contains the final group list, as well as the final privilege set and
session key.
These previously had to be re-created on the server side of the pipe
each time.

This changes auth_serversupplied_info into the IDL-defined struct
auth_user_info_dc. This then in turn contains a struct
auth_user_info, which is the only part of the structure that is
mainted into the struct session_info.
The idea here is to avoid keeping the incomplete results of the
authentication (such as session keys, lists of SID memberships etc) in
a namespace where it may be confused for the finalised results.

This will be a building block for a tokenGroups test, which can
compare against a remote server (in particular the rootDSE) against
what we would calculate the tokenGroups to be.
(this meant moving some parts out of the auth_sam code into the
containing library)

And remove the now obsolete one for "struct tevent_context"

This allows us to control what groups should be added in what use
cases, and in particular to more carefully control the introduction of
the 'authenticated' group.
In particular, in the 'service_named_pipe' protocol, we do not have
control over the addition of the authenticated users group, so we key
of 'is this user the anonymous SID'.
This also takes more care to allocate the right length ptoken->sids
Andrew Bartlett
The auth context was in the past only for NTLM authentication, but we
need a SAM, an event context and and loadparm context for calculating
the local groups too, so re-use that infrustructure we already have in
place.
However, to avoid problems where we may not have an auth_context (in
torture tests, for example), allow a simpler 'session_info' to be
generated, by passing this via an indirection in gensec and an
generate_session_info() function pointer in the struct auth_context.
In the smb_server (for old-style session setups) we need to change the
async context to a new 'struct sesssetup_context'. This allows us to
use the auth_context in processing the authentication reply .
Andrew Bartlett
This should always return a simple structure with no need to consult a
DB, so remove the event context, and simplfy to call helper functions
that don't look at privilages.

This patch adds a system_session cache, preventing us from having to
recreate it on every ldb open, and allowing us to detect when the same
session is being used in ldb_wrap
The purpose of admin_session is to be able to execute parts of provisioning
as the user Administrator in order to have the correct group and owner in the
security descriptors. To be used for provisioning and tests only.
