By setting the event context to use for this operation (only) onto
the krb5_context just before we call that operation, we can try
and emulate the specification of an event context to the actual send_to_kdc()
This eliminates the specification of an event context to many other
cli_credentials calls, and the last use of event_context_find()
Special care is taken to restore the event context in the event of
nesting in the send_to_kdc function.

Allow using both pyembed and pyext, to prevent unresolved symbols.

this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

This is needed to remove samba specifc symbols from the bundled
ldb, in order to get the ABI right.

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

multiple event contexts
It is NEVER valid to free an event context that anybody else may have
a reference to, and never normally valid to have two 'live' at once.
We must instead call tevent_re_initialise() to wipe clean an existing
pointer.

This will fork off exactly one child to handle some task, ensuring
that if it dies or changes global state, that this does not change
everything.

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 .

We need to be able to give sensible error messages when a kerberos
calls fails. This propogates the kerberos error up the stack to the
caller.

This reverts commit 69d5cea2e5.
This commit causes issues with the RPC server, revert it until we find the
exact issue and possibly have a torture test to avoid it happening again.
Found playing with w2k8r2 and forest trusts.
After looking at the s4 side of the (s)channel :) I found out that it makes
more sense to simply make it use the tdb based code than redo the same changes
done to s3 to simplify the interface.
Ldb is slow, to the point it needs haks to pre-open the db to speed it up, yet
that does not solve the lookup speed, with ldb it is always going to be slower.
Looking through the history it is evident that the schannel database doesn't
really need greate expanadability. And lookups are always done with a single
Key. This seem a perfet fit for tdb while ldb looks unnecessarily complicated.
The schannel database is not really a persistent one. It can be discared during
an upgrade without causing any real issue. all it contains is temproary session
data.
We need to free the lp_ctx after we free the event context, otherwise
the teardown code in the notify backend dies when it tries to use the
iconv_convenience ptr
Fixes bug 7053
This task watches for changes in the list of DCs, and creates a bind9
formatted file that grants update permission to all DCs, plus to the
administration, and machines update for their own names.

A KCC is a 'Knowledge Consistency Checker', a fancy name for a daemon
that works out who will replicate with who in a AD domain. This
implements an extremely simple KCC task that just wants to replicate
with everyone :-)
Previously we relied on process groups and SIGTERM to ensure that
child tasks died in the standard process model when the parent task
died. This doesn't work when the server is run in interactive mode, as
in that case we don't call become_daemon() and don't get a separate
process group.
The fix is to have a pipe held open by the parent server process, and
inherited by child tasks. If the parent exits then the write side of
the pipe is implicitly closed, which causes an event in the child
tasks that causes them to exit
While testing the use of the standard process model with 'make test' I
found that testing was much slower (by several times) with the
standard model than with the single model. The primary problem was
that each SMB connection would open a new sam ldb context, and all of
those would reload the full AD schema.
The fix is to pre-open the SAM during server startup, before any child
processes are forked. This sets up the global schema context which is
inherited by all connections.
The standard model is still slower at make test than the single model,
but not by nearly as much. I am working on further reducing the gap.
For now implement just a very simple protocol
to negotiate the transport session info.
We may need to pass more info later,
e.g. client ip or name...
