this allows us to remove a dependency on the dcerpc_server from code
that uses rpc forwarding
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

Windows 2000 does strictly request header signing on some requests also if the
server doesn't provide it. But there is a small trick (don't reset the actual
session info) to make these special RPC operations work without a full header
signing implementation.
This fixes for example the list of domain groups in local groups when displayed
sing the local user/group management tool.
And this should finally fix bug #7113.
The patch was inspired by another one by tridge and abartlet: http://gitweb.samba.org/samba.git/?p=tridge/samba.git;a=commitdiff;h=2dc19e2878371264606575d3fc09176776be7729
The recent dcerpc padding changes made our padding relative to the
packet header, instead of the start of the stub. Surprisingly, this
broke w2k8r2 doing a dcpromo join to a s4 server. It seems that w2k8r2
is very fussy about the padding it gets in some circumstances.
Cope with a wider range of auth padding in dcerpc bind_ack and
alter_context packets. We now use a helper function that calculates
the right auth padding.
When starting GENSEC on the server, the auth subsystem context must be
passed in, which now includes function pointers to the key elements.
This should (when the other dependencies are fixed up) allow GENSEC to
exist as a client or server library without bundling in too much of
our server code.

Also ignore auth trailers in level connect on receive.
This fixes [krb5,connect] against windows.
TODO: maybe the gensec mech need to decide if signatures
are needed in level connect.

Break up auth/auth.h not to include the world.
Add credentials_krb5.h with the kerberos dependent prototypes.

The server side change is needed to fix a valgrind error, which was
possibly exploitable if the client sent deliberately bad data

length, use the amount the wapped message expanded by.
This works, because GSSAPI doesn't do AEAD (signing of headers), and
so changing the signature length after the fact is valid.

authentication. This pulls the creating of the keytab back to the
credentials code, and removes the special case of 'use keberos keytab
= yes' for now.
This allows (and requires) the callers to specify the credentials for
the server credentails to GENSEC. This allows kpasswdd (soon to be
added) to use a different set of kerberos credentials.
The 'use kerberos keytab' code will be moved into the credentials
layer, as the layers below now expect a keytab.
We also now allow for the old secret to be stored into the
credentials, allowing service password changes.

data to be signed/sealed. We can use this to split the data from the
signature portion of the resultant wrapped packet.
This required merging the gsskrb5_wrap_size patch from
lorikeet-heimdal, and fixes AES encrption issues on DCE/RPC (we no
longer use a static 45 byte value).
This fixes one of the krb5 issues in my list.

(This used to be commit e4f2afc343)
event_context for the socket_connect() call, so that when things that
use dcerpc are running alongside anything else it doesn't block the
whole process during a connect.
Then of course I needed to change any code that created a dcerpc
connection (such as the auth code) to also take an event context, and
anything that called that and so on .... thus the size of the patch.
There were 3 places where I punted:
- abartlet wanted me to add a gensec_set_event_context() call
instead of adding it to the gensec init calls. Andrew, my
apologies for not doing this. I didn't do it as adding a new
parameter allowed me to catch all the callers with the
compiler. Now that its done, we could go back and use
gensec_set_event_context()
- the ejs code calls auth initialisation, which means it should pass
in the event context from the web server. I punted on that. Needs fixing.
- I used a NULL event context in dcom_get_pipe(). This is equivalent
to what we did already, but should be fixed to use a callers event
context. Jelmer, can you think of a clean way to do that?
I also cleaned up a couple of things:
- libnet_context_destroy() makes no sense. I removed it.
- removed some unused vars in various places
