This adds and uses the gensec_spnego_neg_loop() abstraction, which
abstracts start, step and finish hooks.
The start hook does the initial processing on the incoming paket and
may start the first possible subcontext. It indicates that
gensec_update() is required on the subcontext by returning
NT_STATUS_MORE_PROCESSING_REQUIRED and return something useful in
'in_next'. Note that 'in_mem_ctx' is just passed as a hint, the
caller should treat 'in_next' as const and don't attempt to free the
content. NT_STATUS_OK indicates the finish hook should be invoked
directly withing the need of gensec_update() on the subcontext.
Every other error indicates an error that's returned to the caller.
The step hook processes the result of a failed gensec_update() and
can decide to ignore a failure or continue the negotiation by
setting up the next possible subcontext. It indicates that
gensec_update() is required on the subcontext by returning
NT_STATUS_MORE_PROCESSING_REQUIRED and return something useful in
'in_next'. Note that 'in_mem_ctx' is just passed as a hint, the
caller should treat 'in_next' as const and don't attempt to free the
content. NT_STATUS_OK indicates the finish hook should be invoced
directly withing the need of gensec_update() on the subcontext.
Every other error indicated an error that's returned to the caller.
The finish hook processes the result of a successful gensec_update()
(NT_STATUS_OK or NT_STATUS_MORE_PROCESSING_REQUIRED). It forms the
response pdu that will be returned from the toplevel gensec_update()
together with NT_STATUS_OK or NT_STATUS_MORE_PROCESSING_REQUIRED. It
may also alter the state machine to prepare receiving the next pdu
from the peer.
This is the start of using this abstraction for the initial client or server
start with on empty input token from the peer.
This abstraction will be applied to all four other spnego states,
gensec_spnego_{client,server}_negToken{Init,Targ}() in the following
commits.

This is the second part for the issue from commit 8bb4fccd. A KDC that
does not return a PAC first triggers this message, then the "resorting
to local user lookup" one. Change the log level for the "obtaining PAC
via GSSAPI gss_get_name_attribute" message as well to avoid spamming the
logs during normal usage. While changing this message, also remove the
discard_const since it is no longer required.

[MS-SPNG] requires the NTLMSSP RC4 states to be reset after

The 'reset_full' parameter is needed to support the broken
behavior that windows only resets the RC4 states but not the
sequence numbers. Which means this functionality is completely
useless... But we want to work against all windows versions...
