Harald Welte a7263b6474 Fix license headers.
We have licensed the code under GNU Afffero Public License,
and state that in the first paragraph as well as in the link
to the license.  However, a paragraph in the middle stated
"see the GNU General Public License", which is somewhat misleading.

Let's fix that.

Pau Espin 6be13437b7 Merge gsm_network into gsm_bts_sm and place gsm_bts under it
This way the data model in TS 12.21 (Figure 1) is followed, where
there's a BTS Site Manager containing one or more BTS. In our case we
only support 1 BTS (cell) so far.

Pau Espin cea6c230ad nm: Apply OPSTART through NM FSMs
This way we have further control on how to handle the OPSTART messages
received. For instance, NACK them if the NM object FSMs are not at the
expected correct state.

Pau Espin aebd2a21b5 nm: Drop NM_EV_SETATTR_{ACK/NACK}
Simply return error codes from lower layer implementations, and do
the OML handling in the common NM TS 12.21 FSMs.

As a result, we simplify the logic in the lower layers.

Pau Espin c4a17d35ec nm: Apply BTS/TRX/TS OML Attributes through NM FSMs
This way we have further control on how to handle the SetAttr meessages
received. For instance, NACK them if the NM object FSMs are not at the expected
correct state.

The originating msgs are now kept owned and freed by the OML layer
(oml.c), and the NM FSMs only uses them and create new OML msgb when
answering with ACK/NACK.

Pau Espin 68a39a8617 nm_*fsm: Make FSMs aware of object being properly configured or not
This will allow in the future advertising children objects that the
parent object has been configured. It is useful for instance to let TRX
know that the BTS is configured.

Pau Espin ea53ad454e Allow setting administrative state through oml_mo_state_chg()
This way it can be changed together with operative/availability state,
and changes announced to the BSC if present.

This commit presents no real change in osmo-bts behavior, since the only
place where adm_state is passed different than -1 is in
st_op_disabled_notinstalled_on_enter(), which is actually never called
(yet) since it's the initial state and no other states transition later
to it.

However, this will change in the future once we support re-connecting to
a (possibly different) BSC, which means objects will need to be moved to
that state to restart the whole OML install procedure on the new BSC.

Pau Espin 88fe4b079d Introduce NM BTS Site Manager FSM
This fixes old behavior mimicing broken behavior in nanoBTS (according to TS 12.21)
where BTS Site Mgr NM object was announced as Enabled despite no OPSTART
was sent by the BSC.
With this new FSM, BTS SiteManager will be announced as Disabled Offline
during OML startup conversation, instead of Enabled.

The new osmo-bsc OML management FSMs use this change in behavior to find
out whether it should use the old broken management states (without
Offline state, as per nanoBTS) or use the new state transitions (which
allow fixing several race conditions).
