Code in oml.c, upon receiving net attributes, merges the new attributes
with old ones (for some reason I don't really know). Hence, if we
disconnect from a BSC and go to NOT_INSTALLED state, we must free
previous nm_attr in order to avoid mixing them once we connect to a new
(potentially different) BSC upon reconnect.

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.

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.

lower layer specific APIs require first to enable the TRX object
(GsmL1_PrimId_MphInitReq, which requires ARFCN received during Set
Radio Carrier Attributes) before enabling the per-TS structure.
Hence, OPSTART must happen in RCARRIER MO before OPSTART can be sent to
the Radio Channel MOs, otherwise the initialization of the TS objet will
fail and OPSTART for the RadioChannel MO will send back a NACK.
In order to avoid this, we need to keep the RadioChannel MO announced as
"Disabled Dependency" until RCARRIER is OPSTARTed.

All the Operative State logic to manage a RadioCarrier//BBTransc NM objects is
centralized in these FSM, where other parts of the code simply send
events to it.
This allows keeping state consistent and offloading logic from each bts
backend, since they are only required to submit events now.
The idea in the long run is to also replace other NM objects with
similar FSMs.
This improved logic fixes bug where PHY + RSL link became available before
OPSTART and hence op state changed to Enabled before receiving any OPSTART message.
