It was described in [1] that the NM FSM failed to trigger the
S_NM_RUNNNG_CHG signal when locking/unlocking the TRX.
That's because current osmo-bts doesn't fully conform to TS 52.021 and
it doesn't go back to Op=Disabled Avail=Dependency when becoming
Admin=Locked. It's true though that TS 52.021 sec 5.3.1 is not really
helpful since it doesn't explicitly state that specific object should go
into Disabled Dependency, despite saying it for most of the other ones.
Hence, let's account for both possibilities at the BSC side.

Since b7ef6884f9, the state is updated
before triggering the signal S_NM_STATECHG, so the warning does no
longer hold true.

This allows different parts of the code to hook to some signals which
allow start/stopping processes based, for instance, on whether C0 is
available or not.
This can be later used by paging or CBSP code. Also ACC code can be
ported to this new system (acc_ramp_nm_sig_cb()).
Same signal can be used for other NM objects, but is left unimplemented
until there's use for them.

There's no need to use pointers there, it is only asking for errors from
code handling the data structe from the signal by attempting to change
them. Even for mem size point of view it doesn't make sense, since it's
3 byte vs a 4 byte pointer.
Furthermore, this is a preparation for new commit, where the NM object
current state will be updated before emitting the signal. This patch
eases a lot the follow up mentioned patch.

This makes sure code accessing those fields is not changing its values,
since it would make no sense to change those. Follow up commit will make
convert those pointers to be full structs instead, as there's no need to
have pointers there.

Its name is totally misleading, since they seem to be related to
GetAttributes messages rather than SetAttributes.

Older osmo-bts versions (before FSMs) tended to mimic broken behavior
from nanoBTS. As so, we detect it because SiteMGr becomes Enabled by
default as in nanoBTS, and hence we can manage them also by expecting no
Offline state and sending Opstart (and hence finally transitting to
Enabled) during Dependency state.
