si: Add a config option to disable SI2ter/SI2bis/SI5ter/SI5bis messages
The iPhone5 (US) appears to have some issues with the SIs generated,
or the nanoBTS is not sending them correctly.
Add a configurable hack to put all bands into the SI2/SI5 message.
It is enabled by the bts VTY command 'force-combined-si'.
This is a quick change without much reflection and watching for side
effects. I have verfied that a network with ARFCN 134 and neighbors
ARFCN 130 and 512 do not get generate the SI2ter and announce everything
inside the SI2.
This patch is conceptually based on 'si: Add a hack to disable
SI2ter/SI2bis/SI5ter/SI5bis messages' (692daaf2d2).
