[lac] Do not use the reserved LAC 0x0 for two different things

We are using LAC=0 for remembering that a GSM subscriber is
detached. I recently added code to gsm_bts_by_lac that will
return every BTS in case the lac is 0. Harald highlightes
that we would now search for detached subscribers at every
BTS of our network which is clearly not what we want.

Introduce two defines for the two reserved LAC, add a
pointer to the specification, check that our config files
do not contain these reserved values, use the define
and change gsm_bts_by_lac to use the other define.
