Pau Espin ac81d2789a lchan: Avoid applying transition changes if state new==old 
Let's avoid running over state change conditions or even printing log
lines if there's no state change.

Pau Espin 03cb50f809 lchan: Setup early_rr_ia timer only once during init 
There's no need to re-setup it every time.

Mark the cb as static since its private to the module, and move it
above its use point so it can be referenced.

Vadim Yanitskiy e73516ed00 rsl_tx_rf_res(): separate interference AVG / band calculation 
It's cleaner from the architectural point of view to have the
interference measurements processed in a separate function.

Pau Espin 36bbf1c328 Move lchan,power_control related code from gsm_data.c to their own files 
We already have similar classification in osmo-bsc.

Pau Espin e525584f3a Move lchan,power_ctrl specific code from gsm_data.h to their own files 
Let's split all lchan and power_control specific stuff into their own headers,
it helps finding out data and operations available related to them.

We already have similar classification in osmo-bsc.

Neels Hofmeyr da7c56ab8e early IMM ASS: add configurable delay for RR IMM ASS 
During live testing, it has become apparent that some IMM ASS still fail
when sending the RR IMM ASS directly upon the target channel becoming
active.

Add a bit of delay after activation, to give some time for the channel
to light up for the MS. Default is 50ms.

Neels Hofmeyr f1312f9818 enable Early Immediate Assignment 
When an Immediate Assignment comes in targeting an lchan that is not yet
active, then hold back the RR Immediate Assignment until the channel
becomes active.

This allows the BSC to send the Immediate Assignment before first
waiting for the Channel Activation ACK, saving one Abis roundtrip, and
helping avoid double allocation on high latency Abis links.

Neels Hofmeyr 9faaf4ecf0 cosmetic: common ts_is_pdch() 
Have one common ts_is_pdch(), placed in lchan.c, since this file is pretty
empty and pretty close to ts. Publish in gsm_data.h.

Remove the if-style implementation from l1sap.c, and instead implement in a
switch statement.

This prepares for upcoming ts_is_pdch() usage in ph_data_req() for sysmo and
lc15.

Holger Hans Peter Freyther f4f69ee6fc lchan: Similar to OpenBSC use a set method to change the state 
By making all modifications through lchan_set_state we can easily
add code to verify the state transition.
