Harald Welte (local) 3e46031f52 Introduce new ACT_REQ state to prevent race condition during channel allocation 
When we allocate a channel, we send the RSL CHAN ACT REQ and wait until we get
a CHAN ACT ACK.  Only the ACK will change the state, so there is a race where
we allocate that same channel to a different channel request before we get
the ACT ACK.

Introducing a new ACT_REQ state resolves this issue.

About OpenBSC
=============

OpenBSC is a minimalistic implementation of the GSM Network, with particular
emphasis on the functionality typically provided by the BSC, MSC, HLR, VLR.

Its only current interface is a mISDN based E1 interface utilizing the A-bis
protocol between BSC and BTS.  In other words, you can connect an existing
GSM Base Transceiver Station (BTS) through E1 to OpenBSC.

So far, it has only been tested with the Siemens microBTS BS-11.  Test reports
with other BTS are appreciated!

This project is still in its early days, and there are lots of areas where it
doesn't behave as per GSM spec.
