agch: Manage AGCH queue length
Currently, the AGCH queue length is not limited. This can lead to
large delays and network malfunction if there are many IMM.ASS.REJ
messages.
This patch adds two features:
- Don't accept msgs from the RSL layer when the queue is way too
full (safety measure, mainly if bts_ccch_copy_msg() is not being
called by the L1 layer, currently hard coded to 1000 messages)
- Selectively drop IMM.ASS.REJ from the queue output depending on the
queue length
