faluco 55f5f74ff3 Fixed case where calling gw::setup_if_addr after ue attachment would spawn a new thread without closing the current one. 
This would end up being a resource leak as the number of threads grow forever until the application crashes.

Andre Puschmann 26cc6d7886 ue: remove stack type parameter 
for the moment we always use the LTE stack (also for NSA mode).
For SA we likely pick a smarter approach to pick the stack type, i.e.
using the ARFCN specified in the config.

Andre Puschmann cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3 
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.

Andre Puschmann 99dc94ab38 nas: make state variables atomics 
NAS states and substates maybe be requested from other threads so
they need to be protected.

Note that the caller still needs to hold it's own mutex if different
actions are required based on the state.

remove the code from now.

connection release.
