Daniel Willmann ac8536da54 gb_proxy: Ensure cell info is up to date when receiving PTP-BVC reset 
When a BSS resets its BVC and reuses a BVCI with a differente cell id
the SGSN BVC still has the old cell information.

This results in the SGSN receiving a BVC reset for the old cell which in
turn leads to all sorts of issues (probably also with paging) and
conflicting information since the cell info is also present in the
UL-UNITDATA and this is just passed through from the BSS.

Instead of reusing the old BVC on the SGSN side free any existing and create
new ones.

About osmo-gbproxy

osmo-gbproxy is a proxy for the Gb interface within the 3GPP GERAN (GPRS/EDGE RAN) architecture. It is part of the Osmocom Open Source Mobile Communications projects.

It allows you to aggregate many Gb links/connections into one. It also has the ability to convert between different Gb interface protocol stacking, such as from Gb-over-FrameRelay to Gb-over-IP.

Until 2021 it used to be part of the osmo-sgsn git repository, and before that (until 2017) part of openbsc.git
