Jacob Erlbeck 5e6d679df3 gb: Fix gprs_ns_rx_reset to not create NS-VC duplicates
Under special circumstances (see below) receiving a NS-RESET leads to
duplicated NS-VC entries.

This happens when the source port of a NS-VC changes to a new one
that has already been used by another NS-VC.

This patch changes gprs_ns_rx_reset() to check for this case and to
use the existing NS-VC object. The NS-VC object that was associated
with the source address before is detached from this source but kept
in the NS-VC list so that it can be reattached when a correspondent
NS-RESET is received later on. Meanwhile it will have a cleared link
layer address which will not match a real link info.

A new counter NS_CTR_REPLACED is incremented each time when the NS-VC
object is replacing another one. A new signal S_NS_REPLACED is added
which gets dispatched in this case, too.

Another new counter NS_CTR_NSEI_CHG is incremented each time when the
NSEI of a NS-VC object (with fixed NSVCI) changes.
