gprs: Store gbproxy patching state per peer
Currently, all patching state is stored globally in the gbproxy. Thus
the feature cannot be used safely with a concentrating gbproxy (NAT).
This patch moves the state and relevant counters to the gbprox_peer
structure. It adds code to resolve the corresponding peer when
packets are received by looking at BVCI, NSEI, and BSSGP IEs (BVCI,
RAI/LAI/LAC) when the peer is not passed to the
gbprox_patch_bssgp_message() function.
Test cases are also added for the SGSN->BSS case including test cases
with invalid identifiers.
Note that this patch should make it possible to use RAI patching at a
NAT gbproxy as long as the messages are not encrypted.
