gb_proxy: Rename gbproxy_peer to gbproxy_bvc
I cannot really read the code while it contains its historical weird naming. A "peer" used to be a strange amalgamation of NSE + BVC, while in reality we can have any number of BVC on top of each NSE. We recently started to split the peer into a gbproxy_nse_peer + gbproxy_peer. This takes it one step further and renames gbproxy_peer to gbproxy_bvc, as that's really what it is.
