Module Name:    src
Committed By:   ozaki-r

        src/sys/net: bridgestp.c if_bridge.c if_bridgevar.h

Log Message:
Simplify bridge(4)

Thanks to introducing softint-based if_input, the entire bridge code now
never run in hardware interrupt context. So we can simplify the code.

- Remove spin mutexes
  - They were needed because some code of bridge could run in
    hardware interrupt context
  - We now need only an adaptive mutex for each shared object
    (a member list and a forwarding table)
- Remove pktqueue
  - bridge_input is already in softint, using another softint
    (for bridge_forward) is useless
  - Packet distribution should be down at device drivers
