    [NET]: prot_inuse cleanups and optimizations · 65f76517

    1) Cleanups (all functions are prefixed by sock_prot_inuse)
    sock_prot_inc_use(prot) -> sock_prot_inuse_add(prot,-1)
    sock_prot_dec_use(prot) -> sock_prot_inuse_add(prot,-1)
    sock_prot_inuse()       -> sock_prot_inuse_get()
    New functions :
    sock_prot_inuse_init() and sock_prot_inuse_free() to abstract pcounter use.
    2) if CONFIG_PROC_FS=n, we can zap 'inuse' member from "struct proto",
    since nobody wants to read the inuse value.
    This saves 1372 bytes on i386/SMP and some cpu cycles.
