BBS 会话信息

BBS的用户相关的东西。这块非常复杂，分成好几个部分。

UTMP

UTMPHEAD

struct UTMPHEAD {
    int next[USHM_SIZE];
    int hashhead[UTMP_HASHSIZE + 1];    /* use UCACHE_HASHSIZE/32 */
    int number;
    int listhead;
    int list_prev[USHM_SIZE];   /* sorted list prev ptr */
    int list_next[USHM_SIZE];   /* sorted list next ptr */
    time_t uptime;
};

static struct UTMPHEAD *utmphead;

utmphead其实指向一块shared memory，key = UTMP_SHMKEY

UTMPHEAD结构/数据由UtmpHead类处理，全都为GetXXX/SetXXX形式。
