    tcpconns plugin: add support for AIX
    
    Hi.
    
    In AIX there is a undocumented function/syscall in libc: netinfo
    returns a structure with the state of the tcp connections.
    
    I didn't found the description or info abut this syscall,  I guess is
    something like this:
    
    int netinfo (int proto, void *data, int *size,  int n);
    
    and the struct something like this: (with some work we can guess the
    unknow remaining bytes)
    
    struct netinfo_header {
            unsigned int proto;
            unsigned int size;
            struct netinfo_entry e[];
    };
    struct netinfo_entry {
            uint32_t unknow1;
            uint32_t unknow2;
            uint16_t dstport;
            uint16_t unknow3;
            struct in6_addr dstaddr;
            uint16_t srcport;
            uint16_t unknow4;
            struct in6_addr srcaddr;
            uint32_t unknow01[4];
            uint32_t unknow02[2];
            uint16_t so_options;
            uint16_t unknow02a;

            uint16_t so_dqlen;
            uint32_t unknow03[4];
            struct {
                    uint32_t sb_hiwat;
                    uint32_t unknow01;
                    uint32_t unknow02;

            uint32_t unknow08[2];
            uint32_t unknow09;
            struct {
                    uint32_t sb_hiwat;
