9881fbae28 tools/gdb: fix thread command not working 
`thread` is a GDB prefix command. Use `define` can only change it to a
user prefix command. In this case, `thread 3` is unable to pass
the argument 3 to python.

Use python code to register command to overwrite this behavior. It may
not work with future GDB, but all is good for now.

0cda6278d3 tools/gdb: Use ptr's value instead of ptr's adderess in container_of 
We're using `ptr.cast(get_long_type())` a week ago to get the pointer's value, it's alright, but `ptr.address` is not, the `ptr.address` will return **the address of the pointer**.

These values are the address of first element in the queue:
    - `int(g_sigfreeaction["head"])`
    - `g_sigfreeaction["head"].cast(get_long_type())`
    - `g_sigfreeaction["head"].dereference().address`
But:
    `int(g_sigfreeaction["head"].address)` is the address of the "head" member, which equals to the address of `g_sigfreeaction`

It's happening in NxSQueue:
    g_sigfreeaction = gdb.parse_and_eval("g_sigfreeaction")
    print(["%x" % (node) for node in NxSQueue(g_sigfreeaction)])
    print(["%x" % (node) for node in NxSQueue(g_sigfreeaction, "sigactq_t", "flink")])

a4e5689c7f tools/gdb: Allow utils.container_of with str input 
After we introduced NxDQueue and NxSQueue, we're using them like `NxDQueue(g_active_connections, "struct socket_conn_s", "node")` and leads to `utils.container_of(ptr, str, str)`, so maybe we need to allow str input for `utils.container_of`
