Added __format__ method to support format spec like {:>10} that gdb.Value doesn't support. For such case, gdb.Value is converted to python value firstly and then format natively.
Override all methods/attributes could return gdb.Value to return utils.Value instead.

Use a class Bactrace to support convert address to backtrace, format to string, accessing element and iterate though them.
Adjust usage in fs and addr2line to make full use of it.

1. Support any type of value as pointer address in container_of
2. Support string as type in offset_of
3. Make sure type is a pointer in container_of, and not a pointer in
offset_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")])

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`

Use json module to save macro info to json file and load directly. It can save 2seconds for x4b projects to load plugin
