For unknown reason, for some cases, GDB refuses to read register using descriptor. Let's stick to the register name.

`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.

gdb.error could report if memory is corrupted. Save and report the exception and continue to next command.

Should use gdbinit.py instead of package __init__.py. Report the correct usage if user try to source the package directly.

1. The prev free flag should use field size instead of preceding to compare.
2. If not prev-free, then prevnode should be None.
3. Cast type to mm_freenode_s in order to access flink, blink when node is free.
4. Heap itself is also included in first region.

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`
