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")])
Without this patch:
    ['f3c0aa10', 'f3c0aa2c', 'f3c0aa48']
    ['55db90a0', 'f3c0aa10', 'f3c0aa2c']
With this patch:
    ['f3c0aa10', 'f3c0aa2c', 'f3c0aa48']
    ['f3c0aa10', 'f3c0aa2c', 'f3c0aa48']

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`

d8eccbc0f2 gdb/lists: add foreach array command to dump array 
This command can dump any array with auto length detection or specified
length.

An optional `element` parameter is used to only dump this element in
array when array is in type of struct.

E.g.

(gdb) foreach array g_mmheap->mm_nodelist
0: {preceding = 0, size = 0, pid = 0, seqno = 0, backtrace = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, flink = 0x41692cb8, blink = 0x0}
1: {preceding = 0, size = 0, pid = 0, seqno = 0, backtrace = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, flink = 0x40c378a0, blink = 0x40605f58}

(gdb) foreach array g_mmheap->mm_nodelist -e "flink"
0: 0x41692cb8
1: 0x40c378a0

cd3d639153 gdb/lists: optimize foreach list command 
NuttX has various of list implementation, but the core of list is to
find next node, and stop iteration.

This change addes parameter of how to get next node by specifying its
element name.

Note the list head must be a pointer type.
E.g.
(gdb) foreach list -n next &g_msgfree

(gdb) foreach list "(struct list_node *) 0x40286e30"
0: {prev = 0x40286200 <g_msgpool+280>, next = 0x4028628c <g_msgpool+420>}

e7c2e7c576 tools/gdb: use remote-register standard 
GDB uses remote-register to describe g/G packet. Whatever the target is,
we can always find out the register offset in packet by `maint print
remote-registers`.

In NuttX, we follow the same standard to prepare the packet, in both
coredump and GDB stub.

For example, the CPSR for arm-v7a is at register number of 25, byte
offset of 164. So we define the CPSR in g_reg_offs (164 /4 = 41)th
elementent.

If GDB stub supports qXfer feature, then GDB will ask stub for target
descriptor, which is a standard xml file. If this file is provided, then
the register order is also changed. It's also reflected in 'maint print
remote-registers' output. JLink GDB server supports it for example.

We always use manually added second inferiort to query the original
remote register layout. So it can match with tcbinfo.
