There is a risk that interfaces such as psock_ioctl/psock_setsockopt
will cause paramete to be not four-byte aligned after calculating the
offset, so align the length of the structure with parameters by four
bytes.

In previous versions, during the teardown phase, the "open_blockdriver" would call the "mtd proxy" causing the "file mtd" node to be registered in the ftl. " node is registered in ftl.
Therefore, we changed the behavior to find the corresponding inode by node name.

Add the Sim WiFi function, which can provide the wifi operating on nuttx sim emulator,
and support two modes that simulate wifi, HWSIM and RNC(real network card).
- In the HWSIM mode, we simulates two wlan interfaces. The wlan0 is STA and
the wlan1 is AP. The wlan0 can connect to the wlan1 in the nuttx simulator.
- In the RNC mode, we can use the same wlan interface name on the nuttx simulator
to control the connection behavior of the real wireless card.

convert from body coordinate system to right-hand
coordinate system.
Example:
Compared to the standard coordinate system,
the x-axis and y-axis are interchanged and have opposite directions,
the z-axis remains normal.
body coordinate ----> right-hand coordinate
+x +y
| |
| |
| |
| |
-y<-------. .------>+x
/ /
/ /
/ /
/ /
+z +z
So for the above conversion, using "P3" to represent transformation relationships
The front is 1 0 2, which represents the y x z axis.
The standard order is 0 1 2, so y and x are interchanged.
The following -1 1 1 indicates the direction of the axis.
The standard is 1 1 1. Because the current y-axis is opposite to
the standard x-axis, it is -1.
static const struct sensor_axis_map_s g_remap_tbl[] =
{
{ 0, 1, 2, 1, 1, 1 }, /* P0 */
{ 1, 0, 2, 1, -1, 1 }, /* P1 */
{ 0, 1, 2, -1, -1, 1 }, /* P2 */
{ 1, 0, 2, -1, 1, 1 }, /* P3 */
{ 0, 1, 2, -1, 1, -1 }, /* P4 */
{ 1, 0, 2, -1, -1, -1 }, /* P5 */
{ 0, 1, 2, 1, -1, -1 }, /* P6 */
{ 1, 0, 2, 1, 1, -1 }, /* P7 */
};
you can call the function sensor_remap_vector_raw16 and pass P3 parameters
to perform the conversion.

When the application calls poll and returns the POLLIN event,
QPOLL will be called again during the read operation,
causing rx_length to change and data to be lost.
Therefore, read only need to actively call qpoll to collect driver

the difference between the generation and the mainline generation

A dead lock may happen before this patch:
rptun thread (usrsock_rpmsg_recvfrom_handler):
Gets all tx payload but waiting net_lock in psock_recvfrom
net driver thread (higher priority):
Receives a packet, holding net_lock, calling usrsock_rpmsg_send_event
But no tx buffer left, so rpmsg_send blocks, and won't release net_lock
In short:
Rptun: Hold all `tx_payload_buffer` -> want `net_lock`
Driver: Hold `net_lock` -> want `tx_payload_buffer`
This patch use net_lock to combine get_tx_payload and recvfrom together,
then:
- If it's waiting net_lock, tx payload will not be held, other threads
may get tx buffer and do their work.
- If net_lock is got, it won't be disturbed before finish receiving,
then tx payload won't have chance to be blocked before releasing.
