1. fs_epoll: try again when epoll_teardown() return 0
when poll_notify() called larger than twice when epoll_wait() blocked
in the eph->sem, the semcount will be larger than 1 when epoll_wait()
unblocked and will return 0 directly at the next epoll_wait.
So retry to wait the eph->sem again when epoll_teardown return 0.
2. fs_epoll: poll_setup the fd again even this fd got non-expected event
Some poll implementations need call poll_setup again when their internal
states changed (e.g., local socket), so should add the fd to the epoll
teardown list and poll_setup again at the next epoll_wait even this fd
got the user non-expected event.

Handle task spawn attributes as task spawn file actions are handled.
Why? This removes the need for sched_lock() when the task is being
spawned. When loading the new task from a file the scheduler can be
locked for a VERY LONG time, in the order of hundreds of milliseconds!
This is unacceptable for real time operation.
Also fixes a latent bug in exec_module, spawn_file_actions is executed
at a bad location; when CONFIG_ARCH_ADDRENV=y actions will point to the
new process's address environment (as it is temporarily instantiated at
that point). Fix this by moving it to after addrenv_restore.
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.

This commit adds support for custom stream via fopencookie function.
The function allows the programmer the create his own custom stream
for IO operations and hook his custom functions to it.
This is a non POSIX interface defined in Standard C library and implemented
according to it. The only difference is in usage of off_t instead of
off64_t. Programmer can use 64 bits offset if CONFIG_FS_LARGEFILE is
enabled. In that case off_t is defined as int64_t (int32_t otherwise).
Field fs_fd is removed from file_struct and fs_cookie is used instead
as a shared variable for file descriptor or user defined cookie.
The interface will be useful for future fmemopen implementation.

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

Channel polarity can now be set with PWMIOC_SETCHARACTERISTICS ioctl

polarity can be easily set from application layer for each channel
apart and also can be change on at runtime if required (although this is
not likely).

Allows the debug behavior to be specified as part of the board, architecture or chip configuration. This is useful when using out-of tree custom board configurations.
Documentation for PWMIOC_SETCHARACTERISTICS ioctl command mentioned
that this command will neither start nor stop the pulsed output. This
however is incorrect as PWMIOC_SETCHARACTERISTICS command leads to
pwm_start() function which starts the pulsed output.
While this might not be the correct behaviour (I would probably welcome
the option to set PWM characteristics without starting the pulsed output)
it is the way the PWM driver is coded for many architectures. Future
enhancement might be to add function pwm_setchar() for example to just
set characteristics without starting the PWM output.
