In order to ensure the detached thread obtain the correct return
value from pthread_join()/pthread_cancel(), the detached thread
will create joininfo to save the detached status after thread
destroyed. If there are too many of detached threads in the
process group, the joininfo will consume too much memory.
This is not friendly to embedded MCU devices.
This commit keep the semantics as #11898 was introduced,
will no longer save joininfo for detached threads to avoid wasting memory.

Because CAN is a broadcast protocol, each conn needs to be given independent data to avoid mutual interference.

The symmetric NAT limits one external port to be used with only one peer ip:port.
Note:
1. To avoid using too much #ifdef, we're always passing peer_ip and peer_port as arguments, but won't use them under full cone NAT, let the compiler optimize them.
2. We need to find port binding without peer ip:port, so don't add peer ip:port into hash key.
3. Symmetric NAT needs to *select another external port if a port is used by any other NAT entry*, this behavior is exactly same as Full Cone NAT, so we don't need to change anything related to `ipv4_nat_port_inuse`.

Extracting global variable information using scripts:
kasan_global.py:
1. Extract the global variable information provided by the -- param asan globals=1 option
2. Generate shadow regions for global variable out of bounds detection
Makefile:
1. Implement multiple links, embed the shadow area into the program, and call it by the Kasan module

iC-JX expander has NINT (not interrupt) pin that goes to logical zero
if interrupt occurs. This commit adds support for iC-JX options settings
that allows to enable the interrupt for defined input pins.
The interrupt is handled in HP worker thread to avoid waiting for SPI
transfers in interrupt context. Board has to configure interrupt event
for GPIO pin connected to NINT.

RTC data was not being correctly placed on RTC's memory data due to
linker issues. Also, the image's RTC memory segment was not being
properly parsed by the bootloader.
This is a high resolution PWM driver, utilizing one 16-bit Flex-IO timer for
generating PWM period and the rest of the timers to generate PWM duty cycles.
This means that the period has to be the same for every PWM generated from one
FLEXIO block, but this way we can get 16-bit resolution for the PWM signals.
For a typical IMX9 HW there are 8 timers for each Flex-IO block, which means
that by using this driver one can get 7 PWM outputs from one block.
This driver can be later extended to have configuration options to use all
8 channels per flex-io by either using 8+8 -bit timer (less resolution) or by
using an external trigger from an LPIT.

when declaring the target to be `nuttx`,create an empty allsyms source file for it;
when the target is declared as something else,the link behavior of the `nuttx` target is cloned
and added to actually generate the allsyms file.
finally use allsyms_nuttx to overwrite the already generated nuttx
and regenerate binary outputs
