If the associated clock is either CLOCK_REALTIME or
CLOCK_REALTIME_ALARM, the timer is absolute
(TFD_TIMER_ABSTIME), and the flag TFD_TIMER_CANCEL_ON_SET
was specified when calling timerfd_settime(), then read(2)
fails with the error ECANCELED if the real-time clock
undergoes a discontinuous change. (This allows the
reading application to discover such discontinuous changes
to the clock.)
examples code:
{
int nevents = epoll_wait(epollfd, events, N_ANDROID_TIMERFDS, -1);
if (nevents < 0) {
return nevents;
}
int result = 0;
for (int i = 0; i < nevents; i++) {
uint32_t alarm_idx = events[i].data.u32;
uint64_t unused;
ssize_t err = read(fds[alarm_idx], &unused, sizeof(unused));
if (err < 0 && errno != EAGAIN) {
if (errno == ECANCELED) {
//get time changed
} else {
return err;
}
} else {
//....
}
}
}

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

use the dynamic library .so of the binding compilation environment,
and then modify the dynamic loader of elf at runtime to run sim elf across system versions
1.add post-build for sim build
2.collect dynamic .so and dynamic interpreter
3.add execution script for the entire package sim elf
change text-segment to 0x50000000
because patchelf will modify the .dynamic section in elf,
the upward alignment of elf will be less than 0x3fffffff,
which will cause asan shadow memory overlap error

Reason: xtensa svcall only have level-1 interrupt level.
Sush do not generate interrupt when up_irq_save.
Software int can generate interrupt when up_irq_save.

## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build
They can be used completely independently, so they should'n be coupled.
For example, a sensored motor controller in speed control mode doesn't need an angle estimator.

The packed-attribute on the tcb_info_s type was misplaced, which caused
incompatible memory layout between host and target. According to
current GCC documentation:
> You may specify type attributes in an enum, struct or union type
> declaration or definition by placing them immediately after the struct,
> union or enum keyword. You can also place them just past the closing
> curly brace of the definition, but this is less preferred because
> logically the type should be fully defined at the closing brace.
I also added jlink-nuttx.so to the .gitignore list and updated nxstyle
to ignore the camel case function names required by JLinkGDBServer.

1. remove the unnecessary interfaces tcp_close_monitor()
socket flags(s_flags) is a global state for net connection
remove the incorrect update for stop monitor
2. do not start the tcp monitor from duplicated psock
the tcp monitor has already registered in connect callback
------------------------------------------------------------
This patch also fix the telnet issue reported by:
https://github.com/apache/incubator-nuttx/pull/5434#issuecomment-1035600651
the orignal session fd is closed after dup, the connect state
has incorrectly migrated to close:
drivers/net/telnet.c:
977 static int telnet_session(FAR struct telnet_session_s *session)
...
1031 ret = psock_dup2(psock, &priv->td_psock);
...
1082 nx_close(session->ts_sd);
