172b209f2d sched/assert: Re-implement assert() into user space
_assert is a kernel procedure, entered via system call to make the core
dump in privileged mode.

Running exit() from this context is not OK as it runs the registered
exit functions and flushes streams, which must not be done
from privileged mode as it is a security hole.

Thus, implement assert() into user space (again) and remove the exit()
call from the kernel procedure.

- Access stream list via tg_info in kernel
- Access stream list via TLS in user space

       printf("str is %s\n",p);
  output:num is 1249835483136.000000
         str is lala

but if the input number is much big;
like:
  code:const char *s2= "0x999999p100";
       num=strtof(s2,&p);
       printf("num is %f\n",num);

  corrent : num is 12760587998944832242938906880669384704.000000
  real:     num is 12760587998944800000000000000000000000.000000

expected output : Hello, World!! 2.40992e-181:f64
but real output : Hello, World!! 2.40992e-B1:f64
the reason: we want printf "18", but the flag of character is 'B'

d3ffeb40a7 libc/machine/xtensa: make longjmp safe against context switch
In order to turn longjmp context-switch safe, it's necessary
to disable interrupts before modifying windowbase and windowstart.
Otherwise, after a context switch, windowstart and windowbase
would be different, leading to a wrongly set windowstart bit due to
longjmp writing it based on the windowbase before the context switch.
This corrupts the registers at the next window overflow reaching
that wrongly set bit.

*Background:*
This PR is related to an issue first observed on ESP-IDF
https://github.com/espressif/esp-idf/issues/5229 and it was, then,
checked on NuttX using a test application.

*The test application:*
To check if the problem affects ESP32, ESP32-S2 and ESP32-S3 on
NuttX, it was created an application based on:
https://en.cppreference.com/w/c/program/longjmp

The application creates 16 tasks (`#define NUMBER_OF_TASKS  16`)
that implements the following daemon:

```
static int setjmp_longjmp_daemon(int argc, char *argv[])
{
  for (int i = 0; i < NUMBER_OF_TASKS * 2; i++)
    {
      jmp_buf env;

      volatile int count = 0;
      if (setjmp(env) != UINT16_MAX)
        {
          foo(&env, ++count);
        }
    }

  sem_post(&g_sem);

  return EXIT_SUCCESS;
}
```

The main function also initializes a semaphore to avoid application
exiting before tasks return successfully:

```
  sem_init(&g_sem, 0, -NUMBER_OF_TASKS);
```

Finally, the round-robin interval was lowered to 1ms to raise the
chances of the longjmp being interrupted by a context switch
(`CONFIG_RR_INTERVAL=1).

This setup was able to reproduce the problem prior to this patch
being applied.

db4840564d dns: Reduce the dns_lock granularity
When a7 curl calls dns_query via usrsock, it will wait a usrsock
response with the dns lock held. If a7 rptun recv a dns_addnameserver
event from another core at this time, rptun waits the lock held by
curl in callback. Then curl will never get its usrsock response with
rptun blocked, so the deadlock occurs.

This change will break lock when do usrsock request.
