c4fc414b09 libc: unistd: lib_getrlimit: use INT_MAX as dummy rlim_max value.

2e5a20612c libc: unistd: lib_getrlimit: return a value for RLIMIT_NOFILE request.
In the Nim language "selectors"(I/O multiplexing) module, the maximum
number of file descriptors is obtained with getrlimit() as follows.

        var fdLim: RLimit
        var res = int(getrlimit(RLIMIT_NOFILE, fdLim))
        if res >= 0:
          res = int(fdLim.rlim_cur) - 1

To be able to use the same implementation as other POSIX-based OS,
getrlimit() should return a value.
(For now, let it return 128.)

409e2f3701 drivers/serial, libc/termios: Implement tcsendbreak
The TERMIOS(3) function tcsendbreak() and the IOCTLs TCSBRK and TCSBRKP
transmit a serial line Break.

Previously NuttX included an extern declaration for tcsendbreak() and
defines for TCSBRK and TCSBRKP but none of these were implemented.
Attempting to build programs that called tcsendbreak() would fail with
a linker error; attempting to use TCSBRK and TCSBRKP would result in an
error at runtime.

This changeset adds the tcsendbreak() function and handling for TCSBRK
and TCSBRKP; tcsendbreak() is implemented in terms of TCSBRK. Both
TCSBRK and TCSBRKP are implemented in terms of the BSD-compatible Break
IOCTLs TIOCSBRK and TIOCCBRK, which must be provided by the lower half
serial driver. Currently, not all lower half serial drivers in NuttX
support these IOCTLs. Those that do implement them may need one or more
Kconfig options to be set, such as `CONFIG_*_U[S]ART_BREAKS` and, on
some architectures, a separate `CONFIG_*_SERIALBRK_BSDCOMPAT`.

* drivers/serial/serial.c
  (uart_tcsendbreak): New function.
  (uart_ioctl): Implement TCSBRK and TCSBRKP.

* libs/libc/termios/lib_tcsendbreak.c
  (): New file.

* libs/libc/termios/Make.defs
  (CSRCS): Add lib_tcsendbreak.c to the build.

Thanks to Xiang Xiao for PR feedback.

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.

965566d2e8 libc/stdio: add total_len back
"The number of characters written if successful or negative value if an error occurred.
If the resulting string gets truncated due to buf_size limit, function returns the total
number of characters (not including the terminating null-byte) which would have been written,
if the limit was not imposed." --- https://en.cppreference.com/w/c/io/vfprintf

fa59db8cea Add Hexadecimal parsing for strtof
solve:
  almost the Hexadecimal string string->float
such as:
  code:float num;
       const char *s= "0x123p32lala";
       char *p;
       num=strtof(s,&p);
       printf("num is %f\n",num);
       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);
       printf("str is %s\n",p);
  corrent : num is 12760587998944832242938906880669384704.000000
  real:     num is 12760587998944800000000000000000000000.000000
it didn't have enough precision
