717bb04cb7 Increase the number of real time signals. Two is not enough.
Refer to issue #8867 for details and rational.

Convert sigset_t to an array type so that more than 32 signals can be supported.

Why not use a uin64_t?
- Using a uin32_t is more flexible if we decide to increase the number of signals beyound 64.
- 64-bit accesses are not atomic, at least not on 32-bit ARMv7-M and similar
- Keeping the base type as uint32_t does not introduce additional overhead due to padding to achieve 64-bit alignment of uin64_t
- Some architectures still supported by NuttX do not support uin64_t
  types,

Increased the number of signals to 64. This matches Linux. This will support all xsignals defined by Linux and also 32 real time signals (also like Linux).

This is is a work in progress; a draft PR that you are encouraged to comment on.

07039b8a36 lib_abort.c: Change call to userspace exit() into syscall _exit()
The POSIX standard dictates that during abnormal termination the functions
registered by atexit() are _not_ called, also flushing the streams is
optional. So in this case, it is perfectly legal / better to call the
kernel system call _exit() instead.

This fixes regression issues caused by removal exit() from the kernel.

e9ef70e24b sched/assert: Call abort() instead of exit() in assert
POSIX dictates that assert() terminates via abort(), even though in NuttX
abort() just calls exit(EXIT_FAILURE) it is better to use the correct
API here, if at some point a proper implementation for abort() is made.

Also, as the kernel must not use abort() which is a userspace API, direct
the exit to PANIC() if for some reason _assert() returns (it should not
but trap it here just in case).

df1d7dd480 libc/exit: Purge calls to userspace API exit() from kernel
Remove calls to the userspace API exit() from the kernel. The problem
with doing such calls is that the exit functions are called with kernel
mode privileges which is a big security no-no.

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.
