7462b199bb signal: SIGCONT can be caught
pass ltp sigaction case 19-5.c, 23-5,c and 28-5.c.
When SIGCONT is dispatched, resume all members of the task group.
So there is nothing do in default action.

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.

d87f350831 arch, boards, drivers, include, sched, wireless: Change spinlock APIs.
Summary:
- This commit changes spinlock APIs (spin_lock_irqsave/spin_unlock_irqrestore)
- In the previous implementation, the global spinlock (i.e. g_irq_spin) was used.
- This commit allows to use caller specific spinlock but also supports to use
  g_irq_spin for backword compatibility (In this case, NULL must be specified)

Impact:
- None

Testing:
- Tested with the following configurations
- spresnse:wifi, spresense:wifi_smp
- esp32-devkitc:smp (QEMU), sabre6-quad:smp (QEMU)
- maxi-bit:smp (QEMU), sim:smp
- stm32f4discovery:wifi

a7265d71c6 This commit adds support for default signal actions for SIGSTOP, SIGSTP, and SIGCONT.
Squashed commit of the following:

    Add procfs support to show stopped tasks.  Add nxsig_action() to solve a chicken and egg problem:  We needed to use sigaction to set default actions, but sigaction() would refuse to set actions if the default actions could not be caught or ignored.

    sched/signal:  Add configuration option to selectively enabled/disable default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT.  Fix some compilation issues.

    sched/sched:  Okay.. I figured out a way to handle state changes that may occur while they were stopped. If a task/thread was already blocked when SIGSTOP/SIGSTP was received, it will restart in the running state.  I will appear that to the task/thread that the blocked condition was interrupt by a signal and returns the EINTR error.

    sched/group and sched/sched:  Finish framework for continue/resume logic.

c0d234a474 Squashed commit of the following:
drivers/serial/Kconfig:  It is no longer necessary to restrict Ctrl-C handling to the FLAT build

    sched/signal:  Add a new configuration option to select signal default actions, separate handling of signal default actions from both task startup logic and from the serial TTY Ctrl-C logic.  Add a signal set in the group structure to keep track of what signals have been set to the default action.  In dispatching signals in PROTECTED or KERNEL mode, use this signal set to determine if the default signal handler is attached and dispatch the signal in kernel mode for the default actions.
