Petteri Aimonen 0648a61668 sigaction: Expand si_user for non-kernel signals
Commit 9244b5a737 added support
for non-standard field si_user that is useful for passing context
pointers to signal handlers.

This commits makes it work for all signals, not just SA_KERNELHAND.
Previously si_user for normal signals was uninitialized garbage.

Gregory Nutt 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.

Gregory Nutt 104a7d4e00 Correct Real Time signal definitions.
There are number problems with the implementation of realtime signals in NuttX as discussed in Issue #8869.  A first step to correcting any of these is to correct the definitions of SIGRTMIN, SIGRTMAX, and RTSIG_SIX.

SIGRTMIN is the first real-time signals.  Real-time signal numbers must not overlap the standard signal numbers.  Before this fix, it was set equal to the first standard signal.  Real-time signals differ from standard signals in that (1) they have no default actions, and (2) real time signal actions are prioritized whereas standard signal actions are processed FIFO.

SIGRTMAX is the last real-time signal.

RTSIG_MAX must be set equal to maximum number of realtime signals reserved for application use

The change corrects the definitons but has not impact at all becasuse none of there definitions are currently used in the OS.  But they will be when prioritized real time signal handling is implemented.

Gregory Nutt 67ec3d7926 Remove CONFIG_CAN_PASS_STRUCT
This commit resolves issue #620:

Remove CONFIG_CAN_PASS_STRUCTS #620

The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    struct mallinfo mallinfo(void);
    #else
    int      mallinfo(FAR struct mallinfo *info);
    #endif

And even leads to violation of a few POSIX interfaces like:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    int  sigqueue(int pid, int signo, union sigval value);
    #else
    int  sigqueue(int pid, int signo, FAR void *sival_ptr);
    #endif

This breaks the 1st INVIOLABLES rule:

Strict POSIX compliance
-----------------------

  o Strict conformance to the portable standard OS interface as defined at
    OpenGroup.org.
  o A deeply embedded system requires some special support.  Special
    support must be minimized.
  o The portable interface must never be compromised only for the sake of
    expediency.
  o Expediency or even improved performance are not justifications for
   violation of the strict POSIX interface

Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: z88dk/z88dk#1132

NOTE:  This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.

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.
