Remove several race conditions with signal handler (bug #61370).
This patch removes several race conditions between the interpreter and the
Ctrl-C signal handler, as described in more detail in bug #61370.
* libinterp/corefcn/sighandlers.h: Make can_interrupt atomic.
* libinterp/corefcn/sighandlers.cc: Make can_interrupt, signals_caught atomic,
use atomic value read for signals_caught, octave_interrupt_state,
change 1 to true.
* liboctave/util/quit.h: Move octave_interrupt_state and octave_signal_caught
to C++ only code, rewrite octave_quit() function, rewrite OCTAVE_QUIT macro
to use octave_quit_c() function.
* liboctave/util/quit.cc: Make octave_interrupt_state and octave_signal_caught
atomic, add new wrapper function octave_quit_c().
* libinterp/corefcn/interpreter.h: Make octave_initialized atomic.
* libinterp/corefcn/interpreter.cc: Make octave_initialized atomic,
change 0 to false.
* liboctave/util/action-container.h: New namespace "util", make m_val atomic.
* liboctave/util/oct-atomic.c: Reorder preprocessor if-elif-else ladder.
* liboctave/util/cmd-edit.cc: Change 0 to false.
