annotate libinterp/corefcn/sighandlers.cc @ 22051:6db928d06b07

move signal functions into octave namespace * sighandlers.h, sighandlers.cc: Move all functions and variables into the octave namespace. Change all uses. (base_interrupt_manager, posix_interrupt_manager, interrupt_manager): New classes. (w32_interrupt_manager): Derive from base_interrupt_manager. Limit Windows-specific code to this class alone. (interrupt_manager::create_instance): Create w32_interrupt_manager instance on Windows systems.
