Working CTRL-C handling implementation for Win32. * libgui/src/thread-manager.cc (sighandlers.h): New include. (windows_thread_manager::interrupt): Call w32_raise_sigint instead of ::raise. * libinterp/corefcn/sighandlers.h (w32_raise_sigint): New declatation. * libinterp/cirefcn/sighandlers.cc (user_abort): Forward declare. (class w32_interrupt_manager): New singleton helper class. (w32_raise_sigint): New function. (user_abort): Call w32_interrupt_manager::octave_jump_to_enclosing_context instead of octave_jump_to_enclosing_context on Win32 platform. (sigint_handler): Call w32_interrupt_manager::user_abort instead of user_abort on Win32 platform. (octave_catch_interrupts, octave_ignore_interrupts, octave_set_interrupt_handler): Call w32_interrupt_manager::init on Win32 platform. * liboctave/util/oct-rl-edit.c (octave_rl_initialize): Set rl_catch_signals to 0 on Win32 platform.
