* stdlib/Makefile (routines): Add quick_exit, at_quick_exit, and
cxa_at_quick_exit. (static-only-routines): Add at_quick_exit. * stdlib/Versions: Export quick_exit and __cxa_at_quick_exit for GLIBC_2.10. * stdlib/quick_exit.c: New file. * stdlib/at_quick_exit.c: New file. * stdlib/cxa_at_quick_exit.c: New file. * stdlib/cxa_atexit.c (__cxa_atexit): Move body to new function. Call it appropriately. (__internal_atexit): New function. (__new_exitfn): Now takes parameter to point to the list to use. * stdlib/cxa_finalize.c: Remove quick_exit handlers, don't call them. * stdlib/exit.c (__run_exit_handlers): New function. Split from... (exit): ...here. Just call __run_exit_handlers appropriately. * stdlib/exit.h: Declare __quick_exit_funcs, __run_exit_handlers, __internal_atexit, __cxa_at_quick_exit. Adjust __new_exitfn. * stdlib/on_exit.c: Adjust call to __new_exitfn. * stdlib/stdlib.h: Declare at_quick_exit and quick_exit.
