Add public GC_set_handle_fork to control forked child handling support
* include/gc.h (GC_set_handle_fork): New API function.
* misc.c (GC_set_handle_fork): Likewise.
* include/private/gc_priv.h (GC_handle_fork): New internal variable
declaration (only if CAN_HANDLE_FORK).
* misc.c (GC_handle_fork): New internal variable (defined only if
CAN_HANDLE_FORK); initialize to TRUE if HANDLE_FORK.
* include/private/gcconfig.h (HANDLE_FORK): Replace with
CAN_HANDLE_FORK.
* pthread_support.c (HANDLE_FORK): Likewise.
* win32_threads.c (HANDLE_FORK): Likewise.
* include/private/gcconfig.h (CAN_HANDLE_FORK): Always define macro if
HANDLE_FORK.
* pthread_support.c (GC_thr_init): Replace HANDLE_FORK with
CAN_HANDLE_FORK; call pthread_atfork only if GC_handle_fork; update
the comment.
* win32_threads.c (GC_thr_init): Likewise.
* tests/test.c (NO_TEST_HANDLE_FORK): Define new macro if fork
handling is not supported (or is a no-op) on the target.
* tests/test.c (INIT_FORK_SUPPORT): New macro (invoke
GC_set_handle_fork unless NO_TEST_HANDLE_FORK).
* tests/test.c (GC_OPT_INIT): New macro (defined to GC_INIT or empty).
* tests/test.c (GC_COND_INIT): Use INIT_FORK_SUPPORT and GC_OPT_INIT.
* tests/test.c (run_one_test): Test NO_TEST_HANDLE_FORK (instead of
target-specific macros).
* win32_threads.c (GC_remove_all_threads_but_me, GC_fork_prepare_proc,
GC_fork_parent_proc, GC_fork_child_proc): Do not test GC_PTHREADS.
* configure.ac (HANDLE_FORK, NO_HANDLE_FORK): Update message.
