sigsegv handler. enlarge value when x86 or x86_64 on Linux.
Linux has very small MINSIGSTKSZ size (2048 bytes) and
our sigsegv routine need 5KiB at least. [Bug #7141]
* internal.h: add declaration of rb_sigaltstack_size().
* vm_core.h: remove ALT_STACK_SIZE definition.
* signal.c (rb_register_sigaltstack): replace ALT_STACK_SIZE with
rb_sigaltstack_size();
* gc.c (Init_heap): ditto.
* vm.c (th_init): ditto.

entry with VM_METHOD_TYPE_REFINED holds only the original method
definition, so ci->me is set to a method entry allocated in the
stack, and it causes SEGV/ILL. In this commit, a method entry
with VM_METHOD_TYPE_REFINED holds the whole original method entry.
Furthermore, rb_thread_mark() is changed to mark cfp->klass to
avoid GC for iclasses created by copy_refinement_iclass().
* vm_method.c (rb_method_entry_make): add a method entry with
VM_METHOD_TYPE_REFINED to the class refined by the refinement if
the target module is a refinement. When a method entry with
VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
the same name is searched in refinements. If such a method is
found, the method is invoked. Otherwise, the original method in
the refined class (rb_method_definition_t::body.orig_me) is
invoked. This change is made to simplify the normal method lookup
and to improve the performance of normal method calls.
* vm_method.c (EXPR1, search_method, rb_method_entry),
vm_eval.c (rb_call0, rb_search_method_entry): do not use
refinements for method lookup.
* vm_insnhelper.c (vm_call_method): search methods in refinements if
ci->me is VM_METHOD_TYPE_REFINED. If the method is called by
super (i.e., ci->call == vm_call_super_method), skip the same
method entry as the current method to avoid infinite call of the
same method.
* class.c (include_modules_at): add a refined method entry for each
method defined in a module included in a refinement.
* class.c (rb_prepend_module): set an empty table to
RCLASS_M_TBL(klass) to add refined method entries, because
refinements should have priority over prepended modules.
* proc.c (mnew): use rb_method_entry_with_refinements() to get
a refined method.
* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
copy_refinement_iclass().
* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.
* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
the test because it should pass successfully.
* test/ruby/test_refinement.rb (test_redefine_refined_method): new
test for the case a refined method is redefined.

* array.c (rb_ary_delete_same_obj): new function for WeakRef.
This deletes same objects as item argument in the array.
* internal.h (rb_ary_delete_same_obj): add a declaration.
* gc.c (wmap_final_func): remove WeakRef object reference from the
array. rb_ary_delete() is not usable because it uses rb_equal() to
compare object references.
* gc.c (wmap_finalize): remove recycled object references from weak
map hash properly. How to get object reference from object id was
wrong. st_delete() doesn't work properly if key and value arguments
are same. The key of obj2wmap is referenced object and the value of
obj2wmap is WeakRef array.
* gc.c (wmap_aset): obj2wmap should contain WeakRef array in the
definition.
* test/test_weakref.rb
(TestWeakRef#test_not_reference_different_object,
TestWeakRef#test_weakref_finalize): add tests for above.

* include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c

ultimate ifdef's to ruby/ruby.h. Gcc hides its builtin alloca()
when compiling with -ansi, and linking thus fails on platforms
that lack their own alloca() implementation in libc, which
include OpenBSD and some ports of NetBSD. We use alloca()
everywhere including from within third party C extentions, so
alloca() must be made globally available. [Bug #7307]
