empty first.

str and len by src.
* gc.c (gc_mark_children): mark src field of regexp.
(obj_free): don't free str field.
* re.c (REG_BUSY): removed.
(rb_reg_initialize): prohibit re-initialize regexp.
(rb_reg_search): use usecnt to prevent freeing regexp currently
using. this prevents SEGV by:
r = /\A((a.)*(a.)*)*b/
r =~ "ab" + "\xc2\xa1".force_encoding("euc-jp")
t = Thread.new { r =~ "ab"*8 + "\xc2\xa1".force_encoding("utf-8")}

* eval.c (Init_eval), gc.c (Init_GC), proc.c (Init_Proc): freeze
preallocated special exceptions.
* eval.c (rb_longjmp): duplicate the thrown exception to set backtrace
if it was frozen.
* gc.c (rb_memerror): raise nomem_error without backtrace if failed to
make backtrace.

This option enables to calculate exact size of current
allocated size by malloc(). You can access these information
with GC.malloc_allocated_size and GC.malloc_allocations.
This option consume additional memory as a header of each memory
object. This option also helps to find out xmalloc()/xfree()
consistency. If you get trouble with this option, some extension
using "free()" instead of "xfree()".
This options is disabled by default.

succeeds. failed malloc size can be huge. it may increase
malloc_limit too big which cause less GC and memory full.
(ruby_vm_xrealloc): ditto.
(rb_objspace): make params.limit and params.increase size_t.

determining heaps_inc from heaps_used, not objects_delta.
(struct rb_objspace): delta removed. change increment, length and
used to long for LP64.
(objects_delta): removed.
(allocate_heaps): add next_heaps_length argument.
(init_heap): renamed from add_heap.
(garbage_collect): use heaps_increment in dont_gc.

(Init_BareVM): per-VM object space support, which is disabled now.
* gc.c (rb_objspace_alloc), vm.c (Init_BareVM): should not use ruby
malloc here.
* gc.c (garbage_collect, etc): performance improvement by passing the
reference instead of refering the global variable in each functions.

reduce malloc() call.
* gc.c (HEAP_SIZE): use smaller heap segment (2K) for more chance
to be freed. based on patch from authorNari <authornari at gmail.com>.
* gc.c (rb_newobj_from_heap): eventually allocate heap segments.

position may shink under the intialized position. [ruby-core:16436]

__builtin_setjmp, _setjmp over setjmp and sigsetjmp.
[ruby-core:16023], [ruby-core:16086]
* configure.in (--with-setjmp-type): new option to override the
default rule in the above.
* eval_intern.h (ruby_setjmp, ruby_longjmp), gc.c (rb_setjmp),
vm_core.h (rb_jmpbuf_t): use RUBY_SETJMP, RUBY_LONGJMP and
RUBY_JMP_BUF.

* eval.c (rb_longjmp): clear all raised flags.
* eval.c (stack_check): leave clearing flag to rb_longjmp.
* gc.c (rb_memerror): use thread raised flag instead of static flag.
