Share `increment' information with heaps.
* gc.c: change ratio of heap_pages_free_min_page
to 0.80.
This change means slow down page freeing speed.

Tomb heap is where zombie objects and ghost (freed slot) lived in.
Separate from other heaps (now there is only eden heap) at sweeping
helps freeing pages more efficiently.
Before this patch, even if there is an empty page at former phase
of sweeping, we can't free it.
Algorithm:
(1) Sweeping all pages in a heap and move empty pages from the
heap to tomb_heap.
(2) Check all exsisting pages and free a page
if all slots of this page are empty and
there is enough empty slots (checking by swept_num)
To introduce this pach, there are several tuning of GC parameters.

Now, objects are managed by page. And a set of pages is called heap.
This commit supports multiple heaps in the object space.
* Functions heap_* and rb_heap_t manages heap data structure.
* Functions heap_page_* and struct heap_page manage page data
strcuture.
* Functions heap_pagse_* and struct rb_objspace_t::heap_pages
maintains all pages.
For example, pagaes are allocated from the heap_pages.
See https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/GC_design
and https://bugs.ruby-lang.org/attachments/4015/data-heap_structure_with_multiple_heaps.png
for more deitals.
Now, there is only one heap called `eden', which is a space for all
new generated objects.

This fix a problem caused by %p in C generates variable length
address.

There is a bug that T_ZOMBIE objects are not collected.
Because there is a pass to miss finalizer postponed job
with multi-threading. This patch solve this issue.
* vm_trace.c (rb_postponed_job_register_one): set
RUBY_VM_SET_POSTPONED_JOB_INTERRUPT(th) if another same job
is registered.
There is a possibility to remain a postponed job without
interrupt flag.
* vm_trace.c (rb_postponed_job_register_one): check interrupt
carefully.
* vm_trace.c (rb_postponed_job_register_one): use additional space
to avoid buffer full.
* gc.c (gc_finalize_deferred_register): check failure.
* thread.c (rb_threadptr_execute_interrupts): check
`postponed_job_interrupt' immediately. There is a possibility
to miss this flag.

bail out early if not.

* encoding.c (load_encoding): should preserve outer errinfo, so that
expected exception may not be lost. [ruby-core:57949] [Bug #9038]

* io.c (rb_io_reopen): create a new, temporary FD via rb_sysopen and
call rb_cloexec_dup2 on it to atomically replace the file fptr->fd
points to. This leaves no possible window where fptr->fd is invalid
to userspace (even for any threads running w/o GVL). based on the
patch by Eric Wong <normalperson@yhbt.net> at [ruby-core:57943].

Only attempt to build extensions for newly-installed gems. This
prevents compilation attempts at gem activation time for gems that
already have extensions built.
Fix crash in the dependency resolver for dependencies that cannot be
resolved.

in rb_objspace_t::heap.
* rename rb_objspace_t::heap::sorted to
rb_objspace_t::heap_sorted_pages

* rename rb_objspace_t::heap::range to
rb_objspace_t::heap_range and rename macros
lomem/himem to heap_lomem/heap_himem.
