* gc.c (rb_gcdebug_print_obj_condition): add the function for debug.
This function shows some conditions of given object (e.g.,
marked, in heap, swept).
* gc.c (rb_gcdebug_sentinel): add the function for debug.
This function allow check to inadvertently free up an object.

* array.c (rb_ary_shared_with_p): fix cache validity check.
If #pop or #shift has been called against $: or $", the array will
be still shared with the snapshot. We check array length for cache
validity.
[ruby-core:49518] [Bug #7383]
* test/ruby/test_require.rb
(TestRequire#test_require_with_array_pop,
TestRequire#test_require_with_array_shift): add tests for above.

explicit rules for same target, but not merges exlicit rules and
implicit rules -- always explict rules win. So, need to add an
explist rule for probes.h.

VM_COLLECT_USAGE_DETAILS is 1. [Bug #7370]

"vm usage information is always collected, so uncomment the
functions." causes performance impact. [Bug #7370]
Off course this revert disables related probes.

* test/ruby/test_string.rb (TestString#test_index): Add some
corner cases to tests for String#index, which might fail if ruby
directly used a buggy memmem(3) implementation.

* ext/io/wait/wait.c (io_wait_writable): this is easier to use than
IO.select for a single IO object and is immune to the
limitations/innefficiency of select() on platforms where poll/ppoll
is available. patched by Eric Wong. [Feature #4646]

have size at least number of its elements, marshal readahead will
read the certain readable length and buffer when it needs more bytes.
marshal readahead prevents many calls to IO#getbyte and IO#read,
then it enables performace improvement.
