The code assumed that /usr/share/dict/words did not use mixed
case, and it does at least on a few operating systems.

Fixes [Bug #16957]
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
Asynchronous events such as signal trap, finalization timing,
thread switching and so on are managed by "interrupt_flag".
Ruby's threads check this flag periodically and if a thread
does not check this flag, above events doesn't happen.
This checking is CHECK_INTS() (related) macro and it is placed
at some places (laeve instruction and so on). However, at the end
of C methods, C blocks (IMEMO_IFUNC) etc there are no checking
and it can introduce uninterruptible thread.
To modify this situation, we decide to place CHECK_INTS() at
vm_pop_frame(). It increases interrupt checking points.
[Bug #16366]
This patch can introduce unexpected events...
This removes the related tests, and puts the related specs behind
version guards. This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
After 5e86b005c0, I now think ANYARGS is
dangerous and should be extinct. This commit deletes ANYARGS from
rb_rescue / rb_rescue2, which revealed many arity / type mismatches.
After 5e86b005c0, I now think ANYARGS is
dangerous and should be extinct. Let's start from making
rb_block_call_func_t strict, and apply RB_BLOCK_CALL_FUNC_ARGLIST liberally.
For array.c (Array#sort) and enum.c (Enumerable#sort_by),
add comments mentioning that sort.reverse! / sort_by { ... }.reverse!
can/should be used to reverse the result. [ci skip]
Existing doc for Enumerable#include? and member? has some problems.
* `IO.constants` is not commonly used, and only some know
that `SEEK_SET` is actually included in constants.
* `IO.constants` is actually an Array, not the example is not
appropriate for `Enumerable` module.
So in this commit, the old example is replaced with new one.
New example uses integer range, which is much simpler and easier to
understand.

memo.float_value might change inside of hash_sum. In case it
flipped from false to true there, and the calculated sum is Inf,
memo.c might not be initialized at all. This is bad.

* enum.c (enum_tally): new methods Enumerable#tally, which group
and count elements of the collection. [Feature #11076]

Especially over checking argc then calling rb_scan_args just to
raise an ArgumentError.

* include/ruby/ruby.h: de-transient at
`RARRAY_PTR_USE` and `RARRAY_PTR_USE_START`.
Introduce `RARRAY_PTR_USE_TRANSIENT` and
`RARRAY_PTR_USE_START_TRANSIENT` if you don't want to
de-transient an array. Generally, it is difficult
so C-extension writers should not use them.
* array.c: use `RARRAY_PTR_USE_TRANSIENT` if possible.
* hash.c: ditto.
* enum.c (enum_sort_by): remove `rb_ary_transient_heap_evacuate()`
because `RARRAY_PTR_USE` do de-transient.

* transient_heap.c, transient_heap.h: implement TransientHeap (theap).
theap is designed for Ruby's object system. theap is like Eden heap
on generational GC terminology. theap allocation is very fast because
it only needs to bump up pointer and deallocation is also fast because
we don't do anything. However we need to evacuate (Copy GC terminology)
if theap memory is long-lived. Evacuation logic is needed for each type.
See [Bug #14858] for details.
* array.c: Now, theap for T_ARRAY is supported.
ary_heap_alloc() tries to allocate memory area from theap. If this trial
sccesses, this array has theap ptr and RARRAY_TRANSIENT_FLAG is turned on.
We don't need to free theap ptr.
* ruby.h: RARRAY_CONST_PTR() returns malloc'ed memory area. It menas that
if ary is allocated at theap, force evacuation to malloc'ed memory.
It makes programs slow, but very compatible with current code because
theap memory can be evacuated (theap memory will be recycled).
If you want to get transient heap ptr, use RARRAY_CONST_PTR_TRANSIENT()
instead of RARRAY_CONST_PTR(). If you can't understand when evacuation
will occur, use RARRAY_CONST_PTR().

RARRAY_CONST_PTR() can introduce additional overhead in a futre.
