and ConditionalVariables to thread_tools.c. In other wowrds,
such classes are built-in.
[Feature #8919]
At first, I planned to embed only a Queue class.
However, rubygems requires 'thread.rb' (rubygems are
required at first, when launch MRI without --disable-gems).
So most of people require 'thread.rb' as an embedded library.
Now, ext/thread/thread.c is empty, only for a dummy for
compatibility.
* thread.c: move a definition of Mutex class to thread_tools.c.
And define Mutex class under Thread (so now Mutex is Thread::Mutex).
Because other thread related classes are also defined under Thread.
We remain ::Mutex as Thread::Mutex. Only an inspect result is changed.
* common.mk: add dependency from thread.o to thraed_tools.c.

Shutting down the timer thread now always closes pipes to free FDs.
In fact, we close the write ends of the pipes is done in the main
RubyVM to signal the timer thread shutdown.
To effectively close pipes, we implement userspace locks via
atomics to force the pipe closing thread to wait on any signal
handlers which may be waking up.
While we're at it, improve robustness during resource exhaustion and
allow it to limp along non-fatally if restarting a timer thread
fails.
This reverts r51268

All contents of previous rb_iseq_t is in rb_iseq_t::body.
Remove rb_iseq_t::self because rb_iseq_t is an object.
RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq.
So RubyVM::ISeq.of(something) method returns different wrapper
objects but they point the same T_IMEMO/iseq object.
This patch is big, but most of difference is replacement of
iseq->xxx to iseq->body->xxx.
(previous) rb_iseq_t::compile_data is also located to
rb_iseq_t::compile_data.
It was moved from rb_iseq_body::compile_data.
Now rb_iseq_t has empty two pointers.
I will split rb_iseq_body data into static data and dynamic data.
* compile.c: rename some functions/macros.
