* benchmark/bm_io_nonblock_noex2.rb: new benchmark based
on bm_io_nonblock_noex.rb
* io.c (io_read_nonblock): move documentation to prelude.rb
(io_write_nonblock): ditto
(Init_io): private, internal methods for prelude.rb use only
* prelude.rb (IO#read_nonblock): wrapper + documentation
(IO#write_nonblock): ditto
[ruby-core:71439] [Feature #11339]
rb_scan_args and hash lookups for kwargs in the C API are clumsy and
slow. Instead of improving the C API for performance, use Ruby
instead :)
Implement IO#read_nonblock and IO#write_nonblock in prelude.rb
to avoid argument parsing via rb_scan_args and hash lookups.
This speeds up IO#write_nonblock and IO#read_nonblock benchmarks
in both cases, including the original non-idiomatic case where
the `exception: false' hash is pre-allocated to avoid GC pressure.
Now, writing the kwargs in natural, idiomatic Ruby is fastest.
I've added the noex2 benchmark to show this.

path field into rb_iseq_t. The field contains a string representing
a path to corresponding source file. or nil when the iseq is created
from -e, stdin, eval, etc. This field is used for require_relative.
[ruby-dev:40004]
* load.c (rb_f_require_relative): add C implementation of
require_relative.
* prelude.rb (require_relative): get rid of Ruby implementation of
require_relative.

* thread_win32.ci, thread_win32.h, thread_pthread.ci, thread_pthread.h:
prepare native_cond_*() which are based on pthread_cond_*() spec.
* prelude.rb: fix Mutex#synchronize method.
* vm_core.h, include/ruby/intern.h: change unblock function interface
(to pass some user data).
* file.c, process.c: ditto.
* benchmark/bm_vm2_mutex.rb: add a benchmark for mutex.
* benchmark/bm_vm3_thread_mutex.rb: add a benchmark for mutex
with contension.
* benchmark/run.rb: fix to remove ENV['RUBYLIB'] for matzruby.
* test/ruby/test_thread.rb: add a test.
* common.mk: fix benchmark options.

is different from 1.8's. Thread.exclusive only does
synchronize with VM global mutex.
