GetVersionEx reports 6.2.9200 on Windows 8.1 and later unless the manifest of the executable declares them as supported, and ruby.manifest does not. RtlGetVersion is not affected by the manifest.

A missing variable turned the lower bound into 0, which the existing assertion already covers.

GetSystemInfo() reports the logical processors of the current processor group only, so Etc.nprocessors returned at most 64 on Windows machines with more than 64 logical processors. GetActiveProcessorCount(ALL_PROCESSOR_GROUPS) counts every group. It is looked up at runtime because mingw-w64 declares it only for _WIN32_WINNT >= 0x0601 while the mingw build targets 0x0600.

* Added `Ractor::Port`
* `Ractor::Port#receive` (support multi-threads)
* `Rcator::Port#close`
* `Ractor::Port#closed?`
* Added some methods
* `Ractor#join`
* `Ractor#value`
* `Ractor#monitor`
* `Ractor#unmonitor`
* Removed some methods
* `Ractor#take`
* `Ractor.yield`
* Change the spec
* `Racotr.select`
You can wait for multiple sequences of messages with `Ractor::Port`.
```ruby
ports = 3.times.map{ Ractor::Port.new }
ports.map.with_index do |port, ri|
Ractor.new port,ri do |port, ri|
3.times{|i| port << "r#{ri}-#{i}"}
end
end
p ports.each{|port| pp 3.times.map{port.receive}}
```
In this example, we use 3 ports, and 3 Ractors send messages to them respectively.
We can receive a series of messages from each port.
You can use `Ractor#value` to get the last value of a Ractor's block:
```ruby
result = Ractor.new do
heavy_task()
end.value
```
You can wait for the termination of a Ractor with `Ractor#join` like this:
```ruby
Ractor.new do
some_task()
end.join
```
`#value` and `#join` are similar to `Thread#value` and `Thread#join`.
To implement `#join`, `Ractor#monitor` (and `Ractor#unmonitor`) is introduced.
This commit changes `Ractor.select()` method.
It now only accepts ports or Ractors, and returns when a port receives a message or a Ractor terminates.
We removes `Ractor.yield` and `Ractor#take` because:
* `Ractor::Port` supports most of similar use cases in a simpler manner.
* Removing them significantly simplifies the code.
We also change the internal thread scheduler code (thread_pthread.c):
* During barrier synchronization, we keep the `ractor_sched` lock to avoid deadlocks.
This lock is released by `rb_ractor_sched_barrier_end()`
which is called at the end of operations that require the barrier.
* fix potential deadlock issues by checking interrupts just before setting UBF.

When relative load paths option is enabled, the prefix is determined
at the runtime. The only way to get it outside libruby is to use
rbconfig.rb.

* test/etc/test_etc.rb: Etc.getgrnam would not return the first entry in the order of Etc.group for duplicated group names.

When you change this to true, you may need to add more tests.

* test/etc/test_etc.rb (test_getgrgid, test_getgrnam): relax
comparisons. getgrent() does not return mem properly in some
circumstances (possibly, involved in Open Directory on OSX).

define test cases only if corresponding constants are available.

* test/etc/test_etc.rb (TestEtc#test_getgrgid): fix for non unique GID.
No unixen systems guarantee that GID is unique. Etc.getgrgid would
not return the first entry in the order of Etc.group for shared GID.
