Imports Ruby's port to NativeClient (a.k.a NaCl).

Patch by Google Inc. [ruby-core:45073].

* configure.in (RUBY_NACL): New M4 func to configure variables for
  NaCl.
  (RUBY_NACL_CHECK_PEPPER_TYPES): New M4 func to check the old names
  of Pepper interface types.
  (BTESTRUBY): New variable to specify which ruby should be run on
  "make btest". NaCl can run the built binary by sel_ldr, but it need
  rbconfig.rb. So this variable is distinguished from $MINIRUBY.
  
* thread_pthread.c: Disabled some features on NaCl.

* io.c: ditto.

* process.c: ditto.

* signal.c: ditto.

* file.c: ditto.

* missing/flock.c: ditto.

* nacl/pepper_main.c: An example implementation of Pepper application
  that embeds Ruby.

* nacl/example.html: An example of web page that uses the Pepper
  application.

* nacl/nacl-config.rb: Detects variants of NaCl SDK.

* nacl/GNUmakefile.in: Makefile template for NaCl specific build
  process.

* nacl/package.rb: script for packaging a NaCl-Ruby embedding
  application. 

* nacl/reate_nmf.rb: Wrapper script of create_nmf.py

* dln.c (dln_load): Added a hack to call on NaCl.

* util.c (ruby_getcwd): Path to the current directort is not available
  on NaCl.

+= Native Client port of Ruby
+
+= How to build
+== Prerequisites
+You need to install the following things before building NaCl port of Ruby.
+* Ruby 1.9.3 or later
+* Python 2.6 or later
+* NativeClient SDK pepper 18 or later
+* GNU make
+
+== Steps
+(1) Extract all files from the tarball:
+ $ tar xzf ruby-X.Y.Z.tar.gz
+(2) Set NACL_SDK_ROOT environment vairanble to the path to the Native Client SDK you installed:
+ $ export NACL_SDK_ROOT=/home/yugui/src/nacl_sdk/pepper_16
+(3) Configure
+ $ ./configure --prefix=/tmp/nacl-ruby --host=x86_64-nacl --with-baseruby=/path/to/ruby-1.9.3
+(4) Make
+ $ make
+ $ make package
+
+Now you have ruby.nexe. You can run it by sel_ldr in NaCl SDK.
+
+"make package" installs "pepper-ruby.nexe", an example Pepper application that
+embeds Ruby", and libraries to $prefix. You can run it by the following steps:
+(5) Publish the $prefix directory on a web server
+(6) Visit the example.html on the web server by a browser that implements Pepper 18 or later.
+ -- e.g., Chrome 18 implements Pepper 18, Chrome 19 implements Pepper 19, ...
