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.
