BSD version has different prototype.

* util.h: use qsort_r() as ruby_qsort() if it is GNU version.

* util.c: define ruby_qsort() if needed.

yugui 76bc2d1ed7 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.

usa f9e9eee677 * util.c, include/ruby/util.h (ruby_add_suffix): remove the function. 
[Bug #5153] [ruby-core:38736]

* io.c (argf_next_argv): remove the call of above function.

* ext/-test-/add_suffix, test/-ext-/test_add_suffix.rb: remove the test
  extension module because this is only for testsing ruby_add_suffix().

* LEGAL: remove the mention about a part of util.c, because now we
  removed the part.

* io.c (argf_next_argv): now the new filename is not guranteed to
  use, so should check the return value of rename(2).

* test/ruby/test_argf.rb (TestArgf#test_inplace_rename_impossible):
  now we expect same result with other platforms on no_safe_rename
  platforms (=Windows).
