st: test packed-to-unpacked transitions during iteration

The st_foreach and st_foreach_check functions support transitioning
from a packed to an unpacked state during iteration.  However, this
functionality did not get exercised by the current test suite until
now.  This should help us prevent breakage when making modifications
to st.

* ext/-test-/st/foreach/extconf.rb: new file
* ext/-test-/st/foreach/foreach.c: ditto
* test/-ext-/st/test_foreach.rb: ditto

Merges a patch form naclports.

* configure.in (RUBY_NACL and others): Supports PNaCl.
* dln.c: replace the old hacky dynamic loading over HTTP with nacl_io.
* file.c: tenatively use access(2) instead of eaccess.
  (rb_file_load_ok): weaken with attribute but not by postprocess.
* io.c (socket.h): now NaCl has socket.h
  (flock): disable here instead of nacl/ioctl.h
* nacl/GNUmakefile.in (CC, LD, NM, AR, AS, RANLIB, OBJDUMP, OBJCOPY):
  respect path to them if they are absolute.
  This helps naclports to build ruby in their source tree.
  (PROGRAM_NMF, .SUFFIXES): support .pnexe for PNaCl.
  (ruby.o, file.o): move the hack to attributes in ruby.c and file.c
* nacl/ioctl.h: removed. move the hack to io.c.
* nacl/nacl-config.rb: support arm, pnacl and others.
* nacl/pepper_main.c: support build in a naclports tree.
* ruby.c (rb_load_file): weaken with attribute but not by postprocess.

The patch is by sbc@google.com and the Native Client Authors.
It is available at:
* https://chromium.googlesource.com/external/naclports.git/+/873ca4910a5f9d4206306aacb4ed79c587c6a5f3/ports/ruby/nacl.patch
