* configure.in (isinf, isnan): isinf() and isnan() are macros on
  DragonFly which cannot be found by AC_REPLACE_FUNCS().  This
  workaround enforces the fact that they exist on DragonFly.

* vm_core.h (rb_call_info_t::refinements), compile.c (new_callinfo),
  vm_insnhelper.c (vm_search_method): revert r37616 because it's too
  slow.  [ruby-dev:46477]

Fix dtrace commit r37631, it is [Feature #2565]

* configure.in: disable dtrace because it doesn't work on FreeBSD.

* common.mk (.d.h): moved from Makefile.in and use BASERUBY.

* tool/gen_dummy_probes.rb: reimplemented with ruby because sed is not
  available on Windows Microsoft VC++ environment.
