* configure.in (RUBY_SETJMP, RUBY_LONGJMP, RUBY_JMP_BUF): prefers

  __builtin_setjmp, _setjmp over setjmp and sigsetjmp.
  [ruby-core:16023], [ruby-core:16086]

* configure.in (--with-setjmp-type): new option to override the
  default rule in the above.

* eval_intern.h (ruby_setjmp, ruby_longjmp), gc.c (rb_setjmp),
  vm_core.h (rb_jmpbuf_t): use RUBY_SETJMP, RUBY_LONGJMP and
  RUBY_JMP_BUF.
