* include/ruby/ruby.h: replace snprintf and vsnprintf by

  ruby_snprintf and ruby_vsnprintf. [ruby-dev:40909]

* configure.in: don't check snprintf(3) and vsnprintf(3).

* include/ruby/missing.h: don't delare snprintf and vsnprintf.

* include/ruby/ruby.h: include stdarg.h.

* sprintf.c: include vsnprintf.c

* vsnprintf.c: renamed from missing/vsnprintf.c.

* vsnprintf.c: remove useless ifdefs.

* win32/mkexports.rb: use ruby_snprintf and ruby_vsnprintf.

- *      snprintf should be the only externally visible item.
