merges r20909 and r20910 from trunk into ruby_1_9_1.
configure.in (mingw): no longer uses snprintf and vsnprintf of msvcrt.
win32/win32.c (rb_w32_vsnprintf, rb_w32_snprintf): removed.
win32/Makefile.sub (config.h): vsnprintf exists in VC7 or later.
win32/mkexports.rb (Exports#initialize): aliases rb_w32_vsnprintf and rb_w32_snprintf for binary compatibility.
sprintf.c (rb_str_format): uses snprintf instead of sprintf.
numeric.c (flo_to_s, rb_num2long, rb_num2ll): ditto.
