        src/lib/libc/stdio: snprintf.c vsnprintf.c

Log Message:
Fix two bugs:

1. snprintf(foo, 0. "XXX") is guaranteed not to write in foo by the
   standard (ISO/IEC 9899 7.19.6.5) but our implementation handles this
   as if the buffer has a size of (size_t)-1.

2. snprintf(NULL, 0, "XXX") leaks memory since cantwrite() allocates
   memory if _bf._base == NULL, and this buffer is never freed
   (PR 16483).
