Implement malloc_vsnprintf() (a subset of vsnprintf(3)) as well as several other printing functions based on it, so that formatted printing can be relied upon without concern for inducing a dependency on floating point runtime support. Replace malloc_write() calls with malloc_*printf() where doing so simplifies the code. Add name mangling for library-private symbols in the data and BSS sections. Adjust CONF_HANDLE_*() macros in malloc_conf_init() to expose all opt_* variable use to cpp so that proper mangling occurs.
