* Tiny sprintf implementation
* Tiny sprintf/vsprintf implementation
* Due to security reasons (buffer overflow) YOU SHOULD CONSIDER USING (V)SNPRINTF INSTEAD!
* \param buffer A pointer to the buffer where to store the formatted string. MUST be big enough to store the output!
* \param format A string that specifies the format of the output
* \param va A value identifying a variable arguments list
* \return The number of characters that are WRITTEN into the buffer, not counting the terminating null character
