Writing the duration SimpleTag is special: It's size is reserved in advance via an EBML Void element (if seekable) and this reserved space is overwritten when writing the trailer; it does not use put_ebml_string(). The string to write is created via snprintf on a buffer of size 20; this buffer is then written via put_ebml_binary() with a size of 20. EBML strings need not be zero-terminated; if not, they are implicitly terminated by the element's length field. snprintf() always zero-terminates the buffer, i.e. the last byte can be discarded when using an EBML string. This patch does this. The FATE changes are as expected: One byte saved for every track; the only exception is the matroska-qt-mode test: An additional byte is saved because an additional byte could be saved from the enclosing Tags length field.
