Vignesh Venkatasubramanian e369bed319 Support user ownership of files in MkvWriter
Overloading MkvWriter's constructor so that it can wrap a user owned
FILE pointer. Doing this so that applications which handle the file opening
and closing by themselves don't have to have their own implementation of the
IMkvWriter interface.
