mkv: Added reconstruct function to EbmlParser

The two overloads of EbmlParser::reconstruct has been added due to the
fact that there are _a lot_ of places in the code following the below:

    delete ep;
    ep = new EbmlParser (a, b, c, b);

The above will, unless the compiler feels cocky and optimizes it to what
is included in this patch. First free the memory used, and then allocate
new memory for a new EbmlParser.

Instead of doing what is effectively a reallocation, this patch
introduces EbmlParser::reconstruct which will reconstruct the object
in-place (without actually having to reallocate the underlying storage).
