New Revision: 25988
   Changeset: http://svn.mythtv.org/trac/changeset/25988

Log:

A couple more streaming DVD/BD optimizations.

1) In mythfile_open, stat the file being opened to verify
   that it is not a directory.  The DVD code likes to
   test whether the pathname supplied is a directory or
   an image or a file, and this helps shorten that test.
   We realy shouldn't be allowing code to open() a
   directory anyway.

2) Work around another SEEK_END usage in the BD code.
   This was used in combination with tell() when reading in
   a lot of the files in order to find out the file size.
   We can use our stat() which is much quicker and won't
   flush the readahead buffer in our RingBuffer.
