mov: Fix overflow and error handling in read_tfra().
Under abnormal conditions the item_count may exceed the max allocation size on 32-bit systems, this causes the allocated size to overflow and become too small for the given count. Additionally, if av_reallocp() fails its allocation, the fragment_index_count is not correctly decremented. Ensuring further havoc may be wrought, the error code for read_tfra() is not checked upon return. Found-by: Paul Mehta <paul@paulmehta.com> positive return code and use of _array functions by commiter Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
