  1. Fix overflow issues found by fuzzer 

    Fuzzer had caught a number of large malloc and these large malloc were caused
by overflow of AP4_UI32 causing the validation logic to be skipped.

  2. Add boundary checks to Ap4IproAtom 

    Fuzzer caught another large malloc. This is caused by lack of boundary check
resulting in the next atom (children atom) to artificially large "size"
due to the underflow in bytes_available.
