      Add casts to avoid errors due to narrowing · 6d7d5013
      Martin Storsjo authored 
      This fixes building in C++11 mode, which normally errors out
on narrowing hex literals to signed long.

This is similar to what was done in git commit ef308366
(change id I64d19a8a8059c5a96386b1eaac297fd2469515f8), completing
the fix for that category of issues.

      Fix aacDecoder_drcExtractAndMap() · 97a1b814
      Jean-Michel Trivi authored 
      Parse DVB DRC data only when numThreads is below
 MAX_DRC_THREADS. The post-increment is necessary as
 it is used in fill element DRC data section.
This solution parses as many DRC payloads as allowed by
 MAX_DRC_THREADS and skips all remaining DRC elements in the stream.
