Fixes out of array reads

Memory passed to av_realloc must come from malloc,
calloc or realloc, and not e.g. memalign. realloc(3):

The realloc() function changes the size of the memory block pointed to
by ptr to size bytes. (...) Unless ptr is NULL, it must have been
returned by an earlier call to malloc(), calloc() or realloc().

The issue has been found by debugallocation, a part of google-perftools:
http://code.google.com/p/gperftools/ .

This makes fate pass when using LD_PRELOAD-ed debugallocation.

That field will be deprecated.

I.e. don't do anything on already released frames.

This container does not store timestamps and thus supports CFR only.

There is no point in keeping those two functions separate.

The existing checks are insufficient to detect a pixel format
changes in case of some damaged streams.
