0e782661d6 cbs_h264: Fix overflow in shifts 
The type of the result of a shift operation is unaffected by the type of
the right operand, so some existing code overflows with undefined behaviour
when the element length is 32.  Add a helper macro to calculate the maximum
value correctly and then use it everywhere this pattern appears.

ce5870a3a8 cbs: Refcount all the things! 
This makes it easier for users of the CBS API to get alloc/free right -
all subelements use the buffer API so that it's clear how to free them.
It also allows eliding some redundant copies: the packet -> fragment copy
disappears after this change if the input packet is refcounted, and more
codec-specific cases are now possible (but not included in this patch).
