This will allow the caller to enumerate child contexts in a generic way
and since the API is recursive, it also allows for deeper nesting (e.g.
AVFormatContext->AVIOContext->URLContext)
This will also allow the new setting/reading API to transparently apply
to children contexts.

These additions might overflow the signed range for large
input values. Converting to unsigned before the addition
rather than after avoids such undefined behaviour. The
result under normal two's complement wraparound remains
unchanged.
