Using any of these functions will cause a tvbuff_t to leak:
tvb_new_octet_aligned
tvb_set_child_real_data_tvbuff
tvb_new_child_real_data
tvb_child_uncompress

The usage_count of the parent tvbuff_t is increased for each child tvbuff_t,
but is not decreased for child tvbuff_t's when tvb_free_chain() is called. 
This causes the parent tvbuff_t to leak.
