gst_buffer_take_memory -> gst_buffer_insert_memory because insert is what the method does. Make all methods deal with ranges so that we can replace, merge, remove and map a certain subset of the memory in a buffer. With the new methods we can make some code nicer and reuse more code. Being able to deal with a subset of the buffer memory allows us to optimize more cases later (most notably RTP headers and payload that could be in different memory objects). Make some more convenient macros that call the more generic range methods.
