Wim Taymans 38b96e6c8c buffer: improve the buffer memory methods 
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.

Wim Taymans 7b0e4f27fb memory: make _new_wrapped take user_data and notify 
Make it possible to configure a GDestroyNotify and user_data for
gst_memory_new_wrapped() this allows for more flexible wrapping of foreign
memory blocks.

Wim Taymans a521252845 Add new GstMapInfo 
Use a structure to hold info about the mapping. The application then keeps track
of this state and we can use it to unmap the memory again later.

Wim Taymans 54fd50bfe1 buffer: add index to _take_memory() 
Add an index to gst_buffer_take_memory() so that we can also insert memory at a
certain offset. This is mostly interesting to prepend a header memory block to
the buffer.

Jan Schmidt 5dbe63c07a check: Hopefully fix an 'may be used uninitialized' warning on OS/X 2009-10-08 17:19:38 +01:00
Edward Hervey 3879cc60b1 tests: init more variables to avoid compiler warning on osx 
Init variable to avoid compiler warning and make the build bot happy
(the compiler most likely complains about this because it doesn't know
here that fail_unless will abort/exit in the path where it fails).

GstAdapter, and a unit test (based on the adapter one).
Fixes #585592.
