237f707c75 buffer: convert gst_buffer_* macros to functions 
GObject Introspection does not support macros.
This is needed for bindings. We can still add back
macros or inline functions again later if we think
it's worth it.

3b16efa1d1 miniobject: add lock functionality to GstMiniObject 
Move the locking methods from GstMemory to GstMiniObject.
Add a miniobject flag to enable LOCKABLE objects. LOCKABLE objects can
use the lock/unlock API to control the access to the object.
Add a minobject flag that allows you to lock an object in readonly mode.
Modify the _is_writable() method to check the shared counter for LOCKABLE
objects. This allows us to control writability separately from the refcount for
LOCKABLE objects.

76b30712f5 buffer: lock memory EXCLUSIVE

db65bfa129 buffer: fix the _get_mapped function 
Fix the internal _get_mapped function. gst_memory_make_mapped() takes ownership
of the memory so we need to keep an additional ref until we are done.

4c6228224f buffer: add _append_region function 
Make a gst_buffer_append_region() function that allows you to append a memory
region from one buffer to another. This is a more general version of
gst_buffer_append().

1be934f0dd miniobjects: pass copy, dispose and free function to gst_mini_object_init() 
So mini objects don't have to poke into the GstMiniObject part
of the structure. Saves lines of code, and seems slightly cleaner.
We don't have proper OO hierarchies or methods here after all.

12aefaa078 miniobject: remove the size field 
The size field is used by subclasses to store the total allocated size of the
memory for this miniobject. Because miniobject doesn't really do anything with
this field we can move it to the subclasses.

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.
