f3b0d3cdbe init: add _get_type() functions
Remove gst_mini_object_register() and add a GST_DEFINE_MINI_OBJECT macro to
define a _get_type() function for the boxed miniobject.
Remove a bunch of custom _get_type() functions and replace them with the
miniobject macro.
Rename some _init method to _priv_*_initialize() like the rest of them.

Inspired by patch from Johan Dahlin and see bug #657603

cc1686352d buffer: improve flags
Rename DROP to DECODE_ONLY.
Add DROPPABLE flag to mark buffers that can be dropped to save bandwidth without
destroying the stream.

4b3ffbc14d buffer: rename _CLIP to _DROP flag
We can also use a flag to indicate that a frame should be decoded but not
displayed regardless of the the segment boundaries so we use the more generic
_DROP.

fa8f9b50ea buffer: rework flags a little
Reorder buffer flags and add some new ones.
Remove the media specific flags, we can now easily do this with the FLAG_LAST
flag because we don't extend from GstBuffer anymore.

aefa1c67f8 buffer: return processed number of bytes
Make _fill, _extract and _memset return the actual number of bytes that were
handled in case the buffer size is less than the specified size.

8698a8c94e buffer: rename PREROLL -> LIVE flag
Rename the GST_BUFFER_FLAG_PREROLL to GST_BUFFER_FLAG_LIVE and give the new flag
a meaning. The old PREROLL flag never had a clear meaning.

abf6293639 buffer: add api to get the current memory offset
Also return the offset in a GstMemory block with the get_sizes() method. This
allows us to figure out how much prefix there is unused.
Change the resize function so that a negative offset can be given. This would
make it possible to resize the buffer so that the prefix becomes available.
Add gst_buffer_get_sizes() to return the offset and maxsize as well as the size.
Also change the buffer resize method so that we can specify a negative offset
to remove prefix bytes.

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.

b27ee30a35 buffer: make new _buffer_allocate method
Make a new method to allocate a buffer + memory that takes the allocator and the
alignment as parameters. Provide a macro for the old method but prefer to use
the new method to encourage plugins to negotiate the allocator properly.

c4751ec8c1 Revert "context: use context on buffers instead of caps"
This reverts commit 9ef1346b1f.

Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.

58060d7528 meta: separate add and get methods
Make separate api for getting and adding metadata. This allows us to pass extra
parameters to the init functions when creating metadata, which is needed for

8468dadc77 buffermeta: add beginnings of buffer metadata

something more performant.

39d486e526 buffer: add owner private as intermediate solution
Add an owner private field where the owner of a buffer can store some extra
information. We can use this to implement most of the subclassing that happens
now. Later this will be removed and replaced by arbitrary buffer metadata.
