Wim Taymans acb3ee9b2c memory: use allocators to allocate memory 
Rename the GstMemoryImpl to GstMemoryAllocator because that's really what it is.
Add an alloc vmethod to the allocator members.
Improve registration of allocators.
Add methods to get and set the default allocator
Always use an allocator to allocate memory, use the default allocator when NULL
is passed.
Add user_data to the allocator Info so that we can pass extra info to the
allocator new method.

Wim Taymans b5456cc6f4 caps: remove caps from buffers and pads

formats between element.

Wim Taymans 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.

Wim Taymans 9ef1346b1f context: use context on buffers instead of caps 
Put the srcpad context on buffers instead of caps. This allows us to associate
all the relevant info contained in events with a buffer.

Wim Taymans fa0d993372 meta: implement transform function 
Replace subbuffer and copy vmethods by a more generic transform function that
can then be parametrised by transform specific data. This should allow us to
implement make-writable and more future transform functions.

Wim Taymans 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
specific API implementations.

Wim Taymans 8468dadc77 buffermeta: add beginnings of buffer metadata 
Add first implementation of arbitrary buffer metadata. We use a simple linked
linked of slice allocated metadata chunks. Future implementations could use
something more performant.
Add get, remove, iterate methods to handle the metadata.
