ee235a6b07 miniobject: avoid race in bufferpool release
Avoid playing with the refcount to decide when a buffer has been recycled by the
dispose function. The problem is that we then temporarily can have a buffer with
a refcount > 1 being acquired from the pool, which is not writable. Instead use
a simple boolean return value from the dispose function to inform the called
that the object was recycled or not.

1a3f48f427 buffer: fix resize function some more
Don't remove memory blocks from the buffer when we clip and resize, instead set
the memory offset and size to 0. This allows us to make the buffer larger again
later.

a19baf77e7 buffer: improve size handling
Also handle the case where multiple empty memory blocks are in the buffer.
Add unit test for this.

a5ee20db3f buffer: fix _resize some more
Add more debug.
Alow resize to 0 bytes.
Do clipping correctly.
Add more unit tests. Also add a failing test: when we resize to 0 and then
try to resize back to the original size it fails because the memory was
removed.

8461249f22 buffer: fix negative offsets some more
Allow for negative offsets when doing memory copy and share.
Add fast path in the _get_sizes() function.
Fix resize for negative offset and expanding the buffer.
Add some unit tests.

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.

a1f6e02149 buffer: fix guards for gst_buffer_take_memory()
Since idx = -1 makes it default to idx=len, len is also
a valid input idx.

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.

eeb07b3f3d buffer: add support for buffer in memory
Fix the code to support allocating the buffer and memory in one memory block.
Add an extra variable to store the memory of the buffer.
This code is disabled still because of complications.

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.

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.

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.
