85c9543841 memory: group allocation parameters in a struct
Group the extra allocation parameters in a GstAllocationParams structure to make
it easier to deal with them and so that we can extend them later if needed.
Make gst_buffer_new_allocate() take the GstAllocationParams for added
functionality.
Add boxed type for GstAllocationParams.

edd2ffe4d4 memory: Add 0 padding
Change gst_allocator_alloc() so that we can also spicify flags and padding.
Add 2 new flags to mark the memory 0 prefixed/padded. This allows us to
remove some resizes in the base classes.
When allocating memory, memset prefix and padding with 0 when the flags tell
us to.
On resize, clear the zero padding flags if we can't guarantee the memory is
still 0 filled.
Update tests.

3d76e6011c query: also include padding in ALLOCATION query
Negotiating padding is needed on second thought so include it in the
ALLOCATION query.
Make the bufferpool take padding into account when allocating.
Make basesrc take padding into account.
Use padding and prefix when allocating in basetransform.

78ccf77fa3 bufferpool: use GstValueArray instead of GValueArray for storing options in the config
Since GValueArray is deprecated. It's all only internal anywhere here,
but if we use GstValueArray the option strings get serialized nicely
in the debug logs at least.

8b202df55d bufferpool: handle metadata in the pool
Mark all metadata on the allocated buffers with a POOLED flag. When a buffer
returns to the pool, remove all metadata that did not have the POOLED flag. This
makes sure that we never leave unknown metadata to the buffers in the pool.

733e94ada8 bufferpool: add options API to bufferpool
Make it possible to query the supported options of a bufferpool and enable
options. This is a bit more generic than the API to enable metadata. The purpose
is to make it possible to add new custom config options to the configuration of
the bufferpool when supported.

Rename the GstMemoryImpl to GstMemoryAllocator because that's really what it is.

Always use an allocator to allocate memory, use the default allocator when NULL
is passed.

allocator new method.

Keep track if the buffer is configured and block activation when not configured
yet.
Keep track of outstanding buffers and disallow configuration when not all
buffers are returned to the pool. We need to do this or else we might end up
with wrong buffers in the pool.
Add return value to set_active.
Small cleanups. Fix finalize.

provide. Does anyone have enough perl knowledge to add these features? I
allready changed the C code to output the pad definitions but my perl
knowledge is too limited, for now, to implement the rest of the needed
functionality...
